Why have i had a blurry eye for half a day?

Question

Today, I've had a blurry eye for around 7 hours. I occasionally have a blurry eye that lasts for 1 hour, but this is the first time its lasted for 7 whole hours. Do I need glasses or will it pass?

Answer 1

This depends on your age and your health.  I doubt that it's an accommodation problem as another poster mentioned because that generally occurs in both eyes, not one.  Does it occur when you first wake up and then gets better or does it come on later in the day?  Unfortunately, without more information, I can't offer much help.

Answer 2

You may have an accomodation problem. In some people the lens of your eye that "zooms in" for close work goes into spasm, and doesn't relax again when you look into the distance. See if this happens after doing a lot of reading. If it recurs, it's definitely worth going to see an optometrist.

EDIT: Dear Eye Doctor (below) I have an accomodation problem in one eye.
