Lens guide
Orange glasses for sleep: do cheap ones work?
Some do, but you cannot tell from the colour or the price. Orange glasses range from pale tints made for daytime screens to deep-amber lenses made for the hours before bed. Look for a stated blocking percentage and a wavelength range that covers 480–490 nm. SleepSpec states both: 98% of blue-green light across 400–520 nm, for £29.99 with free UK delivery.

Why does the shade matter?
The colour you see is the light the lens lets through. A lens that removed most blue-green light would look deep amber, not pale yellow, so the paler the tint, the more of that light reaches your eyes. Pale yellow and light-orange lenses are often sold for gaming and daytime screens, where a near-normal view matters more. For the 1–2 hours before bed, choose a deep-amber lens.
What should a cheap pair tell you?
The same as an expensive one: a blocking percentage and a range in nanometres. The body clock is especially sensitive to short-wavelength light around 480–490 nm, so the range should cover that band. If a listing gives neither figure, you cannot tell what the lens filters. The UK buying guide has the full checklist.
Do orange safety glasses work for sleep?
They can, if the maker states what they filter. Safety glasses are made as eye protection first, so check the listing for a blocking percentage and range, and make sure they are comfortable for an hour or two on the sofa.
What does the extra money buy?
With SleepSpec you get:
- Deep-amber lenses that block 98% of blue-green light across 400–520 nm
- A 23 g frame with built-in nose pads and spring hinges
- A hard case, cleaning cloth, presentation box and instructions
- Free UK delivery and 30-day returns
SleepSpec costs £29.99 (normally £34.99).
What does the evening look like through deep amber?
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.
Take the glasses off for anything that needs accurate colour, and never wear them while driving.
When should I wear them?
Put them on 1–2 hours before bed and take them off at lights-out. See glasses to wear before bed for the timing in full.
