Low light

Too much vergence

Homework Answers

Answer #1

When our eyes are forced to accomodate (focus) for extented periods of time, this causes strain in the eyes as the ocular muscles fatigue. Working in low light does not affect the vision but it puts strain on the eyes as the eyes have to focus harder on the objects in the dark. Vergence is the movement of the eyes in opposite directions to put an object in the center of the retina in both the eyes. When too much vergence is needed, the eyes experience fatigue and strain.

Hence, the correct answer is 'all contribute'.
