Domain I - Ophthalmic Optics

1.	A lens' focal length can be altered by:
		a. Changing the curvature of one surface
		b. Coating the surface
		c. Making the lens bigger
		d. Making the lens smaller
Changing the curvature of one surface. A lens with a higher angle of curvature will have a shorter focal length because the light waves are refracted at a greater angle with respect to the optical axis of the lens. As the refractive index increases or becomes more curved, the focal length of the lens decreases. Coating the surface of the lens will only change the properties of the surface not the focal length and changing the diameter while keeping the curvature of the surfaces of the lens the same, does not impact the angle of curvature or how light waves are refracted. Incorrect answer. Please choose another answer.

2.	The refraction that a patient likes the most is known as what?
		a. Cycloplegic refraction
		b. Comfortable refraction
		c. Objective refraction
		d. Subjective refraction
The refraction that a patient likes most is the subjective refraction. The subjective refraction is a refinement of the objective refraction which requires patient input while looking through a phoropter with various spherical and cylindrical trial lenses to achieve what the prescription the patient prefers. A cycloplegic refraction is used to identify a patient's total refractive error by temporarily paralyzing the muscles that help in focusing the eye using eye drops. An objective refraction is obtained by the use of retinoscopy or an auto refractor and does not require any patient input. Incorrect answer. Please choose another answer.

3.	What is a Fresnel prism?
		a. The name for the press-on prisms that can be added to an existing lens
		b. The name for a prism ground into a lens
		c. The name of the person who discovered the need for prism in lenses
		d. None of the above
A Fresnel prism is the name for press-on prisms that come on a plastic sheet in various strengths that can be cut and adhered to a patient's existing lens or lenses to prevent double vision. A Fresnel prism is used as a temporary treatment if a patient's double vision is expected to change over time, or as a trial before a more permanent ground in prism is built into new lenses. Incorrect answer. Please choose another answer.

4.	Which is the best option for a patient who wants to be able to see up close at the top of their glasses and at the bottom of their glasses?
		a. Order a trifocal lens
		b. Order a single vision lens
		c. Request the lab to make an upside-down bifocal lens
		d. Order a double d lens
A double d lens has a bifocal segment at the top of a lens in addition to a bifocal segment at the bottom of the lens. This allows the wearer to be able to see up close at the top and the bottom of their glasses while allowing them to see distance through the middle. A trifocal lens will allow a wearer to see distance at the top of the lens, intermediate distance through the upper most portion of the segment, and close up at the bottom portion of the segment. A single vision will allow the wearer to see at only one distance through the entire lens, therefore they will not be able to see distance and close up through the same lens. While it is possible to request that the lab make an upside-down bifocal lens, the wearer would only be able to see close up through the top of the lens and distance through the rest of the lens. Incorrect answer. Please choose another answer.

5.	What is the vision range in the intermediate zone of a trifocal?
		a. 12 to 36 inches
		b. 10 to 18 inches
		c. 18 to 24 inches
		d. None of the above
18 to 24 inches is defined as the intermediate or mid-range. Anything beyond 24 inches is considered distance range, and anything from 0 to 18 inches is considered close range. Incorrect answer. Please choose another answer.

6.	Which lens material is recommended for drill mounted frames?
		a. Glass
		b. Trivex
		c. Plastic
		d. Polycarbonate
The best choice of lens material today for a drill mounted frame is Trivex. Before Trivex, polycarbonate was the lens material of choice, but Trivex has a far superior tensile strength over polycarbonate. The holes that are drilled into a polycarbonate lens tend to "stretch" over time resulting in lenses becoming loose in the frame. Drilling holes in plastic and glass lens materials will cause them to shatter. Incorrect answer. Please choose another answer.

