Nate Sleep Makes for Great Sleep!

These glasses are awesome, and after a few weeks wearing them consistently after the sun goes down, I have noticed an improvement in my sleep pattern. I can also tell a huge difference in eye strain when looking at any screens with these glasses on, especially after the sun goes down. You can purchase these glasses with confidence, you won't be disappointed!

Best BLB Glasses on the Market!

I´ve tried a number of BLBs before deciding to give reoptics the chance (as I´m from Germany, tax and shipping is about half the price, what makes them kinda expensive for me) and I wish I did it earlier!

Lost my first glasses on vacation after using them almost 2 years and immediatley felt thr difference - the week until I received the package with the new order was really difficult for me and remembered me of the days before using a good BLB (real problems iwth getting to sleep every night).

Happy with the new Nate Sleep Glasses - even better than the model I bought 2 years ago (not the glasses, but the quality of the product itself and its design really upgraded in the time between).

I ordered the Popp Screen for work as my work environment calls for me to work indoors in front of screens and stark fluorescent lights all day. In addition, I ordered the Fritz Sleep Glasses; I was falling asleep as soon as I put them on at night; fell asleep within 10-15 minutes of putting them on. I noticed the next day that I had no interruptions while sleeping at night, and I felt well rested. I would definitely recommend this to anybody; it will benefit them greatly! Thanks Matt and the entire RA Optics team for your hard work and dedication!
