Does it seem like everyone is talking about blue light these days? There’s a reason for it. If you’re reading this on one of your screens (smartphone, laptop, tablet), you’re exposing your eyes to blue light now, though that might be a bit simplified. Blue light is just one color on the light spectrum that we’re exposed to on a daily basis. Even the sun and indoor lights have some level of blue light, it’s just a matter of figuring out how to manage it. At Invision Optical, we vigilant with educating our patients on proper vision health and how to avoid damaging your eyes. As we spend more time staring at monitors, iPads, and smartphones, we increase the amount of blue light we’re exposed to, and that’s where blue light filtering glasses might help. In this blog by Invision Optical, we talk about blue light glasses and if they work or not.
What is blue light?
Blue light is hardly anything new, it just seems that way due to the ubiquity of blue-light-emitting electronics and recent trendiness of blue light glasses. Blue light waves, short, high-energy wavelengths on the visible light spectrum, occur naturally in sunlight and play a key role in helping you maintain a healthy circadian rhythm. It cues your body that it’s daytime, boosts your alertness and energy, and it improves your mood.
Is blue light bad for you?
There is some research that suggests that blue light may be responsible for retinal damage and increase the risk of age-related macular degeneration, which causes vision loss as people age. While blue light’s negative impact on eyesight may be disputed, we do know exposure to too much blue light, or exposure to blue light at unnatural times of day can definitely throw off your body’s natural sleep-wake cycle. That’s why many people have trouble falling asleep after using phones or watching TV right before bed: They’ve been taking in blue light, which tricks their bodies into thinking it’s daytime.
Do blue light glasses really work?
Blue light glasses are meant to work as blue light filters between your eyes and your digital screens (or LED and fluorescent lights). Tons of people swear by their blue light glasses, claiming midday headaches, fatigue, eye irritation, and insomnia are a thing of the past since treating themselves to a pair. While there is plenty of debate about the effectiveness of blue light glasses, there is also a lot of research that suggests that exposure to blue light, especially at night, can make falling asleep a real drag. Getting a pair for watching TV, Facebook stalking or working at night could be worth it.
