As the U.S. population ages, 30 million people are expected to be diagnosed with this condition by the year 2020.
There are many symptoms and signs you can look for.
At first, your vision will only be a little blurry.
You may start to see more glares from the sun than before and colors may not appear as bright as they were before.
There are different types of cataracts and they will all affect how you may see things differently.
Now you may be wondering, what causes them?
The lens in your eye is very similar to the lens in a camera. The lens in your eye is made mostly of protein and water and it is arranged in a way that keeps the lens clear, in return your vision being clear.
However, as you age, some of the proteins may begin to stick together in the eye. Over time, this will become a cataract. It may grow bigger and cloud the lens, which is what makes it hard to see.
Nobody really knows why your eyes change as you age, but different studies have shown that a few things may be associated with the development of cataracts.
