Why You Need to Be Serious About Blue Light Glasses
All digital devices and some office fluorescent lights emit blue light, the wavelength with the highest energy. This hue represents all visible light spectrum. Small amounts of natural blue light from the sun are good for our health; however, too much artificial blue light can disrupt sleep cycles and cause eye strain. Blue-light blocking glasses help avoid these side effects by filtering out this harmful illumination. Reduces Eye Strain Blue light blocking glasses contain lenses designed to filter out harmful wavelengths that contribute to eyestrain, helping you focus and improve posture while increasing comfort and eliminating uncomfortable symptoms. When purchasing one of these, make sure it has been created by an eye specialist or at least boasts scientific research or clinical trials in support of its product. Consider lens quality when purchasing blue light glasses. Poorly made lenses may actually cause more eye strain than they protect from; they may not block out all the light, and may display chromatic aberrations which shift certain hues around. When purchasing, look for lenses with an index number of 1.67 or higher; additionally, check for spectrophotometer reports showing exactly what percentage of blue light your glasses filter out to get a clearer idea of their efficacy. Helps You Fall Asleep Your workday may leave little time for relaxation, so instead, you unwind by scrolling social media until it's time for bed. Although blue light from screens may cause eyestrain, it also disrupts sleep. Glasses with special coatings or tints can help your eyes protect themselves from the high-energy blue wavelengths found on digital screens, filtering out light to expose darker parts of the spectrum that promote melatonin production, helping you sleep easier at night. Studies have suggested that blue light-blocking glasses may help with insomnia; however, research remains inconclusive due to studies being too small or not looking into whether specific blue light-blocking filters actually have an impact on sleeping patterns. If you have trouble sleeping however, wearing these glasses for several hours before bed can help increase melatonin levels and promote restful slumber. Boosts Your Mood Blue light glasses are non-prescription eyewear designed to filter or block blue light emitted by digital devices like computers and smartphones, providing relief from digital eye strain as well as sleep disturbances associated with overexposure to blue light at night, such as difficulty falling asleep and reduced deep restful rest. Studies have proven their efficacy at helping alleviate digital eye strain while also alleviating symptoms caused by overexposure to blue light such as difficulty falling asleep quickly or reduced depth sleep quality.

Blue light blocking glasses use tints or coatings that reflect or absorb specific frequencies of light to block them from reaching the retina, helping to protect sleep by keeping these frequencies from reaching it. Depending on their lens color, blue light glasses may block some, all, or none of these sleep-disruptive frequencies.
