What You Need to Know
What is Blue Light? All the light that we see has wavelengths ranging from 380 nanometers (nm) on the blue end of the spectrum to about 700 nm on the red end. Approximately one-third of all visible light is considered high-energy visible (HEV) or "blue" light. Blue light generally is defined as visible light ranging from 380 to 500 nm. Take a look at the picture below to help you understand this. Blue Light is…. Good? Contrary to popular belief, blue light isn’t necessarily bad. We are exposed to it almost everywhere and it’s actually pretty important! We receive bluelight exposure from the sun, fluorescent lighting, LED lights such as those found in computer monitors, smart phones, tablets, and most TVs. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm, boost alertness, help memory and cognitive function and elevates mood. Early studies even show a deficiency in blue light exposure could contribute to the recent increase in myopia/nearsightedness. The Dark Side of Blue Light As we all know, it is possible to have too much of a good thing! It is important that we regulate when and how much blue light we are exposed to. Excess exposure to blue light can lead to the following consequences. Sore and irritated eyes Prolonged exposure to blue light can cause digital eye strain that manifests in sore or irritated eyes and difficulty focusing your eyesight. Retinal Damage Excess exposure to blue light can also damage retinal cells which can cause major vision problems down the road due to age-related macular degeneration. Sleep Issues Blue light expose up to 3 hours before bed can throw off our natural circadian rhythm, making it more difficult to fall asleep and lessing the quality of our sleep. At night, your pineal gland secretes melatonin, which is a hormone that makes you feel tired and go to sleep. Blue light, such as from the sun and your cell phone, however, inhibits melatonin production inhibits you from getting a full and restful sleep. Lack of sleep can be linked to a plethora of other issues such as depression, grogginess, and obesity. What can we do? The conclusion seems clear. Some blue light exposure during the day is healthy and beneficial. Prolonged exposure or exposure up to 3 hours before bed can have some pretty crazy adverse effects on your body.
