What is vision rehabilitation?
Vision rehabilitation is a comprehensive and holistic approach for helping people to make the most of their existing vision. It involves teaching them how to cope with partial or complete blindness by making adjustments in their lifestyle and/or work routine to enable them to lead productive and relatively independent lives.
Rehabilitation is a combination of learning daily living and work-related skills, and the use of suitable low vision devices, along with professional counselling.
