The lens is mostly made up of water and protein and this is arranged in a precise regular way that keeps the lens clear, allowing light to pass through. As we age, the protein elements generally start to cluster together causing the lens to become cloudy. Over time, the protein changes result in complete clouding of the lens, eventually making it difficult to see.
At first, your cataract may have little effect on your vision. Over time the vision can become blurred and not improve even with new glasses. The longer the cataracts are left to develop the more severely they can affect your vision.
Do get checked for cataracts if you experience:
Cloudiness or mistiness
Faded or washed-out colours
Dazzling glare from bright light and light sensitivity
Dazzling glare from bright light and light sensitivity
Repeat changes in glasses
Double vision
