Fritz Hollwich was a pioneer in the field of light research. He discovered the "non-visual" pathways of the optic nerve, proving beyond a shadow of a doubt that light passing through the eye controls a majority of biological systems, including our circadian rhythm, sleep/wake cycles, liver function, kidney function, heart function, brain function, and the production of key hormones and neurotransmitters throughout the entire body.

They really work

These glass do exactly what Ra claims they do. Price was the only reason I gave 4 stars. There are other brands for way less that will also filter blue light. I’m happy with these but I will look elsewhere for daylight glasses solely based on price point

Extremely High Quality, Amazing Customer Support

Normally, I don't do reviews but Ra-Optics had pretty exceptional service. I ordered both Fritz Sleep and Fritz Screen lenses, and they were both very nice. The sizing on the Fritz was a little too small for my liking, so I chose to do an exchange for the Maxwell. The exchange process was super smooth and fast. I already have both Maxwell glasses and have been loving them. I noticed I slept better the first night of using the sleep glasses after sunset. Overall great quality product and fantastic customer support.

RA OPTICS’ Products never disappoint

Was so happy with my day lenses that I made a second purchase of night lenses. RA over delivers again, I also purchased the Light Diet course and am anxious to go thru the material. Thank you again for the health education, quality products and service.

Thank you so much for your kind words, Peter! We are so grateful that you are benefitting from our products. Please do not hesitate to reach out if we can be of assistance.
