A difference of 400 degrees between my left eye and right eye!?

Question

My right eye is 125, left eye is 525. Is this lazy eye? What do i have to do to correct it? Will laser surgery help?

Answer 1

Lazy eye is defined by visual acuity wearing glasses, not by the degrees of prescription so we can't tell if it is lazy eye.

What did your eye doctor recommend? Glasses or contacts or laser surgery could be all that you need; if one eye is lazy you may also need to patch or do exercises.

Ask your eye doctor for advice specific to you.

Answer 2

You're missing a couple of decimal points:
that's almost certainly 1.25, and 5.25.

Since the normal "step", increment, in a prescription is 0.25D, yes 4.00 is still a considerable difference: 16 "steps"

You don't say whether the Rx is + or -, and that makes a difference to the lazy eye part.
The difference itself doesn't make for a lazy eye but, especially if it's a longsighted (+ve) Rx which you were not given when very young, there's a good chance that your brain will have had trouble using both eyes, and to avoid double vison or eyestrain, wil have concentrated purely on the eye with the 1.25 Rx, leaving the other eye undeveloped (amblyopic, lazy)

If the Rx is -ve this is less likely, as the brain could have used one eye for distance and one for closework, and they would probably both have developed normal nerve function, though possibly at the expense of being able to use the two eyes together: a probable strabismus or squint, but no lazy eye.

Laser surgery is one of the options to balance out the refraction, but that would not help the sharpness of vision in an eye that is lazy,
and having only one good eye is a counter-indication to laser surgery, because there are some risks.

What you have to do depends on your age, what vision you get with the Rx in place and whether the RX is + or -.

You may not even need glasses, or you could benefit from a correction and intensive vision therapy.
