3. What should the patient be told about an adaptation period with computer-specific glasses? A. Usually no adaptation period is required B. It should take only an hour or two for adaptation C. Patients should be comfortable with their new computer Rx within 1 to 2 weeks D. Avoid discussing adaptation time with the patient
4. How will the added plus power in a computer Rx affect the patient? A. Their distance vision will be somewhat limited B. If they don't require glasses for full time, they might consider using single vision lenses in their computer glasses C. There are other options they can choose D. All of the above
5. When is single vision a good choice for computer eyewear? A. When computer use is constant and they can tolerate some distance blur B. When they are a moderate presbyope C. When they are an advanced presbyope D. Single vision is never a good choice
6. What are the drawbacks to using bifocals for computer eyewear? A. Bifocals provide no area for viewing computer screen B. Segs are usually too low and have too much plus power C. Bifocals are a low tech answer to a high tech problem D. All of the above
7. What are the drawbacks in using progressives for computer eyewear? A. Intermediate and near areas are too narrow B. They usually require wearers to tilt their head back by 20° C. They are too expensive D. Both A and B
8. What is the best lens choice for presbyopic computer users? A. Single vision B. Flat Top Bifocal C. General Purpose PAL D. Variable Focus Near lens
9. What variations are available in Variable Focus Near lenses? A. They are produced with add powers ranging from +1.00D to +3.00D B. They are produced with add powers ranging from +1.00D to +2.50D C. They are produced in 2 or 3 power shifts D. One variation fits all
10. In fitting Variable Focus Near lenses, which of the following is most important? A. Taking monocular PDs B. Frame's "B" measurement should be 29mm or more C. Dot center of pupil with selected frame in place D. All of the above
11. In fitting Variable Focus Near lenses, the correction at the fitting cross will be: A. The near Rx less the full amount of the power shift B. The near Rx less 20% of the power shift C. The near Rx less 50 % of the power shift D. The near Rx less 80% of the power shift
12. What information does the lab require when ordering Variable Focus Near lenses? A. Patient's distance Rx and their computer working distance B. Patient's distance Rx, reading add, and computer add power determined by computer tester if available C. Patient's total near power and the power shift desired D. B or C
13. Is an anti-reflection coating useful for computer eyewear? A. There is no need for AR when working at computers B. Use AR only when requested by the patient C. Suggest AR only with stronger corrections D. AR coatings reduce office environment glare and are highly recommended
14. Should UV protection be recommended for computer glasses? A. Always B. Never C. UV protection is not necessary unless the patient desires it
15. Should tints be suggested for computer eyewear? A. Tints should never be suggested for computer glasses B. For brightly-lit offices with fluorescent lights, recommend a 15% absorption tint C. For brightly-lit offices with fluorescent lights, recommend an 8% absorption tint D. Tints should always be used for computer eyewear
