We take our testing seriously.

We test every batch of lenses to ensure we’re providing the best sunglass lenses on the market. If they don’t pass our standards… they’re never sent out.

COLTS Trained Testing Lab

We are proud to have completed training from COLTS, an industry leader in lens testing and standards since 1997.


Scratch Resistance

Lenses go through a lot. To ensure scratch resistance standards, we repeatedly run a gravel material across our lenses and compare the clarity before and after. 


Coating Durability

The average person can wipe their sunglasses around 4,000 times in one year. We test 5x that amount of microfiber passes in 1.5 hours to make sure our coatings last.


Saltwater Resistance

Salt water erodes coatings and peels back lens layers overtime, so we boil our lenses in it to make sure they stand up to fishing trips and beach days.



Lenses are scored and subjected to saltwater humidity at temperatures exceeding 180°F and then rapidly cooled to simulate environmental wear and tear. One cycle simulates 6 months of product use in the elements.



Fuse tests each of our lenses at standards that are 60% clearer than industry standard. That means you can expect crisp, clear vision no matter what lenses you choose.


Impact Resistance

Every pair of Fuse Lenses is shatterproof Polycarbonate, so you can feel safe behind your sunglasses.
