Are blue light glasses worth it?
For sleep, yes, if you choose the right kind. Clear blue light glasses are made for daytime screens and filter only a fraction of blue light. Deep-amber sleep glasses are made for the 1–2 hours before bed, when blue-rich light can push the body clock, and sleep, later.

What is the difference between clear and amber lenses?
Clear lenses keep colours normal, which is why they let most blue light through. A lens that removes most blue-green light has to look deep amber. SleepSpec blocks 98% of blue-green light across 400–520 nm. Colours look different while you wear them, and screens and text stay usable.
Are blue light glasses a scam?
Not if the pair says what it blocks. Look for a blocking percentage and a wavelength range. A listing that gives neither leaves you guessing. How to choose blue light glasses for sleep has the checklist.
What do you get for the price?
SleepSpec costs £29.99 (normally £34.99), with free UK delivery and 30-day returns. In the box: the glasses, a hard case, a cleaning cloth, a presentation box and instructions.
