desertcart.com: Spectra479 - Fit Over 99.9% Blue Light Blocking Glasses for Sleep - Amber Nighttime Eyewear - Turn your Prescription & Reading Glasses Into World-Class Blue Blockers : Health & Household

Review: Great starter glasses - Great price to see if these fit into your health routine. Quality seems good and should last a while. Comfortable and fit over both of my glasses. The first night I used them I had 3 hours of REM sleep (double what I have normally). That has never happened in the 3+ years I've been tracking my sleep.
Review: Great Blue Blockers for over glass, beware of glass height - Review of Spectra479 Blue Blocking Fit-Over Glasses I’ve been using the Spectra479 blue blocking fit-over glasses and have been very impressed with their performance. The blocking effect is immediately noticeable—they truly cut down on blue light in a big way, making a huge difference in eye strain and sleep quality. If you're sensitive to blue light, these are a game-changer. The glasses are well made, sturdy, and feel like a quality product. I appreciate that they’re designed to fit over prescription glasses, but it’s worth noting that they don’t fit over every pair. I have two pairs of Rx glasses—these fit comfortably over one pair, but not over the other, which has a more oval shape. If your glasses are taller than approximately 42m (about 1.65 inches), you might have trouble getting a good fit. Overall, I’d definitely recommend them for anyone looking to reduce blue light exposure—just be sure to check the size of your frames first.

## Features

- FIT OVER - Theses glasses fit over top of prescription and reading glasses. They can also be worn on their own.
- SUPERIOR BLUE LIGHT BLOCKING - The best selling Spectra479 amber lenses can now turn your prescription and reading glasses into anti blue light glasses for computer and nighttime tv use.
- BRIGHT & CLEAR LENSES - These are designed to pass as much non-blue light through as possible. There is no dark tint and they are not polarized. You can still make eye contact with loved ones and even forget you are wearing them. Key Product Features
- TECHNICAL SPECS - Tested to block 99.9+% of light from 280 - 510nm (this includes UV). The wavelengths between 450 - 510nm are the most disruptive wavelength of light at night. It is also the same frequency of light that is blasted directly into your eyeballs from electronic devices! Always wear protection!

### ⭐⭐⭐⭐ Comfortable
*by C***Y on March 4, 2026*

Despite suffering from advanced glaucoma and optic nerve damage due to a medical mistake, I find reasons to stay positive. I wear these incredibly comfortable glasses over my usual ones at night while watching TV, and they’ve become a game-changer—completely issue-free and worth every moment.
