There are conflicting reports about the effects of blue light on your eyes. Some studies claim potential damage to the retina by overexposure, while still others insist there’s no effect at all. Since so many of us spend a great deal of time exposed to blue light screens in the workplace, it’s become a significant issue for workplace eye health.
It’s important to note that the largest source of blue light comes from our largest light source: the sun! We’re exposed to blue light on a daily basis. We know that light is composed of an entire spectrum of color, as evidenced by the rainbow. The red light being slower and dimmer while the blue light is brighter and moves more quickly. Our technological screens, like TVs, computers, smartphones, and tablets emit a much smaller source of blue light than the sun. So why is there so much concern surrounding blue light and our vision?
We spend an exorbitant amount of time with our eyes glued to some type of blue light screen. In fact, over the last thirty years, nearsightedness has seen a dramatic increase of over sixty percent! This could be due to the correlating time frame of increased computer usage. The ultimate concern is that so much time staring at blue light may have some very negative effects on our eyes. Some symptoms reported by those with excessive screen use include:
The popularity of blue light glasses has led many to believe they are experiencing relief from these symptoms. While still, other professionals say it’s only a placebo effect. They hold to the fact that there is no real evidence of any negative affect from blue light, but that symptoms are merely from the way technology is used.
If you find yourself suffering from any of the previously mentioned symptoms, try some of the following solutions.
Further study is needed to determine any concrete evidence of blue light leading to retinal damage. But if blue light glasses and other aids seem to provide some relief to your symptoms, there is no harm in using them. They have only yet to be proven medically necessary.
To ensure good eye health, get your eyes checked regularly by an optometrist or ophthalmologist. After age 65 it is recommended that your eyes are examined every 1-2 years in order to catch any early signs of disease.
