Good Lighting Is Essential
For many people with low vision, increasing the amount and type of ambient light can greatly improve reading ability. If you know someone who is visually impaired, check the adequacy of the lighting in their home — particularly in their favorite reading areas.
Use the brightest light bulbs recommended for light fixtures. Purchase lamps with three-way sockets that allow the use of bulbs that can be increased to 150 watts for reading.
Natural sunlight is the best lighting for reading. Arrange furniture so the person with low vision can sit near a window for daytime reading. For artificial lighting, purchase "full-spectrum" light bulbs. These bulbs emit light that more closely mimics natural sunlight than regular incandescent bulbs.
Avoid harsh fluorescent lighting, which can cause glare — especially for anyone with low vision. Replace fluorescent desk lamps or kitchen lighting with halogen task lighting or full-spectrum bulbs for better comfort and visibility.
