What is the treatment for refractive error that is best and has fewest side effects?

Depends on the cause: There are several ways to treat vision problems related to refractive errors (need for prescription correction). The easiest is to wear glasses. Contact lenses can decrease your need for glasses, but must be cared for regularly in order to prevent infections. Laser vision correction and lens replacement surgery are alternatives that can provide lasting glasses-free vision but are costlier. ...Read more

Can refractive error or poor vision improved by tablets?

No: There are no pills or eye drops to change your refractive error. Poor vision, however, can be for other reasons. See your ophthalmologist to make sure your eyes are healthy. ...Read more

Can eye exercises prevent or correct refractive errors?

Can eye exercises prevent or correct refractive errors?

Not really: Refractive errors are intrinsic to the eye structure and are best corrected with glasses, contact lenses or lasik. In some cases of early presbyopia or difficulty reading, reading glasses may be delayed a bit with accommodation exercises but inevitably patients will require reading glasses. ...Read more

Are there ways to avoid age-related refractive errors?

Are there ways to avoid age-related refractive errors?

Not really: You are probably referring to the hardening of the lens which occurs with age (presbyopia) which inhibits the ability to see at near unless near corrective lenses are worn. There is no way to avoid this universal condition of humans but your ophthalmologist can offer ways to compensate using proper eyeglasses and certain types of contact lens. ...Read more

How do I find out what my refractive error is?

Ophthalmologist: If you need to find this out to get glasses, you will need a prescription from your ophthalmologist. If you already own a pair of glasses an optical shop can tell you the numbers. The reading takes specialized instrumentation and you cannot find this out from things found in the non-optical environment. ...Read more
