In general, an older person needs two to three times more light to see than a younger person, but people with some eye diseases may be sensitive to glare (Watson, 2001). Therefore, it is important to increase lighting without causing glare, which can be accomplished with lighting placement, choice of lighting, and glare elimination. Light can be aimed to illuminate the task at hand by using a gooseneck lamp. The type of lighting used is important. Incandescent light is commonly used in desk lamps but may not provide good contrast or color perception. Halogen provides a bright white light but generates a lot of heat. Fluorescent light is energy efficient but may be harsh and flicker annoyingly (Watson, 2001). Full-spectrum lighting is the closest to sunlight but is high on the blue light spectrum, which may result in glare. Glare can be controlled by covering high-glare surfaces such as tabletops with tablecloths, and windows with sheer drapes (Cole, 2003).
