Definition of Low vision:
The WHO working definition of Low Vision (WHO, 1992) is as follows:

functioning even after treatment, and/ or standard refractive
correction, and has a visual acuity of less than 6/18 to light
perception or a visual field of less than 10 degrees from the point
of fixation, but who uses, or is potentially able to use, vision for
the planning and/or execution of a task”.

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.
