People should get their eyes checked because the early signs of some eye diseases are silent or vague, according to the Centers for Disease Control and Prevention. Also, a child may be too young to know that her vision is not as sharp as possible and may need corrective lenses.
Among the eye diseases that people may not notice developing are glaucoma, cataracts, macular degeneration and diabetic retinopathy, claims the CDC. Glaucoma results when elevated pressure in the eyeball damages the optic nerve. It is a leading cause of blindness and vision loss.
A cataract is a clouding of the lens of the eye, according to WebMD. The symptoms may be minor at first and are easily ignored. Vision gradually becomes more and more blurred, and the person may be bothered by glare from headlights or lamps.
Patients may also ignore diabetic eye disease, says WebMD. Patients may see "floaters" in their field of vision, or their vision may become blurry. Age-related macular degeneration is usually a slowly progressive disease where the macula is damaged, claims the National Eye Institute. The macula is the center of the retina that allows for accurate central vision. Finding these eye conditions early, with regular checkups, may save a patient's vision.
