An estimated 22 million plus Americans age 40 and over experience cataracts. World-wide, cataracts are the most common cause of vision loss and is the primary cause of blindness.
When a cataract first develops it may have little effect on your vision, but as it grows larger, you may notice that your vision is more blurred than it used to be. While night driving, oncoming headlights glare more than they used to, and colors may not appear as bright as they used to. The symptoms of cataracts vary depending on the type of cataract you have.
Those who develop nuclear cataracts may experience something called “second sight”, a temporary improvement in their near vision at first. That improved vision will unfortunately disappear as the cataracts worsens. Subcapsular cataracts may not produce any symptoms until they’re well developed. A Cortical cataract’s effect on visual function varies greatly, depending on the location of the opacification relative to the visual axis. One of the most common symptoms of cortical cataracts is glare from intense light sources, such as car headlights.
When cataract symptoms begin to appear, your optometric physician may prescribe new glasses, strong bifocals, magnification, appropriate lighting or other visual aids. When your cataracts have progressed enough to seriously impair your vision and affect your daily life, you may consider cataract surgery, which nowadays is simple, relatively painless and very successful in restoring vision.