7.	All of the following steps are performed to determine a patient's refraction, except:
		a. Visual field test
		b. Tonometry
		c. Measurement of visual acuity
		d. External examination
While tonometry is performed during an eye examination, it is performed to determine the interocular pressure of the eyes, not to determine the patient's refractive error. A visual field test is performed to determine how well a patient can see objects on the periphery of vision without moving the eyes. Visual acuity is a measurement of the sharpness of one's vision using a projected eye chart to measure the distance visual acuity and a handheld eye chart to measure the near visual acuity. An external examination is performed to the alignment and position of the eyes, and to evaluate the conjunctive, sclera, cornea, iris, pupils, and extraocular movements. Incorrect answer. Please choose another answer.

8.	What does the term "ametropia" mean?
		a. Errors were made by the optician in interpreting the prescription
		b. A refraction was done incorrectly
		c. The eye has an abnormality preventing light from focusing on the retina correctly
		d. A and B only
Ametropia refers to some type of abnormality of the eye preventing light from being able to properly focus on the retina. It is not due to the optician's error in interpreting the prescription. A refraction that was done incorrectly by the practitioner is not a refractive error. Incorrect answer. Please choose another answer.

9.	Meniscus, equiconcave and flat concave are types of:
		a. Astigmatic lenses
		b. Minus lenses
		c. Plus lenses
		d. Spherocylinder lenses
Minus lenses correct for near-sightedness or myopia which means a person can see objects close but cannot see far away. Lenses used to correct this are flatter on the front surface and more curved on the backside making the thinnest point in the center of the lens. A lens which has two spherical curved surfaces, concave on one side and convex on the other side is called a meniscus lens. When both surfaces of the lens are concave, therefore having the same focal length, it is called an equiconcave lens. Flat concave lenses have a flat surface on one side and a spherical surface on the other. Equiconvex, flat convex and meniscus are types of plus lenses. A meniscus lens can be either a plus or minus lens however, concave refers to minus lenses while, convex refers to plus lenses. Incorrect answer. Please choose another answer.

10.	What kind of lens has one convex and one concave surface?
		a. Biconcave
		b. Biconvex
		c. Meniscus
		d. Plano-convex
A meniscus lens has one convex and one concave surface. A negative meniscus is thinner at the center than at the edges and a positive meniscus lens is steeper on the convex side making it thicker at the center and thinner on the edges. Meniscus lenses are used for vision correction in both myopic and hyperopic eyes. Biconcave lenses have two concave surfaces and biconvex have two convex surfaces. A plano-convex lens has one flat surface and one convex surface. Incorrect answer. Please choose another answer.

11.	Axis is the notation of power on a lens.
		True
		False
False - The axis of a lens notates the position of the astigmatism power, not the amount of power. The sphere denotes the power of the lens required and the cylinder is the amount of power needed to correct for astigmatism. Incorrect answer. Please choose another answer.

12.	Which word is used to describe light's changing direction as it passes from one medium to another?
		a. Diffusion
		b. Reflection
		c. Refraction
		d. Retraction
Refraction refers to how light slows and bends when passing from air, a light-density medium into transparent glass or plastic, a high-density medium. When light passes from air through a denser medium such as a lens, the light will bend toward the normal because of the changing velocity at the surface between the two media. Diffusion refers to light being scattered when passing through an irregular surface. Reflection is when light is bounced off a smooth surface, the light will reflect at the same angle as it does when it hits the surface. Dispersion is when white light is split into its component colors: red, orange, yellow, green, blue, and violet, when refracted. Incorrect answer. Please choose another answer.

Domain II - Ocular Anatomy, Physiology, Pathology and Refraction

13.	What controls the amount of light that enters the eye?
		a. Crystalline Lens
		b. Fovea
		c. Iris
		d. Pupil
The amount of light entering the eye is controlled by the muscles of the iris. These muscles control the size of the pupil, making it larger (dilated) to allow more light in or smaller (constricted) to restrict the amount of light entering. Under low light conditions, the iris opens making the pupil larger and they constrict in bright light conditions. The crystalline lens is located posterior to the iris and is made up of mostly proteins producing one third of the eye's natural power and focuses light into an image on the retina. In the center of the posterior portion of the retina is a small, flat spot called the fovea, which is responsible for high-acuity vision. Incorrect answer. Please choose another answer.

