Blue light, the wavelengths with the highest energy levels within the visible light spectrum, emitted by digital screens can disrupt our natural sleep/wake cycle and cause eye strain, headaches and neck/shoulder pain.
Blue light glasses filter out high-energy visible (HEV) blue light, decreasing exposure from digital screens and helping alleviate symptoms of eye strain and fatigue.
What is Blue Light?
Blue light has the shortest wavelength and highest energy in the visible spectrum, and is emitted by electronic devices such as smartphones, tablets, televisions, as well as LED and fluorescent lamps.
Experts have expressed concerns that blue light from digital screens may disrupt sleep patterns, contribute to eye strain and cause macular degeneration. While research remains inconclusive, some individuals have reported wearing glasses fitted with blue light filters helps alleviate symptoms associated with screen use such as glare and other symptoms like headaches.
Some glasses feature amber tints to reduce harmful blue light emissions from screens. You may also purchase lenses designed specifically to block blue light based on your prescription - however this must be assessed by an eye care provider based on your needs and screen usage. Optimally suited glasses will feature a transmittance spectrum report showing exactly how much blue light they block; aim for ones that filter out wavelengths greater than 455nm for optimal performance.
How Do Blue Light Blocking Glasses Work?
Blue light blocking glasses filter high-energy visible (HEV) light emitted by digital screens, providing a more comfortable working experience while mitigating potential effects of prolonged screen use on eyes and sleep cycles.
Blue light lenses typically include anti-reflective coatings to minimize the amount of distracting blue and other distracting light that reflects off of eyeglasses and into your eye, thus limiting visibility of blue light entering. Many blue light lenses even feature amber tinting to further decrease visible blue light while still allowing clear vision.
Studies have suggested that blue light-blocking glasses may help improve sleep quality by decreasing melatonin suppression caused by exposure to digital devices at night, yet this remains unproven and other research indicates they don't prevent eye strain or other symptoms associated with digital screen use - thus the ideal blue light glasses would have built-in blue light protection as opposed to just being an add-on coating on an ordinary prescription frame.
Can I Wear Blue Light Glasses All The Time?
Blue light glasses may provide many people with relief, but they should not be considered an instant cure-all for digital eye strain symptoms. Instead, consider making adjustments to your work environment in order to alleviate digital eye strain symptoms, such as matching ambient lighting to screen brightness or taking regular breaks from screen time.
Make sure that the quality of your blue light lenses is high-grade rather than cheaply made as cheaply-made lenses can distort vision and lead to further eye strain. Look for lenses that are clear during the daytime but red-tinted in the evening for maximum protection against harmful blue light rays.
If you suffer from hyper light sensitivity or migraines, blue light filters may not provide sufficient protection for your eyes and health. A pair of blue light glasses may offer sufficient protection and aid better sleep for those without such conditions.
What Are the Benefits of Blue Light Blocking Glasses?
Blue light blocking glasses offer several distinct benefits that can help improve sleep at night. Wearing them for just a few hours before bedtime to reduce exposure to blue light helps regulate circadian rhythm and promote greater melatonin production for restful slumber.
Block blue light glasses also offer another important benefit of screen time: protecting the eyes from eye strain, dryness, blurriness of vision, headaches, neck-and-shoulder pain. They're especially beneficial for students working on computers or children using digital devices often.
Many of our blue-light-blocking frames are available both as prescription and nonprescription versions to meet your unique needs. When searching for suitable glasses to block blue light, find ones with comfortable frames that won't feel cumbersome throughout the day - this way they won't affect your vision too much!
