What are Myopia and Hyperopia?
Myopia and Hyperopia are terms for near sightedness and far sightedness. Hyperopia or farsighted ness is a visual condition where objects in the distance are are able to be seen but objects that are close are blurred Causes and Symptoms: Ideally, light that enters the eye is refracted by the cornea which is the clear covering on the front of the eye and is also refracted by the lens, coming to a sharp focus on the retina at the back of the eye.Hyperopia occurs because the eye is too short for the corneal curvature and the light that enters the eye comes to a focal point behind the retina causing blurred vision. Headaches can result from such a condition as well as fatigue, eye strain, red eyes, accomodation disfunction and trouble with eye allignment. Treatments: Hyperopia or far sightedness can be corrected by laser vision correction, glasses or contact lenses.

Myopia is the medical term for near sightedness. More that 70 million people in the US are myopic. Myopia occurs when the eye is too long for the cornea’s curvature. The term near sightedness means you can see near objects clearly without glasses but objects further away are blurred. Light rays entering the normal eye come to a sharp focus on the retina whereas in the case of the near sighted eye, the rays fall short of the retina producing a blurred image. Myopia or near sightedness can be corrected using laser vision correction, glasses or contact lenses. Find out more about Myopia by visiting American Optometic Association websites.
