What is Blue Light and is it Harmful?

Blue light is one of the several colors in the visible light spectrum. You may know them by the acronym ROYGBIV. Together, they make the white light you see when the sun, the main source of blue light, is shining. Fluorescent and LED light bulbs also give off blue light. Each color on the visible light spectrum has a different wavelength and energy level. Blue light has shorter wavelengths and higher energy than other colors. Research shows that there is a link between eye damage and short-wave blue light.

Between scrolling on our phones, checking social media, working on the computer, and watching TV, it is fair to say that we are exposed to blue light all day long. Blue light from electronics is linked to problems like headaches, blurry vision, eyestrain, dry eyes, macular degeneration, and cataracts. Blue light also affects your body’s ability to regulate melatonin production and can contribute to difficulty sleeping.

Functional Medicine Partners/Pain Relief Partners want to help you combat the issues related to blue light, reduce your eye strain and headaches, and help you get better sleep. We did our research and found a blue light protection product that we believe will really help!

Swanwick’s Day Swannies and Night Swannies are now available at the clinic. The specialized lenses in Day Swannies can block the most harmful part of blue light (98% at 400nm, graduating to 47% at 450 nm) reducing electronic screen glare but still allowing some “good” blue light in to help regulate the circadian rhythm and support mental alertness during the day. Night Swannies can block the full spectrum of blue light to help you optimize your sleep/wake cycle and get a great night of sleep.

Sleep is critical for high performance, but it tends to be the first thing neglected during busy, high-stress periods. Blocking out the harmful blue light can help reduce your eye strain and help you sleep better! Ask us for additional details!
