Blue Light Glasses
Updated: Dec 5, 2020
Due to the rapid spread of COVID-19, many schools across America have decided to go online for at least the fall semester. This will inevitably lead to a rise in the daily average of many students’ screen time. Screens emit blue light, which can cause eye strain, headaches, and dry eyes. It has also been proven that blue light sabotages your sleep schedule by messing with your internal clock, making it harder to discern when to be awake and when to go to sleep.
Consequently, the number of people investing in blue light glasses has gone up, but what exactly are blue light glasses? According to HealthEssentials, blue light glasses have specially crafted lenses that either “block or filter out the blue light given off from digital screens.” They are supposed to protect your eyes from glaring blue light and lessen headaches, dry eyes, eyestrain, sleeping issues, and other detrimental side effects that come from being in front of a screen for prolonged periods of time.
Clayton Valley senior Isabella Castaneda has been using blue light glasses since last school year, and says that they have helped with her headaches and quality of sleep. “I thought they were quite effective and helped with all of my headaches while I had my concussion...my quality of sleep improved even just from wearing them while I was on my computer.” She also mentioned that using blue light glasses has helped her to focus on her screen for longer periods of time.
So are blue light glasses worth the hype? Answers from experts are quite varied. For instance, the American Academy of Ophthalmology says that eyestrain and other eye issues yielded from looking at screens are not linked to blue light, but rather to how long you are in front of a screen. “The symptoms of digital eye strain are linked to how we use our digital devices, not the blue light coming out of them,” says the AAO.
Other eye professionals, however, say that investment in blue light glasses can be quite beneficial. Senior optician Greg Rogers claims that his clients have seen improvements in their screen-induced maladies and quality of sleep after they started using blue light glasses. His staff recommend that if you spend six hours or more in front of a computer, blue light glasses may be a good investment.
Despite mixed opinions on the effectiveness of the glasses, most opticians agree that blue light definitely meddles with your quality of sleep, and that you should not be in front of any screen for at least two hours before going to sleep. However, if you typically type last minute essays before bed or scroll through social media late at night, investing in blue light glasses could help with your quality of sleep.
