Blocking blue light is vitally important for anyone who spends significant amounts of time using digital devices, as it stimulates melatonin production and enhances circadian rhythm.
Opt for glasses that provide a lens transmittance spectrum report if you want to ensure they filter out blue light effectively. One way of testing this is to shine a flashlight onto the other side of the glasses – any black squares should appear if they work effectively.
Reduces Digital Eye Strain
Blue light from electronic screens and artificial lights can strain the eyes, leading to discomfort. Wearing block blue light glasses reduces this discomfort and allows you to continue using screen devices for extended periods.
Though all colors of light come from sources like the sun or digital devices, blue light tends to produce the greatest eye discomfort due to its short wavelength and higher energy output.
Studies have demonstrated that blue light-blocking glasses can alleviate some symptoms associated with digital eye strain, including dry eyes and headaches. Furthermore, such glasses can help you sleep more soundly by blocking blue light that disrupts melatonin production and delays its onset – all qualities essential for successful sleeping habits.
When looking for glasses that effectively block blue light, be sure they filter at least 50% of 450 nanometer light wavelength. Your eye care professional may suggest a pair that meets this criteria.
Helps You Sleep Better
Blue light suppresses melatonin production, the hormone responsible for our natural sleep/wake cycles. By wearing orange lenses that block blue light during the day, you can stimulate its production so your body is ready for restful slumber when its time.
Wearing glasses that filter out blue light in the evening can also help you fall asleep faster as your brain can more efficiently produce natural sleep-inducing chemicals. One study discovered that those wearing orange lenses in their evening eyewear fell asleep faster than those without them.
However, depending on blue-light-blocking lenses alone to meet your sleep needs isn’t wise. For optimal restful slumber, good sleep hygiene – including avoiding screens in the hours leading up to bedtime – must also be implemented. With that in mind, RISE app offers helpful reminders to wear your glasses when it’s time for bed by including “Block All Blue Light” habit on Energy Screen.
Helps Prevent Age-Related Macular Degeneration
Though blue light from natural sources such as sunlight is beneficial, and can help regulate our sleep-wake cycle, digital screens emitting blue light may interfere with this process and disrupt it, potentially leading to eye strain, insomnia or macular degeneration over time. By wearing blue-light blocking glasses at night you can help minimize its negative effects on both your eyes and overall health.
Blue light-blocking glasses use special lenses that filter out harmful wavelengths of blue light emitted by screens and devices, helping reduce eye fatigue, improve focus, and thwart vision issues like cataracts and age-related macular degeneration.
Research remains inconclusive and does not provide clear evidence of the benefits of blue-light filters on eyestrain, sleep or macular degeneration. To get maximum benefit out of blue-light glasses, optometrists suggest limiting screen exposure an hour or two before bed and taking regular breaks from devices in order to rest and refocus. In order to make the most out of them, select glasses that provide UV protection.
Helps Protect Your Eyes
Blue light glasses filter out harmful wavelengths emitted by digital screens to protect your eyesight and provide relief for people who are light sensitive, like migraine sufferers, by decreasing headaches and dry eyes as a result of light sensitivities caused by digital devices. A pair that also offers UV protection would be especially useful.
Blue light doesn’t directly damage your eyes, but too much blue light exposure can disrupt your circadian rhythm and hinder production of melatonin at night, leading to eye strain and disrupted sleep patterns. To minimize eye strain and promote healthy restful slumber, limit screen usage including smartphones, TVs, tablets and computers before bedtime.
If you must use electronic devices before bed, try following the 20-20-20 rule, which suggests looking at objects 20 feet away every 20 minutes for 20 seconds, to give your eyes a break and improve eye health. However, studies have not demonstrated that blue light filters on glasses significantly improve eye health or aid faster sleep at night.
