You may have heard that blue light glasses can help reduce headaches. Read on to learn more about the benefits of this eyewear. They include reducing eyestrain, poor sleep, and digital eye strain. These glasses are essential for people who spend a lot of time in the sun. You may also need to wear them if you work in an office with computers and electronic devices.
If you’ve ever experienced a headache from working at a desk, you know how bad it can be. The invention of the best blue light-blocking products was heralded to solve these problems. But unfortunately, studies have not proven that they reduce headaches and eye strain. It may be worth a try, though.
While blue-light-blocking glasses are a significant first step, there are many other things you can do to improve your sleep and reduce the frequency of your headaches. For example, try to take mini-breaks, which involve looking at something across the room for 20 seconds. You may also want to limit your screen time closer to bedtime. This is because blue light exposure disrupts the production of melatonin, a hormone responsible for regulating sleep.
The most common question about whether blue-light glasses reduce eyestrain is, “can they work?” The answer is complicated. Although some studies show blue-light glasses can reduce eye strain, others claim they do not. A small 2017 study found that people who wore blue-light glasses experienced less eye strain and reported longer sleep. While this is encouraging news, further research is needed to prove whether blue-light glasses can reduce eye strain. The symptoms of digital eye strain may be attributed to long periods of exposure to digital screens. People who spend more than two hours in front of a computer screen are at high risk for digital eye strain.
One way to reduce eye strain from digital screens is to take frequent breaks. For example, you should aim to look at objects twenty feet away for 20 seconds every 20 minutes to help prevent eye strain. Another effective method is to sit 25 inches away from a computer screen and tilt it down to minimize glare. Also, it is recommended to dim computer monitors because staring at a screen for too long without blinking can lead to eye strain.
Dry eye is another common problem resulting from digital eye strain. Women and older people are more prone to it. In addition, certain autoimmune diseases and thyroid conditions may increase the risk of dry eye. In most cases, these symptoms go away once you stop using the computer or device for an extended period. However, digital eye strain can lead to chronic symptoms for some people. It can cause headaches, which are often painful and can lead to migraines in some cases.
Reduces poor sleep
Wearing blue-light glasses can improve your sleep quality and decrease computer screen time. They strengthen your circadian rhythm, which regulates your sleep-wake cycle. People who are night owls are more likely to experience the benefits of blue-light glasses, whereas morning larks benefit less from them. Lack of sleep can affect your decision-making processes and behaviors at work and in relationships. To help you get the sleep you need, try these glasses.
In a recent study, researchers from the University of Colorado, Boulder, and the University of Oregon conducted a study in which first-year undergraduate students with sleep complaints were randomly assigned to wear amber-tinted lenses or blue-light-blocking glasses. The lenses were worn before bed for two weeks, followed by a baseline period and a control condition. Then, in a randomized crossover design, the lenses were compared to no lenses and the pre-treatment baseline. Finally, the lenses were worn for four nights in each condition.
