Fit Over Blue Light Blocking Glasses for Sleep - Amber Nighttime Eyewear

These glasses are designed to fit over your prescription and reading glasses. They can also be worn independently. The best-selling Spectra479 amber lenses can now turn your regular glasses into anti-blue light glasses for computer and nighttime TV use. The lenses are designed to allow as much non-blue light through as possible, with no dark tint and no polarization, so you can still make eye contact with loved ones and forget you're wearing them.

The glasses have been tested to block 100% of light from 280-490nm, including UV. They block 99.9+% of light in the critical 450-510nm range, which is the most disruptive wavelength of light at night and the same frequency emitted by electronic devices. This blue light exposure after dark has been proven to disrupt the body's natural melatonin production and circadian rhythm.

The 450-510nm range is by far the most disruptive to the body, and clear or yellow-tinted lenses are unable to effectively block these longer blue and cyan wavelengths. Wearing these glasses allows you to safely use computers, tablets, and phones after dark, protecting your body's natural nighttime physiology and enabling rapid sleep onset and deep, natural sleep cycles.

There's no need to buy expensive custom-made blue blockers - these lightweight glasses fit instantly over your existing prescription or reading glasses, transforming them into world-class blue light blockers. They also work great as standalone glasses, allowing you to use them only when needed, such as with your reading glasses for tablet use, without the hassle of clip-on styles.

Simply slip these glasses on over your regular glasses - no clips to deal with. This makes them very convenient if you use multiple pairs of glasses or only need the blue light protection part-time. By using these glasses when using screens before bed, you can prevent blue light from disrupting your sleep.

In addition to shielding your melatonin production, these glasses provide instant relief for eye strain and fatigue, which are common side effects of exposure to short-wave blue light. Block that blue light and give your eyes a break!
