Question 1

Preventive measures in hazardous workplaces that help reduce the incidence of ocular injuries include

Accepted Answer

Preventive measures in hazardous workplaces that can help reduce the incidence of ocular injuries include detection of ocular disabilities before placement of workers in specific jobs; the wearing of protective googles, visors, and masks; and the education of workers in eye safety. Once an injury has occurred, early treatment of eye injuries can reduce the chance of irreversible damage.

Question 2

What type of lenses reduce glare?

Accepted Answer

Polarized lenses reduce glare for the wearer. These lenses are useful for those who spend a lot of time outdoors or even for anyone who drives. They can also help reduce light sensitivity in certain patients such as those who have had cataract surgery.

Question 3

What type of lenses darken when outdoors and lighten when indoors?

Accepted Answer

Photochromic lenses darken when outdoors and lighten when indoors. These lenses are sensitive to UV rays and, when exposed, are able to darken in order to protect the patient's eyes.

Question 4

Asking whether or not a patient wears contact lenses or eyeglasses is part of the:

Accepted Answer

Asking a patient whether or not they wear contact lenses or eyeglasses is considered part of the patient's ocular history. The ophthalmic assistant is typically responsible for collecting this information from the patient during the history-taking process. If available, the prescription strength of any corrective lenses the patient wears should also be recorded.

Question 5

Which of the following is not part of history taking?

Accepted Answer

A contrast sensitivity assessment is not part of history taking. Contrast sensitivity assessments are principally administered when a patient reports night blindness or suffers from cataracts.

Question 6

When taking a family history, all of the following should be included except:

Accepted Answer

A patient's mother-in-law should not be included in a patient's family history because there is no genetic link between a patient and their in-laws. Moreover, it is also not necessary to ask about a spouse's medical history. Grandmothers, sisters, and sons all share genetic links with the patient and should therefore be included in a family history.

Question 7

A patient's interim history refers to which of the following?

Accepted Answer

A patient's interim history refers to the history of the patient's condition since their previous visit. During a follow-up consultation, it is important to ask whether a patient's condition has improved or worsened since the previous visit. This is done to determine if the treatment given to the patient has been effective or not. It is also important to ask a patient whether or not they have been properly using prescribed medications.

Question 8

After how much waiting time does patient dissatisfaction begin to climb dramatically?

Accepted Answer

After 30 minutes of waiting time, patient dissatisfaction begins to climb dramatically. In any case where delay is unavoidable, the patient should be given an explanation for the long wait time and how much longer they can expect to be waiting.

Question 9

If a patient has a question about a diagnosis or a treatment it is best to:

Accepted Answer

If a patient has a question about a diagnosis or a treatment it is best to refer the patient to the ophthalmologist. You do not want to misinform a patient or go beyond the scope of practice that an ophthalmic assistant is legally bound to.

Question 10

What would be the best lens color and material for a patient who needs a prescription and loves to play baseball during the day?

Accepted Answer

The best lens for a baseball player who plays during the day and needs to wear prescription eyewear would be a polycarb lens that is polarized and has an added anti-reflective coat on the back side of the lens.
Polycarb or Trivex are the best materials for impact resistance. The polarized gray lens will cut glare, give more definition and allow the player to see well. The anti-reflective coating on the back side will eliminate all glare that will hit the back side of the lens.

Question 11

Which is the most popular color that most pilots prefer for sunglasses?

Accepted Answer

The gray green color has always been a popular choice for sunglasses for pilots.
When looking through a gray green color, it does not distort other colors, and in hazy conditions the grey green combination enhances contrast. It is not recommended by the FAA for pilots to wear polarized lenses as they may interfere with seeing through the windshield and the pilot may not be able to see the instrument panel.

Question 12

The optimum lens color for outdoor tennis players is __________ . Choose all that apply.

Accepted Answer

Both orange and brown lenses would be the optimum lens color for a tennis player.
Orange or brown lenses will pick up the color of the yellow ball better, provide more contrast and still give the darkness needed for a sunglass. Additionally these lenses should be polarized to completely eliminate glare from tennis court surfaces and annoying glare from surrounding surfaces.
Yellow will give the needed contrast but will not be dark enough to prevent squinting. A gray color will not give as much contrast as either orange or brown.

Question 13

The best lens color for a hunter or target shooter is yellow.

Accepted Answer

Hunters and target shooters benefit the most from a yellow lens.
The color yellow will provide improved image contrast to help with the target. In addition, it will absorb scattered blue light.

Question 14

Prescription patients who have dry eye syndrome and love to be outdoors would benefit from:

Accepted Answer

Prescription patients who have dry eye syndrome and love being outdoors would benefit from wrapped sunglasses.
There are manufacturers of sunglasses that will fit tight and wrap. Wrapped sunglasses will block out wind, dirt and debris.

Question 15

A car mechanic who has presbyopia and works underneath vehicles would benefit from which lens?

Accepted Answer

A car mechanic who has presbyopia and works underneath vehicles would benefit from a Double D lens.
The Double D lens would allow the mechanic to view the car up close through the top of the glasses as well as below. This only requires eye movement and not head movement, which is critical in small confined areas.

Question 16

Patients who have macular degeneration would benefit by adding which color to their lenses for full-time wear? Choose all that apply.

Accepted Answer

Patients who have macular degeneration would benefit by adding either red orange or orange color tint to their full-time wear glasses.
Red orange and orange tints will help by reducing the amount of shortwave light entering the eye, thereby enhancing contrast and reducing glare.

Question 17

Certain occupations require employees who have prescriptions to use safety glasses.

Accepted Answer

Certain occupations do require employees who have prescriptions to use safety glasses.
The specific requirements as to the ANSI standards for each occupation are clearly stated and must be adhered to.

Question 18

Children who play sports should have a second pair of glasses specifically made for their sports activity.

Accepted Answer

Children who play sports should have a second pair of glasses specifically made for their sports activity.
Children need to have their glasses be impact resistant. In order to protect children's eyes it is important to use safety frames and lenses. The frames should fit snuggly to the child's face and not have room for jarring. The lenses should be made from either polycarb or Trivex material.

Question 19

Panoscopic tilt on most patients' frames should be at:

Accepted Answer

Panoscopic tilt should be at 8 - 10 degrees for most patients.
Before a frame is dispensed it should be looked at and adjusted to bench adjustment. This is when the frame is placed on a flat surface upside down and both eye wires and tips of both temples rest on the surface. The frame should not be torqued prior to dispensing.

Question 20

If the left side of a patient's frame is too low, you should __________ . Choose all that apply.

Accepted Answer

If the left side of a patient's frame is too low, you should angle the left temple down or angle the right temple up to correct the fit.
