What’s So Special About Blue Light?

Eye Care Services Fargo NDAs technology becomes more integrated into our lives, eye strain and related conditions are being discovered more often during routine eye exams. If you poke around the menus of the most recent smart phones and tablets, you may stumble across a setting for a blue light filter. There may even be a few words about how the filter can reduce eye strain. What exactly is blue light, and how does it cause eye strain?

Blue Light 101

Light is energy that travels in waves, and the length of the wave determines the level of energy. Scientists have labeled each wavelength as a specific color, and when put together, it creates what is known as a “visible light spectrum.” The spectrum includes the light that can and cannot be detected by the human eye. The blue light sits right at the point where the human eye can no longer detect light. So, what does this have to do with our cherished devices? Consumer demand for jaw-dropping realism, complex graphics, and superb color motivated manufacturers to find ways to bring their devices to the top of the “must have” list, and blue light was the solution.

Why Blue Light Can Be a Pain

The information that you see on your computer or device screen may look stationary, but it is flickering at very high speeds, the level of which is undetectable by the human eye. The flickering, in turn, causes glare, but not the type that happens when sunlight hits the screen of the device. Rather, the glare is an “over brightness.” Your eyes do not have natural filters for blue light. Because of this, people who spend a significant amount of time on their computers and devices may develop eye strain, as well as macular degeneration and damage to the retina. Left untreated, these problems can cause vision loss.
