Review: Do a great job of blocking most blue and all UV - After lens replacement I was worried about UV and blue light since both are reported in the literature to be a problem that may cause macular degeneration, which is particularly a risk after lens replacement according to what I've been told. Anyway, these fit well over glasses and the color is not very obnoxious. It took a day or so to get used to. It's kind of like putting your "night-time" phone or computer setting on the whole world. :) I can see the blue-blocking (though I don't have any trouble distinguishing shades of blue wearing them, it's only partial blocking) and I tested the UV blocking with a UV lamp and fluorescent paper, they seemed to work for that too. Happy to find them.
Review: They Have Helped! - I have been looking for a pair of fit-over glasses to use during work hours on the computer. I work on the computer for my job eight hours a day. I also use them at home when watching the TV and looking at my phone. Before using these glasses, my eyes would feel very strained, and my vision would be blurry sometimes when I got off the computer for a few minutes. I have not had any blurred vision eye, strain, or headache since wearing these glasses. The glasses are very comfortable.

## Questions & Answers

**Q: Will TrueDark Daylights glasses help with migraines or light sensitivity?**
A: Many users with photophobia or light-triggered headaches find relief by reducing exposure to fatigue-causing wavelengths from screens and artificial lighting. Polarized lenses reduce glare and UVA/B filter provides additional protection.

**Q: Do I still need Sunsets or Twilights if I wear Daylights junklight blocking glasses all day?**
A: Yes. Each lens plays a unique role. Daylights filter 75% of blue light while letting in healthy blue for energy and focus. Sunsets help you ease naturally into evening, and Twilights block 99% of junklight to mimic darkness and support deep sleep.

**Q: What is Junklight and how can it affect me?**
A: Junklight is the artificial light from screens, LEDs, and overhead lighting. Your brain treats light like a signal—the wrong light at the wrong time of day throws your biology out of rhythm. The result? Junk sleep, junk energy, junk focus.

**Q: When is the best time to use Daylights glasses to block junklight?**
A: Wear Daylights after getting some natural sunlight in the morning. Aim for about 30 minutes of daylight first—then use Daylights to block junklight from screens, LEDs, CFLs, and other artificial sources throughout the day.

**Q: What percentage of blue light should I be blocking during the day?**
A: Your brain needs some blue wavelengths during the day to stay alert and energized. TrueDark Daylights target only the disruptive wavelengths (380–500nm), while still letting in the beneficial light that supports focus, mood, and energy.

### ⭐⭐⭐⭐ Good blue blocking glasses
*by B***A on 21 March 2026*

Great blue blocking glasses. Fit well over glasses or by themselves. Light weight. I felt the lens wasn't perfectly clear. I guess none are but I decided to go with a different brand with slightly clearer lenses. I will only wear them at night for watching TV.
