What does retinitis pigmentosa do to your sight?

ANSWER

The retina has two types of cells that gather light: rods and cones. Most forms of retinis pigmentosa affect rods first. These are around the outer ring of your retina and at work in dim light. You lose your night vision and ability to see to the side (peripheral vision).

Cones are mostly in the center of your retina. When retinis pigmentosa affects them, you slowly lose your central vision and your ability to see color.
