NON-PRESCRIPTION LENSES

All of our non prescription glasses come with CR-39 blue light blocking lenses. This material is composed of plastic polymer commonly used in the manufacture of eyeglass lenses today. The big advantages of CR39 lenses over previous glass lenses are lightweight, and better shatter resistance.

PRESCRIPTION LENSES

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.

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.

NOTE: Blue light lenses are slighted tinted, could be yellowish, blue or green depending on the factory.

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). 

To clean your lenses, simply rinse them with a mild dish soap and lukewarm water, and dry them with a soft cloth. For day-to-day cleaning of light smudges, a few swipes of the pouch included in your case should do the trick. Please be careful to avoid using hot water on your lenses (especially if they are high-index lenses), as they can develop bubbles or cracks when exposed to high heat.

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 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 it can also be welded, brazed, and soldered.
