RP) this is a deterioration of my Peripheral vision and night vision (night blindness). there is no cure at this given time.RP conditions are progressive, but the speed and pattern of deterioration of sight varies from one person to another. For most people, the first effect of RP is the gradual loss of peripheral vision. This means that you can start to miss things slightly to the side of you or trip over or bump into things you would have seen in the past. Most people with RP eventually have a very restricted visual field, leaving only a narrow tunnel of vision.

Most people with RP retain useful central vision through their twenties, which means the ability to read and recognise faces is not greatly affected. By 50 years of age most people's central vision is affected to the extent that reading is a problem without the help of a magnifier.

Many people who have RP find the glare from bright lights and sunlight becomes an increasing problem. The retinal cells become less able to adapt to changing light levels and it becomes more difficult to use your vision when you move between a light and a dark room.
