Myopia is also referred to as nearsightedness . It is a vision condition in which objects that are closer to the eyes are seen clearly, but objects farther away appear blurred. Nearsightedness occurs if the length of the eyeball is too long or the cornea (the clear front cover of the eye) has too much curvature. As a result, the light entering the eye isn’t focused correctly and distant objects look blurred.
Some research supports the theory that nearsightedness is hereditary. There is also growing evidence showing that it may be influenced by the visual stress of increased amounts of close work.
A common sign of nearsightedness is difficulty seeing objects that are far away like a movie or TV screen or the chalkboard in school. A comprehensive eye examination performed by Dr. Felton will include testing for nearsightedness. Dr. Felton can prescribe glasses or contact lenses that correct nearsightedness and make your distance vision clearer.
Hyperopia is also called farsightedess. It is a vision condition in which distant objects are usually seen clearly, but close ones do not focus correctly. Farsightedness occurs if your eyeball is too short or the cornea does not have enough curvature, so light entering your eye is not focused correctly.
Astigmatism is a vision condition that causes blurred vision due to the irregular shape of the cornea. An irregular shaped cornea or lens prevents light from focusing properly on the retina, the light sensitive surface at the back of the eye. As a result, vision becomes blurred at any distance.
