RA Optics has quietly become a staple in my sleep biohacking journey. I wear them nightly alongside my Joovv red light sessions, plus I’ve added Ocushield filters to all my devices. I even keep a separate pair for daytime—10+ hours on screens isn’t light work.
Since building this into my routine, I’ve been falling asleep faster and sleeping deeper. It’s like my body gets the signal now… time to rest.
Small changes, but they’ve made a big difference.
I love my new Ra Optics glasses! I can feel my whole face relax when I put them on!
There is a noticeable difference in my “winding down” process when wearing these lenses before bed. Your senses are seemingly warmer. I have noticed that I fall asleep easier after a short time of use. I recommend.
