Blue light blocking glasses filter out high energy visible (HEV) light that comes from smartphones, televisions, computer screens and office lighting sources such as smartphones. HEV light has the shortest wavelengths and highest levels of energy content.

Studies relating to blue light filters remain inconclusive; however, they may provide subjective relief from eyestrain and glare while using digital screen devices.

They Block Blue Light

Blue light glasses can help reduce eye strain, dry eyes, and headaches caused by digital screen devices, including TV, phone, tablet and computer screens. Blue light filters also provide relief from eye strain, dry eyes and headaches while aiding people living with migraines who can benefit from lower glare and light levels of lenses like these.

These glasses feature amber tinted lenses designed to reflect and absorb blue light emitted from screens, such as mobile devices. While you could purchase prescription blue-blocking glasses from a physical store, their effectiveness may not compare to purchasing an amber lens tinted specifically according to your screen usage needs by an expert.

Blue-light blocking glasses can be beneficial to anyone who spends long periods staring at digital screens, such as office workers, students and those needing devices late at night for either work or social purposes.

They Help You Sleep Better

Though experts don’t yet fully understand why blue light blocking glasses help improve our sleep, they do recognize that when your eyes aren’t in optimal condition to see at night it can make falling asleep difficult and staying asleep all the way through the night. Be it due to glare or simply too much time spent staring at screens these issues may interfere with getting quality restful rest.

As long as you wear blue light-blocking glasses about an hour before bedtime and follow other healthy sleep practices (like exercising early morning and drinking tart cherry juice) then your body can experience optimal melatonin levels and be ready for restful night’s rest.

Unfortunately, it can be challenging to obtain accurate information on how well blue light-blocking glasses actually work due to limited research on them. A 2020 systematic review and meta-analysis concluded that such glasses may help some individuals suffering from sleeping disorders and delayed sleep phase syndrome.

They Help You Reduce Eye Strain

Blue light blocking glasses help make life easier on your eyes by filtering out blue light emitted by digital screens, thereby alleviating eye fatigue, dry eye symptoms and headaches. They’re particularly helpful for people with high light sensitivity or migraines.

Digital eye strain is often blamed on blue light exposure alone; however, other contributing factors include glare, low humidity, excessive screen viewing time and poor screen setup as well as poor posture.

Studies have varied greatly in their findings on whether blue light-blocking glasses help reduce digital eye strain; some studies even demonstrated no benefit, with experts even questioning if such glasses are necessary at all. To prevent eyestrain and reduce digital eye strain, follow the 20-20-20 rule: every 20 minutes look away for 20 seconds from your screen for about 20 seconds to give your eyes a break and reduce screen glare by adding an antireflective coating to prescription lenses.

They Help You Look Younger

Blue light from electronic screens such as smartphones, computer monitors, TVs and fluorescent lights interferes with our natural sleep cycle and may trigger headaches, dry eyes and eye strain. By blocking this light through blue light glasses you may get better restful nights of rest while looking healthier overall.

Block blue light glasses are often sold with the claim that they will help alleviate problems associated with digital devices, like eyestrain and headaches, but so far the evidence is inconclusive. A recent Cochrane review — known for providing comprehensive summaries of scientific research — concluded that blue-light glasses don’t significantly alleviate symptoms like eyestrain.

While glasses may help, they might not be essential. Glare reduction makes focusing easier, and can also help avoid screen burn – both problems associated with long hours spent staring at screens. You could still achieve similar results by simply decreasing screen time or maintaining consistent room lighting conditions.
