Wondering how dark our sunglasses are? Or what is the best lens darkness category to protect your eyes from the sun? All Roshambo sunglasses lenses are Sunglasses Category 3 in terms of darkness, which falls into line with the European standard for UV protective sunglasses and also meet regulated United States safety standards. All of our sunglasses also have polarized lenses, which provides 100% protection against UVA, UVB and UVC rays.
ARE DARK SUNGLASSES BETTER?
Did you know that dark sunglasses don't necessarily provide UV protection? The UV treatment applied to lenses does not cause them to appear dark or tinted. The dark or gray colored tint is to provide comfort to the eyes when outdoors, which is why we provide a sunglasses category 3 of darkness on all of our lenses - gray and mirrored lenses.
WHY ARE POLARIZED LENSES BETTER?
Polarized lenses reduce glare and eye strain, while still delivering 100% UVA/B/C protection. We take kids eye protection seriously: as much as 50% of lifetime UV damage to your eyes occurs before the age of 10 and is irreversible - causing terrible long-term ailments!
