Who should wear blue light blocking glasses?

Students, office workers and gamers. Basically people who sit in front of a computer all day, who have trouble sleeping, or who suffer from eye strain or eye irritation from looking at a computer or mobile screen for too long.

What lenses do you use?


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.


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.

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). 

What percentage of blue light is blocked?


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).


Kooper +Game® technology blocks 70% of blue light for better protection and optimal performance.

NOTE: Blue light lenses are slightly tinted, could be yellow, blue or green depending on the style.

Do you offer prescription and reading glasses? 

Yes! We do offer prescription glasses (single vision) and reading glasses with sphere values from +/-6.00 to +/-6.00. Please add "Prescription or Reading" to cart when ordering from any product page. Please note that these orders require 4 - 8 business days for processing.

For more information please visit our prescription page.

How can I clean my lenses?

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.

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 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.
