Why glare occurs in cataract?

Why is there glare in cataracts?

A cataract can occur in either or both eyes and most cataracts are related to aging and, therefore, are very common in older people. Halos and glare can be caused by eye problems that keep the eye from properly focusing light onto your retina (the thin lining located in the back of the eye).

How do cataracts reduce glare?

The easiest way to cope with cataracts and glare is to limit the light coming into the eye. Wearing a wide-brimmed hat, wearing tinted glasses or sunglasses with a UV filter to protect eyes from harmful UV rays can reduce glare, helping with light sensitivity.
