Question

How do you measure accommodation?

Hint:

The near point test is an easy way to measure accommodation, but dynamic retinoscopy offers a more detailed and precise evaluation.

Answer 1

Step 1: Methods for Measuring Accommodation.
Accommodation can be measured using various techniques, including:
1. Near Point Test: The near point test is a simple method where the individual is asked to focus on a target object that gradually moves closer to the eye. The point at which the individual can no longer focus clearly is recorded as the near point. The reciprocal of the near point distance gives the accommodation in diopters.
2. Dynamic Retinoscopy: This method uses a retinoscope to measure the reflex of light off the retina while the individual is focusing on a near target. The accommodation is assessed by noting the change in the light reflex as the individual accommodates.

Step 2: Conclusion.
Both methods are effective in measuring the accommodation ability of the eye, with the near point test being the simplest and most commonly used.
