Why use blue light filter glasses?

Blue light affects your performance. Your body uses light of different colours to set your biological clock properly. Blue light for daytime and red light for the evening. Artificial lights and screens emit a lot of blue light. Being exposed to it all day can disrupt your day-night cycle. Excessive blue light also puts extra strain on your eyes, which can become an issue when you use your computer for a long time.

So consider using eye strain glasses if you spend a lot of time inside or working with your computer. These glasses can also help when you work shifts and are extra sensitive to bright light during the day.

About TrueDark glasses

Blue light filter glasses are becoming more widely available. Their quality and effectiveness are 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.

Colourless lenses for inconspicuous protection

TrueDark makes blue light blockers with tinted lenses for the most effective protection against excessive blue light. However, coloured lenses are not suitable for every situation. For some tasks it is important that you see colours accurately. Also, other people may find it strange or inappropriate that you wear coloured glasses. In these situations, the colourless lenses of the Daylights Tortoiseshell Pro are the perfect solution!

TrueDark Daylights Tortoiseshell Pro blocks 40% of blue light. You need some blue light during the day to properly set your biological clock. These glasses help to block much of the excessive blue light from screens and artificial lighting.

The patented TrueDark glasses are made of scratch-resistant polycarbonate. The colourless lenses do not lose their effectiveness when scratched. Other brands of blue light filter glasses often use colourless lenses with a coloured coating. They are not as effective when they are scratched.

Mottled, streamlined acetate frame in two colours

The frame is made of lightweight, mottled acetate with brown or grey. The spring hinges ensure a good fit. The frame has a streamlined look and provides wide coverage of the eyes.

The TrueDark Daylights Tortoiseshell Pro blue light filter glasses come in a foldable hard-shell glasses case with a microfibre cleaning cloth.
