Cataract is a condition in which the eye lens turns cloudy that affects vision. It is mostly found in older people. As we grow older, the proteins present in our eye lens start breaking down. Due to this, the lens fails to send clear images to the retina. An opaque area is formed on the lens that interferes with your vision. It is the main cause of blindness in people above 50 years. According to experts, each year nearly 3.8 million people lose their eyesight due to cataract in India while globally the incidence figure stands at about 5 million
Main Causes of Cataracts
Usually, cataract occurs due to age factors and develops gradually. However, there could be many other reasons that can affect a young person with this eye disorder, such as:
➲ Family history of cataract
➲ Drinking & smoking
➲ Diabetes
➲ Exposure to Ultraviolet Radiation
➲ Certain medications or long-term use of steroids
➲ Radiation therapy
➲ Eye surgery or injury
➲Trauma

Diagnosing Cataract
Ophthalmologists conduct a comprehensive eye exam to diagnose cataract in a person. Slit-lamp exam, retinal exam, refraction and visual acuity test are some tests that help them in detecting cataracts
