Abstract
Low vision is a moderate to severe form of visual impairment wherein best corrected visual acuity varies from less than 6/18 to 3/60 in better eye. A low vision subject is potentially able to use his residual vision for execution of tasks of his interest. Low vision may be due to retinal diseases, glaucoma and corneal affections. The visual and allied stimulus carrying neurons including photoreceptors and retinal ganglion cells get affected, resultantly the low vision subject has various forms of visual disabilities including diminution of vision, reduced contrast sensitivity, altered colour perception, defective depth perception, deficient form vision and glare. Therefore, affected subject sees the world differently from a normal one. The article describes how different aspects of vision are defeated due to low vision. Various rehabilitation measures including magnification, modified reading text material, increased lighting, visual stimulation and coloured lenses have been utilized in a pursuit to improve entire seeing experience of a low vision subject. However more extensive and detailed studies are required in order to assess the usefulness of these low vision aids in improving different aspects of visual functions.
