Using colored lights (such as pink, peach, or yellow) often creates visual comfort for some, while enhancing the contrast of the task at which the person is looking. Other kinds of lights include halogen, Chromalux, fluorescent, and a number of others. The kind and color of the light is dependent on the task itself and the person's preference. Move lamps close to your work. To help avoid glare, use an adjustable lamp and position the lamp to the side, rather than directly in front of you. Many people find it helpful to have lamps on both the right and left sides -- that will eliminate shadows. When writing, to prevent shadows, place the lamps on the opposite side of the hand being used. Locate the bottom edge of the lampshade just below eye level.
To reduce glare, cover bare light bulbs of all types with shades. Soften bright light from windows with coverings like blinds or sheer curtains. Also, position the chair and table so you don't have to look directly at the light coming from the window. To further reduce glare, cover or remove glossy surfaces such as floors and table tops. Glossy paper can increase glare, so try to use matte paper when reading or writing.

In hallways and stairways, provide generous amounts of light and position it so that it shines on the walls, floors, steps, and railings. Keep all rooms evenly lit. It is difficult for your eyes to adjust from bright light to low light, so if you keep all rooms well lit, it will be more comfortable to walk from room to room. Try not to walk from a brightly lit room immediately to a dark one.
