Choosing Lighting That Works for Your Vision
By Takeshita, Bill; Vision Access, Vol. 15, No. 4Publication Date: Winter 2008
Article discusses indoor lighting for people with low vision. An overview of the physics of light is presented and terminology for describing light-fixture brightness, electricity usage, and temperature is defined. Common types of indoor lighting are described including incandescent light bulbs and the more modern, energy efficient, and longer-lasting compact fluorescent bulbs; low-voltage halogen bulbs, which produce a very bright light and render colors accurately; and light-emitting diodes (LEDs), long-lasting, energy-efficient lights for use in table and reading lamps. The role of color in some lights is discussed, especially as it applies to people with corneal disease, cataracts, and retinopathy, who may be bothered by lights generating too much blue light which for them can cause glare. Also mentioned is the need of very bright lighting by people with retinitis pigmentosa and glaucoma, and the preference for dimmer lighting in living areas by people with macular degeneration and diabetic retinopathy. Specific lighting recommendations include compact fluorescent light bulbs or recessed lights for general lighting, fluorescent bulbs for the kitchen, track lights with low-voltage bulbs above work areas, desk lamps with a fluorescent of LED bulb for reading, and the installation of track lights with low-voltage halogen bulbs for closets.
