Cataracts are a part of the natural aging process. Over time, the cells in the natural lens of the eye become more opaque and cloudy. There are many different types of cataracts – all resulting in changes in the lens and blurry vision. Some patients compare it to looking through a hazy fog, or shower door. Lifetime exposure to UV light, certain drugs, environmental toxins, and smoking can all cause cataracts to progress faster. Once they have developed, the only treatment is a surgical procedure. Cataracts should be removed when they are advanced enough to cause visual limitations, prevent adequate examination of the eye, or cause other eye diseases like glaucoma or inflammation.
