Answer :
Final answer:
In the minus lens test, 16 clicks at a standard 0.25 D per click indicates a 4.00 diopters of accommodation amplitude for the right eye (OD). The correct answer is b) 4.00 D.
Explanation:
The minus lens test you're referring to is a way to measure the accommodative amplitude of the eye, that is, how well the eye can adjust to see clearly at different distances. In this test, a minus lens is added until sustained blur is achieved, at which point we can calculate the accommodation amplitude. Given that you add 16 clicks on the phoropter OD (right eye) at a distance of 40 cm before sustained blur occurs, and considering that each click usually corresponds to a power of 0.25 D, we can find out the accommodative amplitude of the right eye.
- 16 clicks x 0.25 D/click = 4.00 D
Therefore, the correct answer to the question 'Minus lens test: you add 16 clicks OD at 40 cm before sustained blur. What is acc amp OD?' is b) 4.00 D, which indicates that the right eye has an accommodative amplitude of 4.00 diopters.
