Cataract

Time to ask yourself:

  • Is your vision blurry or foggy?
  • Do colors appear dull or muted?
  • Are your glasses no longer working?
  • Does sunlight or other light seem overly bright or glaring?
  • Do you have decreased night vision or see halos around lights?

If you experience one or more of these symptoms, you may have cataracts, a clouding of your eye’s natural lens that affects many of us as we age. Cataracts are the leading cause of visual loss in adults 55 and over. Fortunately, we live in a time when correcting cataracts is relatively simple and the results can be extraordinary. With today’s advances, some patients enjoy the best vision of their lives.

How We See

Our eyes work just like a camera. When we look at an object, light rays reflect off that object and enter our eyes through the cornea. The lens behind the cornea focuses the rays onto the retina which, in turn, converts the rays into electrical impulses that travel through the optic nerve to the brain. The brain converts the
electrical impulses into images. Seeing depends on this entire chain of events. But seeing clear, focused images depends largely on the lens.
