![]() When possible, limit your screen time, especially after sunset. If you feel screens are impacting your sleep, you can use blue-light-blocking lightbulbs, especially in the rooms where you spend the most time at night. No matter how far away or near you let your gaze go, the main goal is to look away from the screen and let your eyes take in other objects and distances to reduce strain and fatigue. After about 20 minutes of looking at a screen, look at something at least 20 feet away for 20 seconds. Many eye doctors also suggest practicing the 20-20-20 rule. You can use the night or dark mode feature built into your device. Some eyewear can include blue light or glare reduction in the lenses for prolonged screen time. You can wear prescription and nonprescription eyeglasses when you’re using electronics. Privacy and anti-glare filters are also available.Īdditional ways to limit blue light exposure Some filters will also include coatings that protect your screen from impacts, scratches, and smudges. Most brands offer filters to fit specific models. Make sure the dimensions of the screen filter are the correct size for your device. To prevent distortion and discoloration, select a screen protector that retains the display’s original color and brightness. Choose brands that are designed or recommended by healthcare professionals. Look for companies that use third-party testing and certification. Check out the company’s website to get a feel for the brand. Read online customer reviews and ratings from Trustpilot or the Better Business Bureau (BBB). Look for a reputable company that backs product quality with a generous warranty or return policy. What to look for when purchasing a blue light screen protectorīefore you buy a blue light screen protector, consider the following: Further research is required to understand the potential health benefits of using a screen protector to reduce blue light exposure. “Optical radiation” is a term for the range of visible light, light that the human eye doesn’t see (such as ultraviolet, UV, and infrared), as well things like microwaves and X-rays.Īccording to a 2017 review of studies, there is a lack of high quality research on blue-light-filtering devices and lenses and, as a result, there is no high quality evidence that supports the effectiveness of blue-light-blocking eyewear in reducing eye fatigue, enhancing sleep quality, or boosting visual performance.Ī 2020 study using Apple devices found that reducing the brightness and enabling night shift mode was more effective than a screen protector in reducing blue light intensity. Furthermore, the radiation emitted from the devices was lower than international exposure limits and natural sunlight exposure. Research from 2016 suggests that lamps and electronic devices do not emit enough optical radiation to cause ocular damage, even during long periods of viewing. The scientific research surrounding the purported risks of blue light exposure and benefits of blue light reduction provides mixed results. People say blue-light-blocking products, including eyewear and screen protectors, reduce symptoms of blue light exposure such as eye irritation, headaches, and fatigue. Plenty of anecdotal reports claim that filtering blue light from screens provides benefits.
