How Long Are Eye Prescriptions Good For?

Written By Lauren Anderson

Written By Lauren Anderson

Are you wondering if you have keratoconus?

Keratoconus symptoms generally start slowly. Your vision might gradually become blurrier, or lights may start to look strange at night. You’ll also probably find your glasses stop working as well as they should.

In this article, we’ll discuss the most common signs of keratoconus and talk about why it affects vision the way it does.

However, these symptoms could point to a huge range of conditions, so it’s important not to leap to any conclusions about what could be going on with your vision. Instead, speak to your eye doctor so they can properly diagnose you.
