How is an error of refraction (EOR) treated?

Eyeglasses or contact lenses are the most common methods of correcting refractive errors. They work by refocusing light rays on the retina, compensating for the shape of your eye. Refractive surgery is also an option to correct or improve your vision. These surgical procedures are used to adjust your eye’s focusing ability by reshaping the cornea, or front surface of your eye.
There is not adequate scientific evidence to suggest that eye exercises, vitamins or pills can prevent or cure refractive errors.
Eyeglasses Wearing eyelasses is an easy method to correct refractive errors. They can also help protect your eyes from harmful light rays, such as ultraviolet (UV) light rays. A special lens coating that screens out UV light is available. Glasses or goggles made of protective lens material (polycarbonate) should be used for sports and all hazardous activities. All children and adults who have one poorly seeing eye should wear protective polycarbonate lenses at all times to protect their “good” eye.
Bifocals are eyeglasses used to correct presbyopia. They have a correction for reading on the bottom half of the lens and another for seeing at a distance on the top. Trifocals are lenses with three different lens corrections in one set of eyeglasses.
If you don’t need correction for seeing at a distance, you can receive a prescription for reading glasses or buy them over the counter to correct presbyopia.
No exercise or medication can reverse presbyopia. You will probably need to change your prescription from time to time between the ages of 40 and 60 because your lens will continue to lose flexibility.
Contact lenses There is now a wide variety of contact lenses available. The type best suited for you depends on your refractive error and your lifestyle. If you want to wear contact lenses, discuss the various options with your ophthalmologist.
You may have heard of a process called orthokeratology to treat myopia. It uses a series of hard contact lenses to gradually flatten the cornea and reduce the refractive error. Improvement of sight from orthokeratology is temporary. After use of the lenses is discontinued, the cornea goes back to its original shape, and myopia returns.
Refractive surgery Refractive surgery is covered in another section. See “What is refractive surgery”.
