Blue-light blocking glasses
Another day at the office means another day of staring at your computer screen. You return home with tired eyes only to stare at your TV screen or mobile phone again. Whether we are working, studying or taking time off, most of our lives today revolve around looking at a screen. And no matter what digital activity you are partaking in, chances are you are being exposed to considerable amounts of blue light. In such cases, wearing blue light glasses or computer protection glasses would be recommended. Read on to know more about the benefits of blue light glasses!
What is blue light?
Before Thomas Edison’s groundbreaking invention, the sun was the only source of light we had. Candles, campfires, and lanterns all produce orange light. Fast forward to the present where our nights are brightly illuminated by our smartphones, tablets, mobile phones, and TVs. Aside from a few yellow light bulbs available in our homes, most of the lights we use consist of artificial blue light.
Blue light mimics sunlight at its brightest. Research shows that prolonged exposure to blue light affects our sleep cycle. Our body is attuned to an internal clock. Every morning, the sun’s natural blue light signals your body to wake up. And as darkness sets in, your body realises it is time to go to bed. However, with the varying amounts of blue light, we’re exposed to at night, your body’s clock gets confused. This results in exhaustion, tired and puffy eyes, and headaches. With time, exposure to artificial blue light can also cause several health concerns like a retinal injury. One way to combat the stress on your eyes is by using blue light blocking glasses. These glasses are also commonly referred to as glasses for computer usage or computer protection glasses.
How can they help?
Blue light blocking glasses are capable of blocking out 30% of blue light exposure. They can also help increase our production of melatonin which helps us fall asleep faster. The longer you wear these blue light blocking glasses, you can protect yourself against digital eye strain, which causes blurred vision and headaches.
If you still aren’t convinced about using blue light filters, here are a few additional benefits of blue light glasses:
Increased melatonin production
Melatonin is a hormone that helps control your body’s daily rhythm. When the sun sets, melatonin is released in your body, and these levels decrease when exposed to sunlight. Artificial blue light, however, interferes with the natural rise and fall of melatonin levels in our bodies. One of the benefits of using blue lights glasses is that you get to help your body maintain optimal melatonin levels. This helps you fall asleep faster at night and ensures you get an adequate amount of sleep.
Control cortisol release
Cortisol is another hormone just like melatonin and is involved in many bodily functions, mainly keeping blood sugar and blood pressure under control. It is also called the “stress hormone” as extra amounts of this hormone are released when you are stressed. Cortisol is released in the morning, and its levels fall throughout the day. Another of the many benefits of blue light glasses is that you can keep your cortisol levels in check as prolonged exposure to blue light can cause fluctuations.
Helpful for shift workers
Research shows that shift workers, particularly those in the night shift are found to be at high risk for circadian rhythm disruptions and fluctuating. This can increase their risk of a number of severe illnesses like heart disease, cancer, obesity, digestive problems, etc. Blue light filter glasses have several benefits. By using blue light blocking glasses, shift workers can regulate their internal body clocks and protect against fatal illnesses.
Prevent macular degeneration
Age-related macular degeneration or AMD is a problem that arises when a part of your retina (the macula) is damaged. A person with AMD will have a normal peripheral vision but loses their central vision. This means they cannot see fine details when looking at things that are close by or far away. While there are several causes of AMD, you are also likely to develop this condition if you are exposed to blue light for extended periods of time. Artificial blue light penetrates your eyes all the way to your retina. With blue light filter glasses, benefits can be reaped, and one of them is mitigating these problems.
