The first sign of a cataract is usually blurred vision.

Cataract is a condition where the natural lens in your eye becomes progressively cloudy, impacting your vision and making it difficult for you to go about performing your daily activities.

Most forms of cataract develop in adult life and cause the lens to harden and become cloudy as you age. Although most cataracts are age-related, there are other types, including congenital (present at birth), drug induced (steroids), and traumatic (injury to the eye).

Cataract is also more common in people who have certain diseases such as diabetes, which tend to occur at an earlier age than those without the disease.

While cataract cannot be prevented, it can be treated by a surgical procedure commonly known as phacoemulsification, where the cloudy cataract lens is removed and replaced with an artificial lens implant.

If the amount of cataract is little and does not disturb your vision or your daily activities (e.g. driving or reading), it can be left alone.

Eyeglasses may help at this stage to allow you to see better. If using eyeglasses does not help, and the cataract interferes with your vision, your eye doctor may suggest doing a cataract surgery.
