10 Common Eye Diseases
Eye Disease #10: Cataracts
The lens in the eye helps us to focus on objects near and far. It needs to allow light to pass through freely so it is completely clear. As we get older, though, this lens can become cloudy, inhibiting our sight. This is called a cataract and is a fairly common problem among aging people. As well as being a result of aging, it can also be caused through injury.
If left untreated, the patient’s sight can be obscured to the point of making them unable to see at all. The good news is that this can be operated on. The cloudy lens can be removed and replaced with an artificial one that works just as well as the real thing. This should restore the patient’s sight completely.
