Blue light blocking glasses block out high-energy blue wavelengths emitted from digital screens, helping reduce digital eye strain symptoms such as red eyes, dry eye syndrome and glare.
However, research published in 2021 suggests that these glasses may not really help to alleviate eye strain. A study of 120 computer users suffering from eye strain tested the efficacy of blue blockers versus clear glasses over two hours of screen work.
Blocking Blue Light
Blue light filter glasses are one effective way of blocking blue light, helping reduce digital eye strain. Typically featuring tints which reflect or absorb blue light as well as anti-reflective coatings to decrease glare, these lenses can also be worn over prescription or non-prescription lenses for maximum benefit.
Blue light from screens and LED lights can interfere with our body's natural sleep cycle, leading to fatigue, headaches and other symptoms. Therefore, it is essential that users become mindful of how long they spend using devices before trying to reduce screen time usage.
Though the American Academy of Ophthalmology hasn't found evidence that computer use damages your eyes, many individuals report wearing block blue light glasses to help them sleep easier at night and experience less eye strain while using electronic devices during evening use. This may be related to their impact on circadian rhythm or simply by reducing harsh stimuli before bed.
Blocking Glare
Blue light, the short wavelength end of the visible spectrum that comes from both natural sunlight and artificially generated LED lighting and digital screen devices like computers, tablets and phones, is produced both naturally by sunbeams as well as artificially by LEDs and digital display devices like computers, tablets and phones. Although blue light may help promote alertness it also suppresses our natural melatonin production at night and keeps us awake through its stimulation of your central nervous system.
To prevent computer eye strain, the best way is to limit screen time in the hours leading up to bed, and take frequent breaks while working at a computer or using other electronic devices. Furthermore, use anti-reflective lenses on glasses in order to limit reflections from surfaces such as monitors and surfaces from reflecting back onto their surfaces and creating glare on your glasses' surfaces.
Although blue light blocking glasses can reduce symptoms associated with computer eye strain such as fatigue, dry eyes, headaches and neck-shoulder pain, they won't protect your retinas against long-term damage - for that you need UV protective lenses.
Blocking UV Light
Blue light can be found all around us; from sunlight and digital screens. This shortwave, high-energy form of illumination has the power to disrupt sleep schedules.
Blue light blocking glasses are a great way to reduce eye strain and fatigue while helping protect retinal damage over time.
Most blue light blocking glasses feature polarized lenses to further reduce glare and make viewing your screen easier, and may feature anti-reflective coating for added comfort.
Some blue light-blocking glasses feature tinting to add contrast and increase colors' vibrancy, which is especially helpful for those working all day with digital devices as it reduces eye strain and fatigue. It should be noted that not all tinted glasses provide equal levels of blue light filtration - some provide extensive blue light filtering while others only provide moderate levels.
Comfort
Blue light-blocking glasses are lightweight and designed to fit snugly around your ears and nose without pinching the bridge of your nose or sliding off of your forehead, providing comfort as you work or watch movies and TV without discomfort.
Popular blue light filters resemble regular reading glasses with clear lenses and can be fitted to your prescription. Some types include tinted or yellow/amber lenses to filter out more harmful blue light rays to help reduce digital eye strain. Consider looking for pairs that also provide UV protection and offer wide field of vision so you can view your computer screen clearly.
Blue light from your screens interferes with your body's natural sleep and wake cycle and prevents your eyes from producing the sleep-inducing hormone melatonin. While studies vary on their results, some have discovered that using blue light filters may help improve both sleep quality and overall health if used for extended periods before bedtime.
