Do you wear sleep glasses in bed?
No. Sleep glasses are worn in the evening, not while you sleep. You put them on 1–2 hours before bed, keep watching, reading or scrolling, and take them off at lights-out.

Why before bed and not in bed?
Blue-rich evening light can suppress melatonin and push the body clock, and sleep, later. In the evening that light comes from the television, your phone and the lamps around you. Once the lights are out there is nothing left to filter, so the glasses come off.
Are they the same as a sleep mask?
No. A mask blocks all light while you sleep. Sleep glasses let you see, so you carry on with your evening while the lens changes the light.
What should they block?
The body clock is especially sensitive to short-wavelength light around 480–490 nm. SleepSpec blocks 98% of blue-green light across 400–520 nm. Colours look amber, and screens and text stay usable. Glasses to wear before bed has the timing in full.
