I love my RA Sunset Glasses! Best investment ever, my sleep is great and my eyes don't hurt anymore. It takes about a couple of days to adjust, but wouldn't trade this for anything else. I love love love them. ❤️❤️❤️❤️
I have loved using these along with my daylight lenses. I am often working on my laptop till late and these take a huge load off of the eye strain that I experience and make it a much more natural transition to sleep when I am done working. Definitely recommend these.
Ive been struggling with sleep, part of it being screen time before bed, and not being able to relax my body.
Now these glasses changed that entirely. I notice a significant decrease off stress in my eyes from screens, and my entire body gets relaxed. I highly recommend these for everyone, no matter who.
After 14 days of usage, i still feel the same effect.
love these. Got daylight sol glasses from you too! Also super stoked for those! U guys have quality products 100% thank you
with these glasses. Nighttime reading on my iPad and tv watching is much easier on my eyes. I even believe I am sleeping more soundly.
