Where to use it

For your evenings at home

Put them on when the day is done: while you cook, eat, read or watch a screen with the lights still on.

The red lenses are made for night-time use and visual relaxation. They block 99.14% of blue light, so the light from your phone, laptop, TV and lamps reaches your eyes warm and red instead of bright and blue.

Key features

Materials and weight

The frame is made of TR90, a high-performance material widely used in premium eyewear because it is light, flexible and durable.

The lenses are made of polycarbonate, a very resistant and lightweight material designed for long-lasting comfort and everyday reliability.

Thanks to this combination, the glasses weigh only 28.3 g, so they are comfortable to wear for long periods without pressing.

The problem

What blue light does to your body

From the surface of your eye to the clock in your brain, step by step.

Close-up of the surface of an eye

1

Your eyes blink less, so their surface dries out

On a screen we blink less, often only halfway. The film of tears thins and the surface dries: that gritty feeling by mid-afternoon.

2

The muscles that focus never get a break

A screen sits at one short distance for hours. The muscles that focus and align both eyes work without pause.

Blue light reaches the back of the eye, where your body clock is read

Special cells measure how bright the day is, and they respond most to blue light. Screens and LEDs are rich in it.

The signal goes straight to your brain's clock

At 11 pm, bright, blue-rich light can read as daytime, and melatonin, the hormone that tells your body it's evening, is held back.

5

So you fall asleep later, and the morning pays for it

In a study, people who read on a light-emitting screen before bed took longer to fall asleep and were less alert the next morning.¹

Night mode on one screen is not enough

The laptop, the TV and the ceiling light are all still on. Glasses change the light that reaches your eyes from every source at once.

  • 99.14%: of blue light blocked

Good to know

  • These glasses are not a medical device. They are not intended to diagnose, treat, cure or prevent any condition. If you have trouble sleeping or problems with your eyes, talk to your doctor or optician.
  • The red lenses make everything look red and darker: only about 26% of visible light gets through. They are made for the evening at home, not for driving.
  • These are not prescription glasses.
