H25: Senile cataract

H25.1: Senile nuclear cataract

When the lens of the eye is cloudy, it is also known as a cataract. The lens of the eye is located behind the pupil. The pupil is a round hole in the iris. The lens of the eye is transparent and lens-shaped like a magnifying glass. It lies in a fixed, transparent capsule made of connective tissue.

The lens of your eye has become cloudy due to your age. With age-related cataracts, the clouding usually starts after the age of 50. The clouding typically increases over time. The symptoms depend on how cloudy the lens is. Mild cloudiness can cause blurred vision. Vision may be impaired in a half-light, in particular. You may react more sensitively than usual to bright light. Generally, the cloudier the lens, the worse the vision. Your near vision may still be rather better than your distance vision.
