Like a camera, the eye sees when light enters it. Inside your eye is a natural clear lens, much like the lens of a camera. It focuses the light rays coming through the pupil onto the retina at the back of the eye. The different parts of the retina collect this light and send a message to your brain, enabling you to see.<\/p>\n
For perfect vision the lens should be clear so that light can pass through it. Light enters through the cornea, passes through your natural lens and is focused onto your retina, resulting in clear vision<\/p>\n
When the lens becomes cloudy or opaque, light cannot pass through it. Cataract scatters the light rays passing through the eye, thus resulting in blurred vision. A cataract is a condition when the natural lens inside your eyes gets cloudy. Compared to vision with a clear lens, your vision with a cataract may look fuzzy, colors might be muted, and you may experience difficulty in reading signs while driving at night. The symptoms of cataracts are progressive and cannot be corrected with glasses or contacts. When symptoms become bothersome or limit your daily activities, it\u2019s time to consider treatment.<\/p>\n
The most common cause of cataract is degenerative changes due to the ageing process. With age, proteins in the natural lens degenerate, resulting in a clouded lens called a cataract. There might be other causes such as:<\/p>\n
If you have cataract, you may experience some or all of the following symptoms. <\/p>\n
