Lens opacification, also known as cataracts, is a condition that causes the lens of the eye to become cloudy or opaque, resulting in blurred vision or vision loss. Cataracts are a common age-related condition, but they can also develop as a result of other factors, such as injury, certain medications, or medical conditions like diabetes.
The lens of the eye is normally clear and allows light to pass through, but with cataracts, the lens becomes cloudy and scatters the light, leading to blurred vision or difficulty seeing in bright light. Cataracts can also cause other symptoms such as double vision, difficulty seeing at night, and increased sensitivity to glare.
Treatment for cataracts typically involves surgery to remove the cloudy lens and replace it with an artificial lens. This surgery is generally safe and effective, and most people experience improved vision following the procedure.
In some cases, early stage cataracts can be managed with glasses or contact lenses to correct vision, or with increased lighting to improve visibility. However, cataracts will continue to progress over time, and surgery may eventually be required to restore vision.
Preventative measures that can help reduce the risk of developing cataracts include wearing sunglasses to protect the eyes from UV radiation, quitting smoking, and managing medical conditions such as diabetes that can increase the risk of cataracts.