14.	What is the term used to describe the eye's tendency to turn from its normal position?
		a. Exophoria
		b. Exotropia
		c. Phoria
		d. Tropia
A phoria is defined as a misalignment of the eyes, appearing only when binocular viewing is broken. It is only apparent some of the time and occurs when the eyes are fatigued, and the person cannot compensate for the deviation. Unlike a phoria, a tropia is when the eye never straightens out and is constantly turned in, out, up, or down. Exophoria occurs when the eyes drift outward but is temporary, usually caused when the eyes are tired or stressed, or during close vision tasks. Exotropia is also an outward turning of the eyes; however, it is more frequent and noticeable, even when both eyes are open and trying to work together. Exophoria occurs when the eyes drift outward but is temporary, usually caused when the eyes are tired or stressed, or during close vision tasks. Exotropia is also an outward turning of the eyes, however, it is more frequent and noticeable, even when both eyes are open and trying to work together. Incorrect answer. Please choose another answer.

15.	What is the refractive condition in which light focuses directly on the retina?
		a. Emmetropia
		b. Hyperopia
		c. Myopia
		d. Presbyopia
Emmetropia is the medical term for naturally occurring vision. An emmetropic eye does not require vision correction because the light entering the eye focuses directly on the retina. Hyperopia (or farsightedness) occurs when the light focuses behind the retina and Myopia (or nearsightedness) is when the light focuses in front of the retina. Incorrect answer. Please choose another answer.

16.	How is multifocal height usually measured?
		a. From the lower edge of the lens
		b. From the upper edge of the lens
		c. From the lower edge of the frame
		d. From the upper edge of the frame
A multifocal height is measured from the lower edge of the lens to the center of the pupil. It is always important to adjust the frame to the person before measuring to allow for accurate placement of the multifocal. Taking this measurement from the lower edge of the frame will add extra millimeters to the measurement and cause the multifocal to be placed too high. Measuring to the lower edge of the frame or lens will most likely cause the multifocal to be set too low. Incorrect answer. Please choose another answer.

17.	Which of the following is an advantage to a titanium frame?
		a. Corrosion resistant
		b. Easy to adjust
		c. Returns to original shape after bending
		d. None of the above
When titanium is exposed to air and moisture, it immediately forms a strong protective oxide film making it 100% corrosion resistant. Another advantage of a titanium frame is that the metal is hypoallergenic and will not cause an allergic reaction for those with sensitive skin or have a nickel allergy. The rigidity of the metal allows the frame to hold its shape making it more difficult, not easier to adjust for the dispenser. Memory metal frames, or nickel titanium alloys are not a pure titanium frame; they will return to its original shape after bending and are made up of 50% nickel and 50% titanium. Incorrect answer. Please choose another answer.

18.	Which term is used to describe the outward inclination of the bottom of a framed lens?
		a. Pantoscopic
		b. Periscopic
		c. Retractive
		d. Retroscopic
Retroscopic tilt is used to describe the adjustment made to a frame which brings the bottom edge of the frame front outward from the face. This adjustment is made to prevent a frame from resting on a person's cheek. Pantoscopic tilt will maximize the amount of the bridge surface that rests on the nose and will also raise the ocular center of the lens 1mm for every 2 degrees of tilt. Conversely, retroscopic tilt will lower the ocular center. All frames should have some pantoscopic tilt to optimize vision by balancing the vertex in the 90-degree meridian. Periscopic, as in periscopic vision, refers to having distinct vision all around and not only in a distinct or direct line. Retractive is an adjective that describes something that withdraws. Incorrect answer. Please choose another answer.

19.	Aphakia is:
		a. The absence of accommodation
		b. The absence of the crystalline lens
		c. The presence of a cataract
		d. The presence of a refractive error
The absence of the crystalline lens is called aphakia. This condition can either be from birth or caused by injury. The crystalline lens is most often removed by an Ophthalmologist during cataract surgery and an artificial lens is put in its place to correct vision. Accommodation refers to the eyes' diminished ability to focus between distances. The presence of a cataract or a refractive error may result in the removal of the crystalline lens during cataract surgery, however, it is not the definition of aphakia. Incorrect answer. Please choose another answer.

