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

When it becomes very large (anisometropia), it becomes more difficult to fuse and can result in amblyopia. Contact lenses tend to be better tolerated in people with large differences than glasses. ...Read more
