Blue light glasses are non-prescription sunglasses equipped with tints or filtering material to block some of the blue light emitted by digital devices, in order to help prevent eye strain and macular degeneration. These glasses may even help improve eye health!
Studies have revealed that exposure to blue light before sleeping can disrupt your natural biological clock and diminish production of melatonin - the hormone associated with restful slumber. blue light blocking glasses can help improve your sleep at night and wake you feeling more rejuvenated than before.
Reduces Eye Strain
blue light blocking glasses were developed with the idea in mind that prolonged exposure to artificial sources of blue light - such as smartphones, tablets and laptops - can lead to eye strain. While this is indeed the case, discomfort from digital screens could also result from other causes including glare, poor posture or tired muscles.
Blue light-filtering glasses may make promises of improved vision from some retailers; however, according to high-quality research on this subject conducted by Cochrane database of high-quality research on this matter found they had minimal or no influence on visual acuity.
Long hours staring at digital screens can cause your blink rate to decrease, leading to eye strain and headaches. To reduce this effect, take regular breaks from working and try not slouching when working; getting some fresh air, stretching neck and shoulders regularly or doing backward shoulder rolls periodically may also be beneficial.
Prevents Insomnia
Blue light from screens suppresses melatonin production at night, keeping you awake. These glasses were created to filter out that blue light before it can reach the retina - helping you sleep easier!
Studies showed that participants with insomnia experienced significant improvements in sleep when wearing blue-light filters. Furthermore, these filters helped prevent eye strain caused by staring at one object for too long.
Blue light glasses alone won't solve poor sleep; to improve it, limit screen time, use dimmable lighting, take breaks when using devices, follow the 20-20-20 rule (which involves looking away for 20 seconds every 20 minutes from devices for 20 seconds or so) or establish a good sleeping regimen that guarantees adequate restful zzzs each night so you feel refreshed when morning comes around.
Reduces Risk of Eye Diseases
Studies on blue light from electronic screens may contribute to long-term vision damage such as macular degeneration; however, most studies were performed on animals or in lab settings. Block blue light glasses may help reduce this risk by blocking or reflecting harmful wavelengths back onto themselves and away from your eyes.
These glasses typically feature tinted lenses or coatings that alter the hue of light coming in, creating yellower, less bright illumination that reduces eye strain and fatigue. Furthermore, anti-reflective coatings make the lenses clearer and more comfortable to wear for extended periods of time.
Though glasses may help, other steps should also be taken to alleviate eye strain. These steps include limiting screen time and using your device's dark mode at night to stimulate melatonin production for regular sleep cycles and promote regular melatonin production. Furthermore, taking frequent breaks away from screens by practicing the 20-20-20 rule -- looking at something 20 feet away for 20 seconds every 20 minutes -- can reduce eyestrain significantly.
Increases Focus
Studies conducted recently demonstrated that students wearing blue light blocking glasses were better able to focus and retain information than those wearing regular glasses, suggesting that eye strain does not necessarily correlate with lack of focus and retention; rather, factors like shifting focus, glare, contrast or infrequent blinking could more likely contribute to symptoms associated with poor attention and retention.
Breaks and limiting screen time at night will help combat eye fatigue, while practicing good posture can reduce back, neck and shoulder discomfort caused by sitting too closely to a computer screen.
Blue light glasses may help combat some of the negative consequences associated with increased screen time, but they won't solve other issues. Users must be mindful of total screen time spent and practice healthy behaviors such as regular exercise, sleep and eating well in addition to looking into alternative sources of blue light such as sunlight or fluorescent lights as potential solutions.