20.	A patient with astigmatism has a ________ cornea.
		a. Clear
		b. Cloudy
		c. Misshapen
		d. Round
The cornea is the clear outer layer of the eye with the thickest part in the middle layer made up of water and a protein called collagen. The collagen helps keep the cornea's regular round shape and makes it flexible and strong. When either the front surface of the eye, the cornea, or the lens inside the eye have mismatched or misshapen curves, astigmatism occurs causing blurred vision at all distances. When the cornea is cloudy, it is usually a sign of scarring, infection, an abrasion or swelling of the eye. Incorrect answer. Please choose another answer.

21.	The cornea's index of refraction is:
		a. 1.31
		b. 1.37
		c. 1.47
		d. 1.51
Most of the refraction is at the cornea-air surface of the eye. The rays pass from the cornea into the aqueous humor (the watery fluid filling the space in front of the eyeball between the lens and the cornea), which has a refractive index of approximately 1.336, making the refractive index of the cornea about 1.37. Incorrect answer. Please choose another answer.

Domain III - Ophthalmic Products

22.	Frame materials are available in which two forms?
		a. Hard and soft
		b. Metal and plastic
		c. Rigid and flexible
		d. Round and square
Metal frames include materials such as Monel which is a mixture of a broad range of metals and is the most used material to manufacture eyeglass frames. Other metals include titanium and beta-titanium which offer light weight and durable options. Beryllium is a steel-gray metal that is light weight, very strong and flexible and is available in a variety of colors. Zyl is a plastic material that is very cost-effective and extremely light weight. Nylon is a material that is used primarily for sport or performance frames due to its resistance to hot and cold, and are more flexible, yet rigid enough to hold its shape. Incorrect answer. Please choose another answer.

23.	A new lens paced in the eye after cataract surgery is known as:
		a. Pseudophakia
		b. Aphakia
		c. Myopia
		d. Presbyopia
Pseudophakia is a Latin word for false lens. It is a type of intraocular lens placed on the eye during cataract surgery after removal of the cloudy lens. Aphakia refers to a patient that does not have a lens in the eye. Some people are born without a lens in one or both eyes. It can also be a result of a traumatic injury to the eye, in addition to having a cloudy lens removed due to cataracts but not replaced with a new lens. Myopia is a vision condition in which objects that are farther away appear clear, but objects that are near appear clear. Presbyopia is when your eyes gradually lose the ability to focus on things close up due to the lens in the eye becoming more rigid and losing it's flexibility. Incorrect answer. Please choose another answer.

24.	Which frame materials are hypoallergenic?
		a. Aluminum
		b. Titanium
		c. Both A and B
		d. Monel
Both aluminum and titanium are hypoallergenic frame materials and are the best choices for people with metal allergies as the frames are only made with aluminum or titanium. Although Monel frames are the most commonly made, these frames are not hypoallergenic as they are made with a combination of various metals. Incorrect answer. Please choose another answer.

25.	Which is the best frame choice for the following prescription? OD -6.00 sph OS -2.00 sph
		a. Grooved, rimless frame
		b. Large, round plastic frame
		c. Small, round plastic frame
		d. Drill mount frame
A small, round plastic frame would be the best choice because the small size and the optical centers of the lens would not have to be decentered as much causing unwanted thickness. A drill mount frame would be the worst frame choice for this prescription because of the significant difference in the power of the two lenses. One lens would be noticeably thicker than the other side and it could also reduce the integrity of the frame. While not the worst choice, a grooved, rimless frame is not an ideal frame for this prescription due to the edge thickness of the lenses, which would not be cosmetically appealing. A large plastic frame would not be ideal with this prescription because the larger the frame is, the thicker the lens will be. Incorrect answer. Please choose another answer.

