|The cause of such impaired vision may be an eye injury suffered during an accident, or eye disorders like glaucoma or age-related retinal diseases. Vision loss suffered so, cannot be regained and medical help and rehabilitation emphasizes on preserving and utilizing the residual vision to the fullest potential. A combination of additional aid from low vision devices and suitable modifications in the environment the person lives in, is the normal approach to treatment.
Low Vision Aids
Magnifiers:The simplest low vision aids that you can provide the visually impaired are magnifiers. They are thick lenses that magnify objects and text, and are available in varying powers. For the aged or people with shaky hands, magnifiers with a stand are helpful while reading. There are also magnifiers with illumination facility to make the text brighter. One can also use a portable video magnifier or a pocket magnifier while shopping to see small print on price tags and instructions.
Text and writing guides: Cheque writers, writing guides and signature guides are designed to help the vision impaired sign on cheques and documents. Large print versions of books are helpful to those who love to read. Bold fibre tip pens or marker pens help to improve contrast and the legibility of writing and are recommended for children suffering from low vision.
Computer software: While using or working with computers, the vision impaired can use computer softwares that magnify text on the computer screen and even read out the words that appear on the screen. Cameras placed in a video magnifier can be attached to TV or computer in order to make it easier to read newspapers and bills. With patience, one can read the magnified letters on screen easily.
Multicoloured keyboard or Clevy keyboard or a keyboard which has large font keys also helps.
Electronic devices like the Clear Reader can take a picture of the text and read it out in some languages. The text can also be stored in a pen-drive!
