Correct lighting is one of the most important adaptive products for people with low vision. Adequate light can often be as effective as a stronger prescription. While it may be difficult to control overhead or room lighting, proper task lighting can provide maximum illumination without glare.
Task lighting may be in the form of desk or floor lamps with correct wattage bulbs and adjustable arms to help focus the light directly onto the task. Some lamps also include illuminated magnifiers. The ideal lamp should have a flexible spring arm and a reflector shade.
Contrary to popular belief, high-intensity or fluorescent bulbs with a light source that emphasizes the blue end of the spectrum do not relieve symptoms, particularly if glare is the complaint. An incandescent or fluorescent bulb that emphasizes the yellow-red end of the spectrum is a better choice, and many standard bulbs are readily available.
An understanding of the importance of illumination control at home, at school, or in the workplace is critical for those who work with patients who have low vision.