26.	The reference marks on a progressive lens allow you to:
		a. Determine the add power of the lens
		b. Know who the manufacturer of the lens is
		c. Determine the distance reference points on the lens
		d. All of the above
The reference marks on a progressive lens will give you the add power of the lens by a number that is indicated just below the reference mark. The shape and style of the reference mark identify the manufacturer of the lens. This is done by cross referencing the symbol in a progressive identifier book. The reference marks also determine the distance reference points on the lens with the help of a layout chart provided by the manufacturer, and also help to determine if there is unwanted prism in the lens. Incorrect answer. Please choose another answer.

27.	What does the term "short corridor" mean in reference to a progressive lens?
		a. A shorter amount of space in the frame vertically for all of the ranges of vision going from far to near
		b. A shorter amount of space in the lens for the distance prescription
		c. A shorter amount of space in the lens for the near prescription
		d. A shorter amount of width of the progressive lens
A short corridor progressive lens refers to a shorter amount of vertical space for all the ranges of vision from far to near. Trying to fit a regular progressive lens in a small frame with a short "B" measurement will result in cutting off part of the distance at the top or some of the near at the bottom resulting in the patient's inability to see at all distances. Short corridor lenses are recommended for small frames with short "B" measurements. Incorrect answer. Please choose another answer.

28.	Polarized lenses are not recommended for:
		a. Snow skiers
		b. Pilots
		c. Fisherman
		d. Surfers
The Federal Aviation Administration recommends pilots refrain from wearing polarized lenses while flying. Pilots must look at LCD screens that are made with polarization when flying. That means that if they wear polarized lenses while flying, when they look at the polarized LCD screen, the polarization of the screen and the glasses will block each other out and will be black. Snow skiers, fisherman, and surfers will all benefit tremendously by polarized lenses due to the amount of time they spend outdoors as the polarized lenses will block the glare that comes from looking at snow or water. Incorrect answer. Please choose another answer.

29.	Which frame type would be the best choice for a child who suffers from a seizure disorder?
		a. A nylon frame
		b. A memory metal frame
		c. A metal frame with spring hinges
		d. A drill mount frame
A memory metal would be the best choice for a child who suffers from a seizure disorder as the frame can be bent numerous times yet keep its original shape. While nylon frames are a good choice for children who play sports as they are highly impact-resistant, nylon frames will still break if bent in half. A metal frame with spring hinges is durable, but the metal property of the frame will not keep the frame from getting repetitively bent which will decrease the overall strength of the frame over time. A drill mount frame would be the worst choice of the ones listed as they are fragile and some have protruding screws in the lens which could cause an injury to the eye. Incorrect answer. Please choose another answer.

30.	Which frame adjustment lowers the front of the frame?
		a. Bending the pad arms down
		b. Bringing the pads closer together
		c. More pantoscopic tilt
		d. Spreading pads further apart
Spreading the pads further apart will increase the space between them and in turn will lower the frame front. Bending the pad arms down and bringing the pads closer together will raise the frame front. Adding pantoscopic tilt which brings the bottom of the frame edge towards the cheeks, will raise the frame front and the ocular center of the lenses. Incorrect answer. Please choose another answer.

31.	Which lens characteristic corrects astigmatism?
		a. Cylinder power
		b. Minus power
		c. Plus power
		d. Prism power
Cylinder power indicates the amount of lens power needed to correct for astigmatism and must include an axis between 1 and 180 indicating the orientation of the astigmatism. Minus and plus powers are the powers needed to correct for near or farsightedness and are called the sphere power. Prism correction is used in eyeglasses to correct for double vision allowing the person to align two images so only one image is seen. Prism must include a direction, either in or out, or up or down depending on orientation of the doubled image. Incorrect answer. Please choose another answer.

