hi there,

Low Vision is a state that involves a minimal capability to see (predominantly central vision) which cannot resolve by the traditional eyeglasses, contact lenses, intraocular implants, or corrective surgical procedure. The common causes of low vision are the following:

Macular degeneration- the most common cause of low vision which involves damaging of the person’s central vision

Aging- as we got older our capability to visualize become poorer, yet there is no specific age when will be a person be inflicted by low vision problem

Congenital Deficiency

Disease (Diabetes)

Other eye diseases

Hence, low vision cannot be improve by the traditional method, a person who has low vision rely on using low vision devices. These low vision devices are categorized into two groups: optical low vision devices and non- optical vision devices. Optical low vision devices use one of the many types of lenses to enhance visual ability. This includes: magnifying devices and closed circuit television. While non- optical devices are devices which can bring closer images to the eyes. Few are larger printed items, larger illuminated watches and clocks, instruments that provide voice instruction, and instrument that provide voice information.
These low vision devices aid the improvement of the visual ability of millions of people everyday.


Hope this can help
