Block Blue Glasses — Blue Light Blocking Glasses for Screens & Sleep

Block Blue Glasses filter the short-wavelength light coming off your screens and LED lighting — the part of the visible spectrum most closely tied to alertness, and to when your body starts producing melatonin. Four frame colours, three lens tints, one price.

Pick your lens by the time of day

Tint is the whole decision. A warmer, darker lens cuts more of the blue and blue-green range, which makes it better for the evening and worse for anything where colour accuracy matters. All three lenses are available in every frame.

Yellow — daytime screen work. The lightest filter of the three. Takes the edge off glare and long monitor sessions while keeping colours close enough to normal for everyday work.

Orange — evenings. A stronger filter for the two to three hours before you want to be asleep, when blue-rich light from a TV, laptop or phone is most likely to push your body clock later.

Red — late nights and shift work. The heaviest filter, for night shifts, reading in bed and 3am wake-ups. Colours shift noticeably, which is the point: red is for winding down, not for accurate work.

Frames

Grey, black, tortoise and clear, all in the same lightweight design and all available with any of the three lens tints. Non-prescription, and sized to suit most adult faces.

An honest note on what these do

Blue-blocking lenses are worth trying if late screen use is affecting your sleep. Short-wavelength light in the evening is a well-established signal that delays melatonin release, and filtering it is a low-risk thing to try.

They are less convincing as a fix for digital eye strain. Most eye-care bodies now attribute screen fatigue to prolonged focusing, glare and reduced blinking rather than to blue light itself — so breaks, screen brightness and blink habits will do more for tired eyes than any lens will.

Common questions

Do these fit over prescription glasses? No — they are standalone non-prescription frames, not fitovers.

Can I drive in them? Yellow lenses are fine in daylight. Do not drive at night in orange or red lenses.

Which lens should I start with? If sleep is the goal, orange. If it's all-day screen comfort, yellow.
