3. 3. Not all patients can adapt to prescribed glasses. According to some research, the average rate of spectacle non-tolerance (cases where patients return with complaints to optical practices) was found to be:

• 0.9%

• 2.3%

• 4.1%

• under-plused; under-minused; add too low

• Over-plused; under-minused; add too low

• Over-plused; under-minused; add too high

5. In a study investigating the effects of low-addition convex lenses on reading rate and subjective preference among pre-presbyopes (aged 20-40 years) with digital eye strain symptoms.

Participants tested four lenses: +0.50D, +0.75D, +1.25D, and a plano lens during near work tasks. According to the study findings, which lens addition was the least preferred by participants?

• 0.00D

• +0.50 D

• +0.75 D

• +1.25 D

• 21%

• 49%

• 68%

• 89%

7. The inter-pupillary distance (PD) of a single patient, known to be 68 mm, was measured by 54 registered practitioners in U.K. using a PD rule. What was the range of inter-pupillary distances (IPDs) recorded by the practitioners during the study?

• 67-69 mm

• 66-70 mm

• 64-71 mm

• 63-72 mm

Which factor was found to be the strongest predictor of patient preference for new spectacle prescriptions?

• Best distance visual acuity

• Ease of adaptation to a new pair of spectacles

• Quality of distance vision

• All factors are equally important

9. In one study, UK optometrists were asked their opinions on the following case:

A 30-year-old taxi driver has been wearing spectacles for 3 years and now wants a new pair. He reports no problems with his current spectacles. What was the most popular response from the optometrists regarding the new prescription in this case?

• Prescribe the new subjective prescription

• Prescribe a prescription midway between the habitual and subjective prescription

• Prescribe the same prescription as his current spectacles

• All answers were equally popular
