An expert warns that office lighting is not suitable for white desk

A senior official from the leading ophthalmology charity warned that white-collar workers should not sit at white desks under modern office lighting.

Keith Gordon, vice president of the Canadian National Association for the blind, said it would be a prudent practice to keep away from the white desk and to reduce the damage caused by excessive exposure to blue light.

The effect of the white surface is "similar to the effect of the sun shining on the snow for the skiers."

"The white desk will reflect anything out of the computer, so you get a double blow. If you sit on a white table and have a fluorescent lamp, it will be reflected from the desktop to your eyes. I suggest that people use dark black desks. "

"Normally, because the lights themselves don't have too much concern, people spend hours looking at these screens, so there's a worry that if you spend a day watching a computer monitor with so much light, it's a long-term damage to your eyes."

However, Keith Gordon stressed that it is worth noting that the direct link between long-term exposure to blue light and human retinal damage has not been fully confirmed.

Gordon recommends that office workers use software to reduce exposure to blue light, such as free f.lux filter applications, which can be installed in computers and mobile devices to adjust the emitted light according to a day's time. In addition, many computers and smartphones now have a mode of blue light reduction.

Employees can adjust the level of blue light from the screen by reducing the brightness of the screen or changing the contrast by switching to the black bottom white word.

Gordon says security managers can limit the amount of blue light generated by the overhead lighting. He urged facility managers to avoid the installation of cold white or blue white fluorescent lamps and to designate coatings to produce less blue light and warm white light. He also recommends a rapid replacement of flickering fluorescent tubes, because the broken tubes will send out more blue light. (Editor: LED network James)
