These glasses filter out the harmful blue light. Anti-blue light lenses are a must for people who spend time with computers, phones, tablets, and other electronic equipment during the evening.
We are in the era of electronics. During the evening, you are probably watching something on Netflix, YouTube, TV, catching up on work on a computer or a tablet, or just surfing the web. These artificial lights from gadgets emit a blue glow, a light wavelength similar to the day time sky. This blue light enters your eyes and signals your brain to think it is still day time. Your mind then restricts the flow of melatonin through your body.
While many are aware of how blue light from electronics disrupts sleep, many do not know that about 25% of the blue light from fluorescent lighting and 35% from LED lights is also damaging to eye health, over time, raising the risk of vision problems including macular degeneration. The degeneration is pretty subtle and minimal, but why take any chances?
The glasses are for adult people with normal vision. Email us if you need a different strength.
