Cataracts are the cloudy patches that often develop in the lens of your eye. They can cause blurred or misty vision. Do not worry, they are very common and are treatable. Eye Lens: The lens is the transparent structure that sits just behind your pupil (the black dot in the centre of your eye). It allows light to get to the back of your eye (retina). As we age: In some people, cataracts develop in the lens as they get older. This results in some of the light not being able to reach the back of the eye. As we age these patches become larger and can start affecting vision. Many people with cataracts will eventually need surgery to remove and replace the affected lens.
Many signs of cateracts are missed as they do not adversly affect a person's vision. Whilst they normally develop on both eyes the degree in which they are affected can vary between eye lens or eyeballs. Small spots or patches where your vision has become blured or patchy are common symptoms. Cataracts is an internal complaint affecting the eye itself. There would be not teltale syptoms or redness or itching around the eye.
Cataracts may also affect your sight in the following ways:
Simple eye conditions
The eye is a precise image capturing device that relies on an image being formed on the retina by the focussing of light rays through the cornea and fine tuned by the internal lens. Given that the tolerances for good vision are extremely small and that these rely on the correct focussing power given the axial length of the eye all of which one would expect to be as variable as the size of any other part of our body it is a small miracle that many of us need no correction until in later life. When such a perfect fit is not present we end up with a need for optical correction.
Below is a list of symptoms of this condition and the other conditions that could cause them.
