Eye Conditions

The following is a list of common eye conditions. For information about cataracts, glaucoma, macular degeneration and diabetic retinopathy please see Eye Diseases.

  • Commonly called “lazy eye,” amblyopia can be treated successfully if detected early enough in childhood.
  • Astigmatism is a vision condition that causes blurred vision due either to the irregular shape of the clear front cover of the eye, or sometimes the curvature of the lens inside the eye. An irregular shaped front 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.

    Astigmatism is a very common vision condition. Most people have some degree of astigmatism. Slight amounts of astigmatism usually don't affect vision and don't require treatment. However, larger amounts cause distorted or blurred vision, eye discomfort and headaches.

    Astigmatism frequently occurs with other vision conditions like nearsightedness (myopia) and farsightedness (hyperopia). Together these vision conditions are referred to as refractive errors because they affect how the eyes bend or "refract" light.

    A comprehensive optometric examination will include testing for astigmatism. Depending on the amount present, your optometrist can provide eyeglasses or contact lenses that correct the astigmatism by altering the way light enters your eyes.

  • Red, swollen eyelids and crusty debris at the base of your eyelashes are signs you may have blepharitis.
  • AIDS or other diseases that affect your immune system can increase your risk of serious eye problems from cytomegalovirus (CMV) infection.
  • Are you bothered by red, itchy eyes? You may have allergies.
  • “Floaters” are usually normal and harmless. But if you notice a sudden increase in floaters or floaters accompanied by flashes of light, see your eye doctor immediately.
  • Also called farsightedness, hyperopia is a common vision problem that can cause headaches, eyestrain and trouble reading.
  • This eye disease causes the cornea to grow thinner and bulge forward in an irregular cone-shape. Treatment options range from gas permeable contact lenses to a cornea transplant.
  • Low vision is the term used to describe reduced eyesight that cannot be fully corrected with eyeglasses, contact lenses or eye surgery. The primary causes of low vision are eye diseases, but low vision also can be inherited or caused by an eye or brain injury.
  • Also called nearsightedness, myopia is a very common vision problem, affecting up to one-third of the U.S. population.
  • You’ve heard of high blood pressure, but what about high eye pressure?
  • If you have light sensitive eyes, you might be experiencing photophobia.
  • Pingueculae and pterygia are funny-looking words for growths on the surface of your eye.
  • This acute and contagious form of conjunctivitis is particularly common among preschoolers and school-age children.
  • Ptosis is a drooping eyelid. Surgery is usually required to correct this problem.
  • A detached retina is a medical emergency. Learn the warning signs of a retinal detachment and what you can do to avoid permanent vision loss.
  • These inherited disorders, commonly abbreviated as RP, cause progressive peripheral vision loss, night blindness and central vision loss.
  • This common problem is simply an infected lid gland. Learn how to prevent and treat styes.
  • This inflammatory eye disease can cause permanent vision loss if not promptly treated.
