If you have been suffering from blurred vision with halos and glares for years, then there is a possibility that you may have an ocular disease called keratoconus. But, what is keratoconus?
Keratoconus is an eye condition in which your cornea (the clear front surface of your eye that is shaped like a dome) thins and bulges outward into a cone shape. Your cornea is responsible for focusing light into your eye, but if it changes its shape, it brings light rays out of focus. This results in blurry and distorted vision. Eventually, you will find it hard to perform daily tasks such as driving and reading.
