Blue light glasses may help mitigate symptoms associated with digital screen usage such as eye strain, dry eyes and insomnia. Furthermore, these glasses can improve sleep quality by mitigating the harmful effects of blue light exposure on melatonin production and circadian rhythms.
Blocking Blue Light
Blue light from digital devices such as smartphones, tablets and computers can disrupt our natural sleep-wake cycle and reduce our ability to produce melatonin. Wearing glasses that filter out this type of blue light may help reduce eye strain and headaches for those spending long hours looking at screens – an excellent investment for anyone spending hours staring into them each day!
Blue light blocking glasses have often been controversial, yet many believe they can reduce eye fatigue and improve vision overall. If you want to give them a try yourself, start by finding a pair that fits well and complements your personal style, make sure it has a flexible return policy, and read reviews from previous buyers before purchasing one.
Though wearing blue light glasses may help, developing better screen habits during your daily activities may have even greater positive results on your eyes. Use electronic devices at least 20 feet from your face, taking frequent breaks to refocus them as necessary.
Reducing Eye Strain
Staring at electronics for extended periods can cause eye strain, making reading or watching video uncomfortable and painful. Blue light glasses are designed to filter out this artificial blue light, limiting how much of it enters your eyes according to sellers.
However, opinions differ regarding whether these glasses actually help relieve eye strain. While some research indicates that filters do block some blue light to aid with CVS symptoms, other studies have demonstrated otherwise.
Researchers conducted a trial with 120 eye strain-symptomatic participants. Clear lenses or those equipped with blue light blocking technology were offered; researchers discovered that neither significantly reduced symptoms compared to clear lenses. It should also be noted that other factors can contribute to eye strain such as glare and uncorrected astigmatism – for this reason it’s always wise to consult an optometrist first if any concerns arise.
Reducing Eye Fatigue
Modern life exposes us to excessive amounts of blue light, which can contribute to eye strain, headaches, dry eyes and insomnia. Wearing glasses that filter out blue light may help alleviate discomfort when combined with other optometrist-recommended practices such as blinking frequently or using artificial tears for proper eye moisturization.
Blue light-filtering glasses are typically designed to block a percentage of blue light and typically come with tinted yellow lenses; some even feature clear lenses. Furthermore, they may feature anti-reflective coatings that reduce screen glare as well, Maturi notes.
Research hasn’t demonstrated that blue light-blocking glasses significantly reduce eye strain or improve sleep; Maturi advises focusing on decreasing screen time and practicing good screen habits instead to alleviate symptoms, like the 20-20-20 rule whereby looking 20 feet away every 20 minutes to help focus your eyes and increase blink rate.
Boosting Sleep
Media reports have promoted blue light filter glasses as an aid to improved sleep, yet this claim has yet to be supported by research. One theory suggests that blue light sabotages our circadian rhythm, telling our bodies when it’s time to wake up or sleep; those who experience later sleep periods could benefit more; however results from previous small studies and limited populations remain limited.
No matter the perceived or actual benefits they may or may not provide, blue light blocking glasses are an effective solution for those seeking to reduce screen use at night. Aside from relieving eye strain and potentially helping dry eyes, blue light glasses can also help improve sleep by not disrupting circadian rhythm and suppressing melatonin production at night. If long-term retina damage concerns arise when using screens for prolonged periods (i.e. using them every two hours instead), follow the 20-20-20 rule every two hours when viewing digital media at night when using screens at night if using screens before bedtime – they’re only useful when using screens at night
