When my eyes water, my vision improves?

Post

In a week, my parents are taking me for a eye check-up. I think I might be getting glasses!! Besides that, whenever I yawn or something like that and water comes towards my eyes, somehow my vision is almost at 20/20! I do not understand. Is the light reflecting at my eyes differently

Hey Gurvir.. Tears flowing during yawning is common. It's not a disease al. After crying, you feel like your vision is good. But there's nothing like that. Do you have tears on your eyes, when you watch tv? If eyes, it is a symptom of some of the eye disorder. Visit an opthalmologist soon.

Tears act like a lens in front of the eye so they temporarily improve your vision.  It is about the way light refracts though water - see a physics website.

If you do get perfect vision with tears its not likely you will need a very strong perscription. Suggest if they do say you need glasses after the test you wait and order glasses at another time. Decisions on frames are quite expensive and its best to make them fresh. Eye exams tend to be long and boring especially the first time and you're less likely to make a good decision. You can get glasses made up anywhere although there are advantages to getting them done at teh eye doctors because they will do all the adjustments. Have a think what you would like , maybe take a friend along to help you choose.
