When you spend all day looking at digital screens, eye strain and headaches are common side effects. These symptoms are often caused by harmful blue light emitted from screens. Some people use blue light-blocking glasses to help alleviate these symptoms. However, research has shown that these glasses are less effective than other simple solutions, such as taking breaks from screens and adjusting screen settings.
Reduce Eye Strain
Eye strain is a common problem caused by several factors, including spending too much time looking at digital screens. Blue light is a type of visible light emitted from digital screens, and it can have several negative effects on the eyes, including eye strain, headaches, and dry eyes. The best blue light blocking glasses are eyewear that can help reduce eye strain by blocking or filtering blue light from entering the eyes. These glasses are typically designed to block 20-40% of blue light and can be worn using any digital screen. Other items contributing to eye strain include the bright lights in a room and not blinking enough, leading to dry eyes. To help prevent eye strain, try to sit farther away from your screen. Use artificial tears to avoid dry eye, and make sure you’re blinking enough. It’s also a good idea to avoid too much glare and try to minimize distractions so that you can focus on what you’re doing.
Reduce Dry Eye
As much as we rely on screens to do our jobs, catch up on the news and entertainment, connect with friends and family, and even order food, they can cause serious eye strain and headaches. Thankfully, you can make several simple changes to prevent screen discomfort. Blue light-blocking glasses are a good start, but you also want to consider using a humidifier to reduce dry eye and reduce your screen time at night. A recent study comparing blue light filtering glasses to regular clear lenses found that the lenses didn’t significantly improve eye strain symptoms. They did, however, help with sleep disturbances. This is because the blue light from digital screens interferes with the release of melatonin, a hormone that regulates your natural circadian rhythm and helps you fall asleep at night. Blue light filters on computer or phone screens aren’t just for comfort; they may be important for preventing long-term retinal damage. This is because it’s been shown that the blue light emitted by digital devices may suppress the production of retinoprotective opsins, which are proteins in your retina that protect against damaging sunlight. If you’re interested in trying blue light blockers, look for a pair that also offers UV protection, which is a must if you’ll be wearing them outside or by the pool. Be sure to choose a brand that advertises blue light blocking and not just a lens coating.
Get a Better Night’s Sleep
Blue light is known to sabotage our sleep schedule by interfering with our circadian rhythm. If you use a device late at night and struggle to fall asleep, wearing blue light-blocking glasses could help. Blue light-blocking glasses can promote a more restful sleep by preventing screentime from affecting your natural sleep cycle and hindering the release of melatonin. However, you’ll want to research the blue light filter glasses you purchase to ensure they are legitimate. You can read the return policy and customer reviews before buying. You can also ask your optometrist for recommendations based on your lifestyle and preferences. Although avoiding screens in the evening can help you get a better night’s, It’s not just your screen’s brightness and color that affects you, but how often you look at it and for how long.
Reduce Stress
If your work-from-home schedule involves spending several hours a day in front of a screen, you may be experiencing discomfort in the form of eye strain and headaches. While it can be difficult to disconnect from your screen, you can minimize blue light exposure by wearing blue light-blocking glasses, taking regular breaks, reducing your screen time before bed, and ensuring your screens are positioned properly to minimize glare. Blue light blockers have become so popular because they filter out the specific wavelength of light associated with digital eye strain, reducing dry eye and blurred vision. However, this wavelength can also interfere with natural circadian rhythms and disrupt sleep-inducing melatonin. A study funded by a company that sells blue light glasses found that the lenses agitated computer users more than those who wore clear glasses. Blue light can affect our body’s circadian rhythms, and this disruption is a significant contributor to stress and insomnia. It’s important to note that the symptoms of digital eye strain aren’t caused by blue light itself but rather the tension that develops in our eyes and necks as we spend long periods looking at screens. Whether you’re trying to alleviate your headaches or migraines caused by screentime, try using a pair of prescription glasses designed to block the blue, red, and amber light wavelengths that trigger migraines and other light-sensitive conditions without introducing disruptive distortions in color perception.
