For everyone else who has some residual vision, there may be aids or techniques to help them make the most of the sight they have, an example of this might be someone with a central vision loss learning to use the peripheral vision.
Sight loss is caused by a huge variety of different conditions, some of the most common are Glaucoma, Macular Degeneration, Diabetes, Cataracts and Retinitis Pigmentosa.
There are many resources in and around Staffordshire to help with travel, entertainment, leisure, training and employment.