Domain IV - Instrumentation

32.	Which instrument measures vertex distance?
		a. Distometer
		b. Lensometer
		c. Polariscope
		d. Vertometer
Distometer. Vertex distance is the distance between the front surface of the cornea and the backside of a corrective lens mounted in a frame to be worn by the patient. Measuring the vertex distance with a distometer for prescriptions greater than 4 diopters ensures the accuracy of the necessary power. When plus lenses are moved toward the eye, perceived power is lost; when moved away from the eye, perceived power is gained. For minus lenses, it is the opposite: when lenses move toward the eye, perceived power is gained and when they move away from the eye, perceived power is lost. A lensometer is an instrument used in dispensaries to determine the diopter powers of a lens. A vertometer also measures the diopter power of a lens but is more precise and is used in laboratories to locate and mark the optical center of a lens for edging and mounting. A polariscope is used during the lens inspection process to detect stresses or defects in different types of lens materials. Incorrect answer. Please choose another answer.

33.	What material has the most favorable optical properties?
		a. Crown glass
		b. Plastic
		c. Polycarbonate
		d. Trivex
Crown Glass has a low index of refraction of 1.52 and an Abbe value of 59, which means that light travels faster through the material, making crown glass the leading choice for the sharpest optics. Higher Abbe numbers mean less dispersion, higher visual quality and reduced chromatic aberration. Crown Glass is also the most scratch-resistant material. Lenses with a higher refractive index are denser making them thinner and more attractive but they have more aberrations, decreasing the visual quality of the lens. Incorrect answer. Please choose another answer.

34.	A polariscope is used to detect internal lens stress.
		True
		False
True - A polariscope used in optical laboratories detects internal lens stress to ensure the quality of the product. It is made up of a light source and two crossed polarized lenses to detect any imperfections in a lens caused by manufacturing. Incorrect answer. Please choose another answer.

35.	A monocular PD is given as one number.
		True
		False
False - Mono meaning one, makes this confusing, however a monocular pupillary distance means each eye is assessed separately, resulting in two numbers, one for each eye. When a binocular pupillary distance is taken, the PD for each eye is added together, resulting in one number. Incorrect answer. Please choose another answer.

36.	To what does a ptosis crutch give support?
		a. Lower lid
		b. Nasal bridge
		c. Nose pads
		d. Upper lid
Upper Lid. Ptosis occurs when the upper eyelid is not functioning properly or has grown weak and struggles to open and close on its own. A Ptosis crutch is installed onto the pair of glasses aiding the lid to function properly without surgery. The drooping lid is supported by the crutch which is a bar attached to the inside of the eyewire frame. A fold above the eye is created by the crutch raising it above the pupil. Incorrect answer. Please choose another answer.

Domain V - Dispensing Procedures

37.	What is the best lens treatment to reduce water and road surface glare?
		a. AR
		b. Dark tint
		c. Photochromic
		d. Polarized
Polarized lenses reduce the glare of surfaces, such as pavement, snow or water with a chemical filter that absorbs the incoming horizontal light and allows only vertical light to pass through the lens. This is often confused with Anti-Reflective lenses which reduce reflections on the surfaces of the coated lens and does not reduce glare on external surfaces. Dark tint and Photochromic lenses will allow less light to pass through the lens making it easier to see in bright sunlight however, neither will reduce the glare on surfaces. Incorrect answer. Please choose another answer.

38.	What color of sunglasses are most preferred by pilots?
		a. Orange
		b. Gray green
		c. Brown
		d. Gray
Most pilots prefer a gray green lens in their sunglasses because it does not distort other colors, and on hazy or cloudy days, the gray green combination color enhances contrast. While orange lenses may distort other colors, they are great for indoor sports like basketball or volleyball where there are lower lighting conditions. Orange lenses also provide increased depth perception. Brown and gray lenses are what you will find in most standard sunglasses for everyday use such as driving or sight-seeing because they reduce a lot of glare. Incorrect answer. Please choose another answer.

39.	What should you do after adjusting the angle on a patient's glasses to correct the imbalance on the patient's face?
		a. Check the temple fold alignment
		b. Adjust the nosepieces
		c. Shorten the temples
		d. None of the above
After adjusting the angle of a patient's glasses to correct any alignment issues, you should always check the temple fold alignment. When temples are closed, they should overlap and be parallel to the top of the frame. An improper fold alignment can result in the eyeglasses not properly fitting inside the patient's case. Adjusting the nose pieces or shortening the temples will not correct the imbalance. Incorrect answer. Please choose another answer.

