This is our classic frame, with 3 tints to choose from.
Per Diem (yellow) - designed for daytime, in front of blue lit screens like laptops or under artificial blue lighting, such as offices with a lot of unnatural light, the Per Diem lens blocks 50% of the blue light spectrum, allowing you to receive some blue while blocking the most important parts, so that your sleep clock understands it is daytime.
These should not be worn in the presence of natural sunlight.
Soíree (orange) - Our most popular tint, the Soíree lens allows you to enjoy a night on the town and avoid the light that would otherwise interfere with sleep. This lens blocks 100% of blue light, from 400-500 nm, giving you sound sleep protection while the amber tint allows for the visual functionality you may require in the earlier stages of the night.
Because they block all of the blue light spectrum, the Soíree lens can be worn up until bed time.
De Nocti (red) - the ultimate nighttime glasses, the De Nocti lens not only blocks all of the blue light spectrum but 90% of the green spectrum too which affects sleep too, although not to the same degree as blue light.
Worn primarily in the last 2 hours before bed, the dark red tint gives your eyes a luscious tone that's similar that which you only see with fire.
