Ask an Optometrist

by Sunny on February 14, 2012

Question: 

Why shouldn’t I wear someone else’s glasses if I can see clearly out of them?

Answer:

Eyeglasses prescription is highly individualized and unique, although in some rare instances, one’s prescription can identically match another’s.  If the differences are minimal, one can accommodate through the incorrect prescription and gain a subjective perception of clarity.

However, this can eventually lead to asthenoptic symptoms including visual fatigue, eyestrain, tearing and headache depending on the length of time other’s prescription is worn.  It can also lead to unnecessary overcorrection of one’s prescription once the brain becomes adjusted to other’s eyeglasses prescription.

The recommended prescription is the least amount of prescription that achieves the maximum clarity of vision in order to provide the visual comfort.  Without a proper determination of the individual’s correct prescription through a comprehensive eye examination, a subjective perception of clarity through someone else’s glasses does not ascertain the individual’s own optimal preservation of vision and ocular health.
