What Are Blue Light Reading Glasses? — ReadingGlasses.CO/
Blue light reading glasses are a type of eyewear designed to filter out the blue-violet light emitted by digital screens. Blue light is high-energy visible (HEV) light that can cause eye strain, headaches, and sleep disturbances. Blue light reading glasses can help reduce these symptoms by filtering-out blue light. They are available in prescription and non-prescription options and can be worn by anyone who spends a lot of time in front of digital screens.
UnitedHealthcare, people now spend an average of 13 hours per day on screens since the emergence of COVID-19. The Vision Council reports about 80% of American adults use digital devices for more than two hours a day. While no amount of blue light exposure is considered "good," it's difficult to say how much is too much since everyone responds differently to screen exposure and blue-violet light.
Blue light has more energy than other colors of light and can damage the cells in the retina. It can also affect the circadian rhythm and the production of melatonin, which are important for sleep and health. Blue light exposure may increase the risk of macular degeneration, a disease of the retina, and other diseases like diabetes, heart disease, obesity, depression, and some cancers. Blue light is more prevalent in artificial and digital light sources than is natural light.
Blue light reading glasses are glasses with lenses designed to reduce and specifically filter the amount of blue-violet light that reaches the eye. These lenses filter blue-violet light rays to help prevent them from entering your eye and causing potential damage. Blue light can cause headaches and blurred vision, it can damage the cells in the retina. When blue light damages the cells in the retina, it may increase the risk of macular degeneration, a disease of the retina.
Macular degeneration is more prevalent in people over the age of 50, but it can occur earlier in life. Exposure to blue-violet light is thought to increase the chances of early-onset macular degeneration. It can also affect circadian rhythms and the production of melatonin, each important for sleep and optimal health. Additionally, blue light may contribute to premature skin aging.
The percentage of blue light filtered from a pair of blue light-filtering glasses varies from lens-to-lens. Clear lenses with a blue light coating can filter between 5% and 40% of the blue light spectrum that can affect your eyes. If you want to filter more blue light, the lenses of your glasses will likely require a yellow or amber tint, which most people feel is unflattering to the face.
Blue light reading glasses filter out up to 30% of harmful blue-violet light emitted from digital screens such as smartphones, tablets, laptops, and more. They are available as prescription lenses over-the-counter (OTC) reading glasses or glasses that are only used for the purpose of blocking blue light (with no Rx or magnification).
