How do you choose the right circadian glasses for you?
Don’t judge them only by how dark or red they look — check what wavelengths they actually block.
Let’s test Sleepaxa Red Sleep Glasses on a live spectrometer.
Here’s the light spectrum without the glasses.
Now, let’s place the Sleepaxa Red Sleep lens in front of the spectrometer.
You can see the difference — our Red Sleep lenses are designed to provide 100% blue and green light blocking up to 550 nm, helping reduce short-wavelength light exposure during your pre-sleep routine.
For best use, wear them around 45–60 minutes before bedtime, especially while using your phone, laptop, TV, or indoor lighting.
Choose your circadian glasses based on the actual spectral performance not just the lens colour.
