Living with Retinal cone dystrophy type 1

An inherited eye condition affecting the cells that help with seeing color and fine detail, with sensitivity to light.

Understanding Retinal cone dystrophy type 1

Retinal cone dystrophy type 1 is an inherited eye disease that affects cells in the eye that help people see color and detail.

People with this condition may have trouble seeing clearly, be sensitive to light, and have trouble telling colors apart. They usually do not have problems seeing in the dark or losing side vision. There are different types of cone dystrophy, and some affect the center of the eye more than the edges.
