What is a Cataract?
A cataract, although many people believe it to be a film or growth over the eye, is actually a clouding of the eye's natural lens which is the part behind the iris responsible for focusing light. It stops clear images from forming by creating a fog.
Usually as part of the natural ageing process, this clouding develops when proteins in the lens clump together. It scatters and blocks light as it progresses and enters the eye, leading to vision that's blurred and dimmed. This gradual change significantly impacts the ability to read, drive or recognise faces for millions of people with cataract surgery allowing for this lost clarity to be restored.
