Vision Problems/Refractive Errors


Myopia is the medical term for "nearsightedness," a condition in which the eyes clearly see objects up close, but not in the distance. Myopia is usually an inherited trait and is oftentimes found in children between the ages of 8 and 12. Myopia less commonly manifests itself in adulthood. It is a misconception that excessive reading, computer use, and diet causes or affects myopia. Myopia is easily correctable with glasses or contact lenses. In some cases laser vision correction may be an option.


Hyperopia is the opposite condition to myopia. Instead of an ability to see near objects better than far, the hyperopic eye sees far objects better than near. Hyperopia is easily correctable with glasses or contact lenses, and laser vision correction is available in some cases.


Astigmatism is a distortion of light as it passes through the cornea. An astigmatic eye is not round, but shaped more like a football, causing a distortion or tilting of images. Astigmatism is correctable with corrective lenses and, in some cases, laser vision correction may be an option.


Presbyopia is an age-related disorder caused by a loss of focusing power in the eyes. Nearsighted people may need to add bifocals to their corrective lenses, and some people who have never had to wear glasses before may need to start wearing reading glasses. Some people with mild nearsightedness may only need to remove their corrective lenses to read or do close work.
