As we age, many of us hear the phrase, "You have cataracts," from our eye doctor. Cataracts are a common, vision-impairing condition caused by a clouding of the eye's natural lens. This issue cannot be corrected with glasses, contact lenses, or procedures like LASIK.
The good news is that modern cataract surgery can not only restore vision lost to cataracts but often reduce the need for glasses altogether.
