This is achieved by providing appropriate optical devices and special training in the use of residual vision and low vision aids, which range from simple optical magnifiers to high magnification video magnifiers. Low vision devices can be optical (telescope, magnifying glasses, magnifiers, etc.), non-optical (extra illumination, typo scope, books with enlarged text, writing guides, clock with large numbers, keyboard with large letters, etc.) and electronic device (Closed-circuit television (CCTV) or portable electronic devices).