40.	An elderly patient comes in with her middle-aged daughter to purchase new eyewear. Which of the following is correct procedure?
		a. Speak to the daughter first about what the elderly patient wants
		b. Ask if they purchased with you before
		c. Both A and B
		d. Neither A nor B
If an elderly patient comes in to purchase eyeglasses with her middle-aged daughter, you should not make assumptions about the patient's ability to speak for herself and to make her own decisions. All patients should be treated the same. Assumptions should not be made about social or economic status. Incorrect answer. Please choose another answer.

41.	If a patient comes in to complain about eyeglasses just purchased from you, what should you do?
		a. Ask him for his receipt
		b. Ask him to explain the problem he's having with his eyeglasses to you
		c. Tell him there is a no return or exchange policy
		d. Carefully explain to him that his glasses were made correctly
If a patient comes in to complain about his glasses, you should ask him to explain he problems he is having. You should listen to the patient and suggest an option to rectify the problem or issues he's having in a calm manner. It's important to make him feel like you care and that you are genuinely interested in helping him. Asking him for his receipt, explaining the return or exchange policy, or telling him his glasses were made correctly before listening to him is only going to cause the patient to become upset and assume that you don't care about helping him. Incorrect answer. Please choose another answer.

42.	Which of the following is on the list of things which should be explained to a patient when picking up their new eyewear?
		a. Encourage them to come in periodically for routine adjustments
		b. The use of any they have on hand to clean their eyeglasses
		c. The proper technique for keeping their eyewear clean and how to handle their eyewear.
		d. Both a and c
When a patient is picking up their new eyewear they should be encouraged to put on and take off their eyewear with both hands to avoid the risk of accidently bending them. Explaining the proper technique for keeping their new eyewear clean is important to prevent scratches. Encouraging the use of an eyeglass case when not wearing their new eyewear will help to avoid accidents happening to them, help to prevent loss, and help to further reduce scratches or bending them. Common household cleaners should not be used to clean eyewear. Incorrect answer. Please choose another answer.

43.	What can be done if a patient who has a high plus lens is complaining that their new eyeglasses make their eyes appear too big?
		a. Tell them that this is a natural consequence of their prescription
		b. Suggest that you change the lens material of their glasses
		c. Offer to tint their glasses
		d. Offer to select a new frame
Plus lenses will naturally magnify the wearer's eyes. To rectify this, select an aspheric lens material with a flatter front surface. This will reduce the magnification of the plus power and make the wearer's eyes look more natural. Tinting the glasses will not lessen the magnified appearance of the eyes. The type of frame will not affect the visual appearance of the magnified eyes. Incorrect answer. Please choose another answer.

44.	Why is it important at dispensing to place the wearer's new eyewear on them yourself?
		a. To establish control of the dispensing
		b. To ensure the patient does not drop the glasses
		c. To prevent voiding any warranties
		d. To speed up the dispensing process
Personally placing the wearer's new eyeglasses on them establishes control of the dispensing procedure. You are the professional and you need to demonstrate that you are taking care of the patient, and that you know what you are doing. This also allows you to be able to feel with your fingers for any adjustments that need to be made right away. You should never rush a patient through the dispensing process. Incorrect answer. Please choose another answer.

45.	What should you always do when a parent is purchasing their child's first pair of prescription eyewear?
		a. Explain to the parent the safety of the lenses
		b. Explain to the parent the care needed for the glasses
		c. Explain to the parent the qualities of the lenses
		d. All of the above.
When a parent is purchasing their child's first pair of prescription eyewear, you should explain to them how to clean them, the quality of the lenses they are receiving, and the safety of the lenses. Without getting technical, always give the parent as much information as possible to make them feel comfortable about the choices they have made for their child. Incorrect answer. Please choose another answer.

46.	The hard resin material used in plastic lenses is known as:
		a. Cellulose acetate
