Screens aren't the problem. The specific slice of light they give off is. Freddie removes that slice and leaves the rest.
Lens curve: lab-measured transmittance. Spectral data: f.lux Software LLC, fluxometer.com (CC-BY 4.0). Bedtime limit: ≤10 melanopic lux before bed (Brown et al., 2022), assuming typical viewing brightness. Curves smoothed (5 nm) for display.
We Disagree.
After a long day, that last hour can feel like the only time that’s actually yours.
You should be able to spend it however you want, without worrying about your sleep in the process.
Put them on an hour before bed. Change nothing else.
Crafted from hand-polished acetate, the same material used in premium eyewear.
Pigment embedded into CR-39 lenses, not a coating that wears off.
Lenses are lab-tested for transmittance across the visible spectrum.
We believe every great day starts with a good night’s rest. Stop letting harmful light wreck your sleep.
Try Freddie risk-free for 30 nights and feel the difference.
They block the blue and green light that holds melatonin back in the hours before bed. That's the light your brain reads as daytime. Most people notice they wind down more easily within the first week.
Sleep has a lot of inputs. This is one of the biggest you can actually control.
Take them off when you turn off your last light. Once the lights are out there's nothing left to block, so set them on the nightstand and go to sleep.
Put them on 60 to 90 minutes before you want to be asleep. Earlier is fine too, most people just slip them on when they settle in for the night.
Leave them on until you turn off your last light and head to bed.
Yes, that's the whole idea. Keep scrolling, keep watching, keep doing your normal routine.
Freddie filters the light coming off your screens so you don't have to put them down. The only thing that changes is what reaches your eyes.
Yes, everything takes on a red tint. That's the filter doing its job, which means the blue and green light isn't reaching your eyes.
You'll still see clearly enough to read, scroll, and move around your home.
Over time people start to associate that shift with bedtime.
Standard blue light glasses filter ~10% of blue light, and they're built for daytime screen use.
Freddie is designed for evening use and blocks 99% of blue and green light, the wavelengths that hold melatonin back before bed.
If you wear contacts, you're all set. Put Freddie on right over them like any glasses.
Prescription lenses are something we're exploring for the future, but they aren't available yet.
Wear them for 30 nights. If they're not helping you wind down, send them back for a full refund.
