Patient discussion about sight

Q. What age does eye sight stabilizes? I was just wondering at what age does your eye sight usually level off and stop getting worse? Any ideas much appreciated!

A. It will stabilize in a few years-age of 26-27.That is the average age people perform lasik surgery.
It is also the age the eye is fully grown.
Don't worry it will not get much worse maybe about -0,75.
Take care

Q. What can you do to make your eye sight better? My eye sight isn’t that great. Is there anyway to improve it, like eating certain foods or drinking certain drinks?

A. There is something called the Bates Method. It is a combination of relaxation and exercises with the eyes. Depending on the problems you have with your eyes it may help. Do an internet search on Bates Method and you will get some info on it and a couple years ago I actually found a place I downloaded a description of some of the exercises.

Q. My vision is blurry and I see zigzag lines, what is it from? Every now and again, usually after sitting a few hours in front of the computer or not sleeping enough at night, I start getting blurry vision. I see zigzag lines in front of my eyes and it can take sometimes an hour to go away. What is this from?

A. It sounds like you have a migraine. A migraine that comes with blurry vision and zigzags (an aura) is called a classic migraine. The aura of migraine typically lasts from 20 minutes to an hour. Some patients have prolonged aura symptoms that can last hours to days. The aura also typically ends before the headache itself begins. When migraine aura symptoms are prolonged or last into or through the headache phase these types of migraine are commonly referred to as complicated migraines.
