Organizations like RNIB can guide them in selecting the correct equipment. One can start with readily available equipment like the ones that convert the text size to a word processor. A healthy working environment is crucial so that the impaired can easily communicate all their needs with the instructors.
Visually impaired people must get appropriate light and working conditions so that they can effectively use the vision they have. Learning technology is apt surroundings will enhance their learning. Glare-free lighting should be there to read and the screen should not be kept under direct light.
Depending upon the individual needs one can select the computers and their software configurations. The impaired must communicate all their needs to someone who is setting up the computer for them. Text size, font, and colors must be set accordingly. Contrast and brightness controls should be done on the monitors. Some users may prefer an anti-glare screen. The direction of light, the position of the window, and the height of the workplace must be arranged according to the individual needs. The importance of technology is immense for helping the impaired individuals.
