The illustration shows the top lens as being clear while the bottom lens shows clouding because of a cataract. The clouding is similar as looking through a dirty car windshield, everything appears hazy, unclear and less saturated. Inside of our eyes, we have a lens that refracts light rays that come into the eye to help us obtain a clear image. The lens should be clear for best possible vision.
The majority of cataracts develop gradually. Thus the presence of changes in vision is not noticed at first.
Below are progressive changes that may occur with a cataract:
- Blurry vision
- Double vision (seeing two images instead of one)
- Sensitivity to light
- Difficulty with night vision
- Requiring additional light when reading
- Unsaturated colors seen either as faded or yellow.
