Modifying a Home for Macular Degeneration

October 20, 2016 By Karen Koch

Home Modifications for Persons with Macular Degeneration

Age-related macular degeneration (ARMD) is a disease that affects the macula, the center of the retina, and is the leading cause of vision loss in people over 60 years old (Lewis, 2003). The macula gradually deteriorates causing the central vision to be lost but the peripheral vision still intact.

According to Lewis, here are 3 interventions to take place in a home environment:
1. Lighting is crucial to improve visual functioning for people with Macular Degeneration. Whether it’s brighter overhead lighting in a kitchen to perform cooking, task lighting for reading/writing, or increased lighting on stairs to help prevent falls, extra lighting is essential. LED lights are recommended for people with macular degeneration

2. Contrast can increase the visibility of objects. Examples include: bed skirt color different than the comforter, adding lighting under overhead cabinets, painting handrails for stairs. See ideas here.

3. Size: magnification devices will help an object appear larger.

 The macula has the highest concentration of cones which provide color vision. Therefore, the degeneration of the macula results in damage to the cone color cells in the eye. People with ARMD can still see colors but color perception weakens overtime. According to the American Optometric Association, most people with color vision deficiency have difficulty differentiating between shades of reds and greens (most common) and blues and yellows (less common).

A couple more facts to know when designing for someone with macular degeneration:

  • LED lights are recommended over incandescent light bulbs:  Since sunlight is a factor in macular degeneration, lamps that mimic sunlight can have a negative effect on the eye. A significant factor is the spectrum – the different colors that make up the light. The colors of the visible spectrum are the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet. The low energy red through the moderate energy violet are not harmful and are necessary for vision.  However, high energy ultra-violet light, mostly UV-B, is responsible for damage to materials, skin, and eyes. Eliminating UV-B from man made light sources is desirable and very prudent for lighting used by individuals over 40.  With new technology such as LED (Light Emitting Diode) light sources, it is possible to make a lamp that is tailored to people with macular degeneration. LEDs designed for reading lights have no UV and extremely low IR (Infra Red) emissions. 
  • Use a yellow color background to increase visual perception of objects.  Yellow backgrounds seem to be preferred by most of healthy and AMD eyes. This preference may be modulated by factors such as the yellow-blue vision processing channel and/or luminosity differences produced by selectively transmitted light.
We are in the process of modifying a home for someone with macular degeneration, any other suggestions would be helpful.  Please comment below.
