Charlie +Blue Light®
We spend +12 hours a day in front of digital screens. Computers, mobile phones, and tablets emit blue light that can strain your eyes, cause headaches, and disturb your sleep.
From classic to contemporary styles, our frames give you the ultimate comfort by being flexible and lightweight. We’ve created unique screen glasses that give you exceptional benefits.
All orders include a PU leather case, designed to prevent scratches and damage, a microfiber cleaning cloth for your lenses, and a dust bag.

Frequently Asked Questions
We want to protect your eyes in the best possible way, which is why we also include 100% UVA and UVB invisible filters to the delicate eye area, so your vision gets the comfort and protection it requires.
Who needs Kooper?
People who sit in front of a computer all day, who have trouble sleeping, who suffer from eye strain or eye irritation from looking at a screen for too long, who work in an office or school environment, or who play video games every day.
What percentage of blue light is blocked?
Blue Light Lenses: Kooper +Blue Light® technology blocks between 35% - 40% of blue light, providing clearer vision and comfort for your eyes. Kooper lenses are engineered to filter some of the highest energy wavelengths of visible light (400-440 nm).
Gaming Lenses: Kooper +Game® technology blocks 70% of blue light for better protection and optimal performance.
What are the dimensions of the glasses?
When you go to any of our product pages, you can find the size under the tab "General Information." When you click on the numbers, you can see an example to get a better understanding of these measurements. These numbers correspond to: Lens Width (mm) - Bridge Size (mm) - Temple Size (mm).
How can I submit my prescription?
We use High Index 1.56 HD lenses for all single vision prescriptions. Our high-quality aspheric lenses are thinner and lighter than polycarbonate lenses, making them optically superior. They also include 100% UVA/UVB protection, anti-reflective coating, anti-smudge, dust repellent, and water repellent treatments as standard.
We offer single vision and reading lenses with sphere values from +/-4.00 to +/-4.00.

What are your glasses made of?
We use three different materials for our frames:
TR-90: It is a type of nylon (plastic) material, it can be found with a soft or rubbery texture or a strong, plastic-type texture. They are very hard, but flexible.
Polycarbonate (Plastic): Polycarbonate is a naturally transparent amorphous thermoplastic. It also has a very good heat resistance and can be combined with flame retardant materials without significant material degradation.
Metal Alloy: Alloys are metals with other elements added to improve properties like strength or stiffness. This alloy is strong and can also be welded, brazed, and soldered.
