Can I use the same contact for both eyes?
MAY 10, 2020
If my prescriptions barely differ between each eye, can I buy a box of contacts for one eye and use them for both?
To get the sharpest vision in both eyes and lower the risk of eye strain, it is recommended to use the exact prescription recommended by your ophthalmologist. Wearing an incorrect prescription may impair vision, especially if you are under-correcting your dominant eye. Overcorrecting one eye can lead to symptoms of eyestrain including headache, fatigue, and blurred vision.
In some cases, though, ophthalmologists intentionally give a slightly lower prescription than measured in one eye to counteract the effects of presbyopia (age-related loss of near/reading vision). You should discuss your concerns with your ophthalmologist to see if there’s an acceptable solution.
