Refractive Errors
Refractive Errors Definition
Refractive errors are conditions in which the light passing through eye often loses focus. This is a cause for vision acuity. This condition is due to genetic or environmental factors, and the effects can either lead to blurry vision, astigmatism, myopia and hyperopia. The condition can be diagnosed by visual eye examination, retinoscopy and by the use of an automated refraction factor to measure the errors of eye focus. Treatment is by wearing prescription glasses, and contact lenses, as well as undergoing refractive eye surgery.
