The screen

Settings for text sizes, fonts and colours can be used to alter the appearance of the screen and to increase its legibility. The monitor controls can be used to alter contrast and brightness. Apple Macintosh and PCs using Windows have built into their system a range of adaptations to help users with visual problems. A larger or higher quality monitor may be easier to see. An anti-glare screen may be required for some users. The working environment is important, taking into consideration such factors as monitor height, position of windows and artificial light.
