Amber glasses for sleep: what to look for
Amber glasses for sleep are tinted glasses worn for the 1–2 hours before bed to filter blue-green light from screens and indoor lighting. The colour alone tells you little, so look for a stated blocking percentage and wavelength range. SleepSpec’s deep-amber lenses block 98% of blue-green light across 400–520 nm and cost £29.99 with free UK delivery.

What do amber glasses do for sleep?
Blue-rich evening light can suppress melatonin and push the body clock, and sleep, later. The body clock is especially sensitive to short-wavelength light around 480–490 nm. An amber lens filters that light before it reaches your eyes, so you can keep watching, reading or scrolling. Better sleep is not guaranteed, and individual results vary.
How do I tell a sleep lens from a tinted one?
By the figures, not the shade. A 2025 optical analysis of 26 commercially available glasses described properly selected and timed blue-blocking glasses as a potentially low-cost tool for supporting sleep and circadian health. It did not test SleepSpec.
Selecting properly means checking for a blocking percentage and a range in nanometres that covers 480–490 nm. SleepSpec states both: 98% across 400–520 nm. The UK buying guide has the full checklist.
Are orange glasses for sleep the same thing?
Usually, yes. Sellers use “amber” and “orange” loosely for the same family of tint, and one brand’s orange can be another’s amber. Compare the stated percentage and range, not the name. SleepSpec calls its lens deep amber. Dark-red lenses are a different choice: see amber, red and clear lenses compared.
What does everything look like through amber lenses?
Strongly amber. Colours look different, while screens and text stay usable. Your eyes adjust within a few minutes, much as they do with tinted sunglasses, and the view starts to feel normal. SleepSpec’s deep-amber sleep glasses preserve more natural colour than dark-red lenses.
Take the glasses off for anything that needs accurate colour, and never wear them while driving.
When should I wear amber glasses?
Put them on 1–2 hours before bed and take them off at lights-out. They are for the evening, not for all-day wear. See glasses to wear before bed for the timing in full.
