I have a question here. A friend of mine, she is of age 35 is detected of having cataracts. It is totally unexpected because she never complained of having any eye problems and all of a sudden she started to get a blurred vision about 3 months before and when she consulted her ophthalmologist he said that they are the initial symptoms of cataract. No one in her family had cataracts before. I did a little bit of research and what I found is that, the protein in our lens clumps together and creates a clouding effect, and forms a blanket which is called cataracts. But I also read that cataract is a disease that comes due to old age( http://www.c-care.ca/blog/home-care/four-common-vision-problems-among-seniors/ ). Is that so? Or can it happen to any person even when he/she has no history of eye problems.
