Core Concepts About Blue Light Blocking Glasses
Blue light blocking glasses have been proven to effectively address symptoms associated with eyestrain, including dry eye syndrome, blurred vision and headaches. They filter out blue light while simultaneously reducing LED screen glare glare glare as well as protecting retinas against UV radiation exposure.
Though these glasses may be popular, they don't do much to combat eye fatigue or improve sleep; however, they may help you remain more awake during the day.
They block blue light
Blue light is a high-frequency segment of visible light spectrum, which disrupts sleep-wake cycles and causes headaches. To reduce its harmful effects, blue light glasses with tinted lenses are designed to filter this out while also offering reduced brightness levels that relieve eye fatigue.
A good pair of blue light glasses should filter most blue light while still allowing some green light through, but before purchasing any, it's wise to test them first and choose those that filter between 400nm and 450nm (the range typically considered "blue") light.
Blue light may contribute to eye strain, but it isn't the sole factor responsible. Other contributing factors can include shifting focus, glare and contrast; and frequent blinking which also irritate the eyes. To reduce eye strain it's essential that screen time be limited before bed and block blue light glasses be worn - both can improve sleep quality as well as eye health.
They reduce eyestrain
Many who spend extensive periods of time using computers, tablets, or smartphones experience symptoms of digital eye strain such as blurred vision, dry eyes and headaches. The source may include factors like glare, prolonged screen time or suboptimal work setup - blue light blocking glasses may be suggested as a possible solution, though experts have cast doubt upon their effectiveness.

Studies have not demonstrated that blue light-filtering glasses or coatings on prescription lenses significantly alleviate eyestrain. This may be because most screens don't emit much blue light in the first place and glasses filtering only about 10%-25% of it.
Some experts have voiced concerns that blue light-blocking glasses might interfere with sleep and circadian rhythms, while preventing damage caused by constant exposure to bright blue light from digital screens and potentially helping slow or prevent age-related macular degeneration.
They improve sleep
Blue light blocking glasses help eliminate harmful wavelengths that disrupt sleep-wake cycles, eye strain, dry eye syndrome and headaches. They are available as standalone frames or add-ons to existing prescription eyewear; and blue light filters may even help reduce eye fatigue caused by computer and tablet screens due to glare.
Blue-light blocking glasses may help your sleep by stimulating the production of melatonin in your body, an essential hormone needed for maintaining a healthy circadian rhythm. But they should only be used alongside other components of good sleep hygiene such as healthy diet and physical activity to provide maximum effectiveness.
Ophthalmic glasses may help alleviate eye strain, but they won't necessarily improve sleep. According to a recent systematic review, blue-light filtering lenses don't prevent or treat insomnia - other strategies must be employed instead in order to maximize restful slumber such as turning off electronic devices an hour before bedtime.
They are safe for all-day use
Blue light can be found throughout the visible spectrum and is produced by smartphones, TVs, computer screens, office fluorescent lighting fixtures and natural sunlight. Although not as dangerous as UV radiation, blue light has the shortest wavelength and highest energy of all colors emitted by smartphones, televisions, computer screens, office fluorescent lighting fixtures and sunlight; its primary function is inhibiting production of melatonin which is essential to sleep cycles; too much blue light at night may cause eye strain.
Eye strain is often due to a combination of factors, including shifting focus, glare, lack of humidity and poor setup. To prevent eye strain from occurring take frequent breaks from your computer and ensure that the room is well lit; additionally consider wearing blue light filtering glasses throughout the day which reduce eye strain while providing comfortable working conditions; these glasses can even be worn alongside prescription eyeglasses!
