What is a Cataract?
A regular eye lens is normally clear, allowing light to pass from the front right to the back, creating an image for your brain to process. When the lens becomes cloudy and light cannot pass through, this causes blurred vision. This type of cloudiness is called a Cataract. Most types of cataracts develop slowly and usually only in the later stages of an individual's life and can impair regular activities such as reading, watching the TV and driving. Cataracts are a natural process of ageing that cannot be avoided or prevented with medication but there are procedures that can help remove Cataracts.
