It's a matter of time: Know the symptoms of a cataract

Cataracts are fairly common, with some experts saying pretty much everybody will get them eventually -- it's just a matter of living long enough. Cataracts occur when the lens of the eye becomes cloudy, and then obviously it's harder to see clearly. Seeing at night is more difficult, colors may seem faded, there may be "halos" around lights, and vision in general may appear cloudy or blurred.

Thankfully, cataract treatment is easy and fast with today's technology. A simple surgery to replace the lens in the eye can be done, usually within an hour and without any hospitalization. But the single best thing you can do to help prevent (or at least "put off") the development of cataracts is super simple: wear sunglasses.
