While there can be other contributing factors, the formation of cataracts is a natural part of the ageing process; just like greying hair and the need for reading glasses. Cataracts are a very common condition that creates cloudy areas within the lens of your eye. As we get older the lens inside our eyes changes and becomes less transparent. You may still be able to see but your vision is blurred and not as sharp as it once was. Much like when a cloud passes over the sun; it is still daylight but vibrant rays of sunshine are unable to get through. This cloudy vision will continue to develop until it starts to interfere with your everyday life, making thing gradually harder to see.
