Why use blue light blocking glasses?

Light pollution can disturb your body in several ways. Your body uses light of different colours to set your biological clock properly. Blue light for daytime and red light for evening. Artificial light and screens emit unnatural amounts of blue, green and violet light. Continuous exposure to it can disrupt your day-night rhythm.

Light pollution can also disturb your sleep. Blue light inhibits the production of the natural sleep hormone melatonin. Green and violet light do the same to a lesser extent. If you are still using bright artificial lights or screens in the evening, it is more difficult to fall asleep. Excessive blue light is also extra tiring for your eyes, which is annoying when you use computers for a long time.

Blue filter glasses protect against light pollution, which helps your eyes to relax and can improve your sleep.

Why use TrueDark Twilights Sunset Fairlane blue blocking glasses?

Blue light filter glasses are becoming more widely available. Their quality and effectiveness is still highly variable. TrueDark is one of the best brands currently available.

TrueDark blue filter glasses are recommended by Dave Asprey, the founder of Bulletproof and a well-known biohacker. He is also a co-founder of TrueDark.

Red to amber gradient glasses

TrueDark Twilights Sunset Fairlane blue blocking glasses are meant for the period after sunset, in which you start to finish the day. Twilights Sunset Fairlane lenses contain a colour gradient that ranges from red at the top to amber at the bottom. With these glasses, you can still do activities such as cooking and watching TV, while you protect your eyes from harmful artificial light.

The lenses stop 99% of blue light and 73-95% of green light! This makes the glasses an intermediate step between the TrueDark Daywalker with amber-coloured lenses and the TrueDark Twilight glasses with red lenses.

The patented TrueDark glasses are made of scratch-resistant polycarbonate and fully coloured.

Lightweight, classic frame

The frame is made of lightweight polycarbonate with a matte black finish. The frame has a classic look and gives wide coverage of the eyes.

The TrueDark Twilights Sunset Fairlane blue filter glasses come in a foldable hard-shell glasses case with a microfibre cleaning cloth.

  • Do not use these sleeping glasses while driving or operating heavy machinery or other operations that suffer from fatigue, change in depth of vision or changes in the colour spectrum.
