It should come as little surprise that the Popular sunglasses from FIREFLY are one of our best-selling unisex models. Available in a range of eye-catching colourways and patterns, these shades complement just about every style and outfit. Function also matches form thanks to the versatile high-performance S3 filtered polycarbonate lenses with 100% UV protection.
All sunglasses are tested according to EN 174, determining the degree of light transmission (translucence) in the visible range, then being classified into filter categories.
S3 = 8-18%, very dark filter. Strong glare protection and high UV protection.
