In the post Increase brightness to reduce glare in your home or office only half the story of how to reduce glare was told. To reduce glare you may also reduce brightness (or do a combination of both – specific solutions to reduce glare depend on how it’s being produced). Here are a few examples of when and how you might reduce brightness to reduce glare in your home or office.
How to reduce glare
Glare is essentially a contrast in brightness. To reduce glare one should either:
- increase brightness (of the darker areas, when brighter objects contrasts with them)
- reduce brightness (of bright area – a source of light or its reflection in the field of vision)
- a combination of both; increase brightness and reduce brightness simultaneously
Reduce brightness to reduce glare
These are some examples of how to reduce brightness to reduce glare:
- Reduce brightness by better use of colors and surfaces. Use surfaces that absorb more light (rough surfaces of darker tones) instead of reflecting it (avoid shiny, polished surfaces, gloss electronic device screens, etc.). Correct use of colors and surfaces is particularly important when they are behind your computer screen (walls, office cabinets) thus increasing the glare on your screen.
- Reduce brightness of light sources in your field of vision. Use fixtures with opaque shade (this also disperses the light – see the next point). Position your computer screen so it doesn’t reflect light coming through a window. Make sure your reading lamp doesn’t reflect in the computer screen or other shiny surface. Turn down the brightness of your television or computer screen (remember, electronic display devices are sources of light).
- Reduce glare by dispersing the light. For both targeted and general lighting cover your light sources with translucent covers (a fabric shade on a lamp, light fixtures, a frosted glass globe). Make sure the cover fully covers the light source thus eliminating all undispersed light.
- Reduce brightness of general lighting. Reduce the number of light bulbs. Use a dimmer switch. Turn the 3-way bulb to a lower setting. Turn a light off to get rid of the bright spot. Pull down room-darkening shades to block outside light.
- Reduce glare by changing the color temperature of the light source. Avoid cool light (blue) in favor of warm light which is less likely to be seen as glare compared.
As stated in the previous post, to reduce glare for a person with photophobia / light sensitivity requires a lot more fine tuning than in the case of those without intolerance to light.
