These children have the mental capacity to cope with the educational demands; however, they still have to encounter visual challenges gallantly. The World Health Organisation (WHO) defines a person with low vision as one who has impairment of visual 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 less than…
