Grilamide raw material - cr39 organic lens

Uv400 protection - marked with ce

It does not contain bisphenol a (bpa).it does not harm your health.it is extra light.

Circadian balance glasses

The right light balance, the right rhythm.

The bilge karga circadian balance glasses help you maintain your natural biological clock by filtering screen exposure at any time of the day according to its colors.

• Yellow: balance the over blue light of sunrise and daytime.
• Orange: mimics the natural decline of daylight in the evening.
• Red: almost completely blocks out blue light before sleep.

Designed for more stable sleep, clearer focus, and a more natural rhythm.

Why grilamid?

The raw material grilamid natural, produced in switzerland, is resistant to impacts and does not break easily due to its flexible structure. it is antibacterial and hypoallergenic. the raw material grilamid natural is sterile.

Why cr39 organic lens?

Cr39 is 20 times more resistant to breaking than mineral glass. when it breaks, the glass pieces are not sharp, so there is no risk of injury.

Cr39 is the most well-known organic material. because it conducts heat very well, it evaporates much less than mineral glass. it stands out, especially for its lightness.

Bilge karga circadien series

Our body's biological clock has evolved to function according to the natural cycle of the sun for millions of years. however, in modern life, artificial lighting and digital screens can disrupt this natural rhythm. in particular, the intense blue light emitted by led screens can throw off our biological balance by sending "daytime" signals to our brain at the wrong times.

__t14__ is an advanced light management system developed to combat the artificial light conditions of the modern world. its performance is substantiated by independent laboratory reports. this is not a treatment device; it's designed to help you realign with your biological rhythm amidst the light pollution of modern living.

Daytime focus and visual comfort:

YELLOW LENS

It offers a solution that goes beyond regular yellow glasses during daytime hours.according to the fully accredited analysis reports, this lens provides a balancing of the general blue light spectrum (380–500 nm) at an average of __t17__.in the __t18__ range, it offers __t19__ level of protection, preserving color balance.

But its real success comes in the 480–490 nm band, which has a critical impact on the biological clock — it filters out about __t20__ of the artificial light peak in this range.this intelligent filtering does not create an environment dark enough to induce sleep; it simply removes the “digital noise.” the result is increased contrast and visual performance that lasts all day.

Blue light is the most scattered light in the atmosphere and within the eye. when yellow lenses filter out this blue light, the "haze" disappears, and the edges of objects appear sharper.

This lens is specially designed to rest your eyes without making you sleepy during the day. it blocks most of the light that strains the eyes (63%), but allows the beneficial part to pass through so as not to reduce your energy.

Evening digital de-load,

Evening active recovery: orange lens

You don’t have to go completely off the grid after dark. our orange lens provides an average of __t27__ of filtering across the blue light spectrum (380–500 nm) based on fully accredited test reports.

While blocking artificial light by __t28__ in the 480–490 nm band, which is a critical region for biological effects; it takes the protection shield one step further by offering extra filtering at __t30__ in the __t29__ range. this sensitive filtering bridges a "soft transition" between day and night. while you spend time in front of the screen, your body goes into rest mode in the background.

A deep and controlled transition into the night:

Red lens

This is the most densely filtering component in the series. according to fully accredited analysis reports, this lens goes beyond simply blocking blue and violet light. it extends the protective shield towards the green spectrum, achieving a very high blocking rate of __t32__ within the __t31__ range.

But the most significant difference is that it reduces the total light transmittance to the level of __t33__.this data proves that it physically reduces the ambient brightness by about __t34__.this low light level creates a dim and calm environment perception in the brain, even with open eyes, accelerating the mental relaxation before sleep.
