Blue Light Blocking Glasses

Blue blocking glasses filter the short-wavelength light that screens, phones and LED bulbs put out — the part of the visible spectrum most closely linked to alertness, and to when your body starts producing melatonin. Dermfix has worked in phototherapy for more than 20 years. The same attention to wavelength that goes into our red light panels and narrowband UVB lamps is what we bring to choosing lenses.

Which lens colour should I choose?
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 come in the same frames, so choose by the time of day you'll wear them.

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

Orange — evenings. A stronger filter for the two to three hours before bed, 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 lenses are for winding down, not for accurate work.

Do blue blocking glasses actually work?
It depends what you want them for, and it's worth being straight about this.

The evidence for blue-blocking lenses preventing digital eye strain is weak. Most eye-care bodies now attribute screen fatigue to prolonged focusing, glare and reduced blinking rather than to blue light itself. Regular breaks, lower screen brightness and blinking more will do more for tired eyes than any lens.

The evidence for evening light and sleep is stronger. Short-wavelength light in the hours before bed is well established as a signal that delays melatonin release, and filtering it is a reasonable, low-risk thing to try if you're on screens late. That's where an orange or red lens earns its place.

Glasses are one part of a wider picture. Dimming household lights in the evening, turning screen brightness down, and getting bright daylight in the morning all pull in the same direction.

The Dermfix range
Block Blue Glasses come in four frame colours — grey, black, tortoise and clear — each available with a yellow, orange or red lens. Block Blue Glasses Gamer use a gaming frame in the same three lens options.

Every pair is non-prescription, sized to suit most adult faces, and ships with a foldable carry case and a microfibre cleaning cloth. Orders ship from our EU stock.

Common questions
Can I wear them over prescription glasses? No — these are standalone non-prescription frames, not fitovers.

When should I put them on? Yellow whenever you're at a screen. Orange or red about two to three hours before you want to be asleep.

Can I work or game in the red lens? You can, but colours shift a long way. Use yellow for anything where you need to judge colour.

Are they safe to drive in? Yellow lenses are fine in daylight. Do not drive at night in orange or red lenses.

How are these different from red light therapy? Opposite jobs. Red light panels deliver light to your skin. Blue blocking glasses take light away from your eyes.
