One of the most basic principles of enhancing vision is contrast;Our vision is improved when we enhance our contrast. When there is good contrast, things stand out more clearly. For example, if you eat white rice on a white plate its more likely that a visually challenged person would have difficulty seeing it. So if you use a blue plate or a dark-colored plate, then the white rice stands out. When there are steps to go to a different room, if the person is not familiar with the place, and the elevated step is the same color as the floor, then there is a higher chance that one can trip over or miss this step. To remedy this, if the floor is grey, then you put a bright-colored tape that contrasts with grey (neon yellow, white, etc) at the edge of the step so that it would be easy to detect that there is a change in the level of the floor. These are easy tips of how to enhance contrast at home.
One way to enhance contrast for visually challenged people is to wear filters. There are yellow, or amber lenses and different shades of amber. These can be sunglasses, or fit-overs (they fit over your glasses). When worn, they improve one’s vision almost always. When used for outdoors, they darken dark colors, but they don’t darken the light colors. When used for reading, it can darken the print on the page. It can also improve watching television.
Enhancing contrast is another easy way to maximize your visual potential.
