Fold™ Folding sunglasses can be easily folded and tucked away for ultimate portability, while still maintaining a highly durable frame. With Fold™ Folding sunglasses, you don't have to sacrifice fashion for convenience. Simply wear, fold, unfold and wear again. Frame material Our FOLD eco frames are made from a unique plant-based resin derived from castor plant seeds. This natural bio-based material offers many desirable attributes, including lightness, flexibility, strength, and durability while being a low environmental impact substitute for standard petroleum-based products. We have deliberately used this resin to align with our objective to offer products that ensure sustainability and minimise global warming. Lens technology Our lens constructions are optimised to provide a variety of optical and impact-resistant benefits. We precisely align the finest polarised filters and finish our lenses with multi-layer UV Filters, Mirror coatings, and anti-scratch coatings. The end result is an artfully crafted lens that preserves colour perception and delivers optimized optical clarity and precision in all environments. 100% UV protection Our sunglasses offer 100% UVA and UVB protection. UV exposure can cause snow blindness (painful and upsetting damage to the front section of the eye) Exposure to UV has been shown to cause long-term ocular damage. It has been proven that UV exposure leads to an increased incidence of cataract and macula degeneration later in life. Finally, most of the annoying glare we experience comes from the UV and blue end of the visible spectrum. All of our sunglasses feature lenses that have surpassed British, European or American safety tests for optical clarity, impact resistance and sun protection. Base curve The base curve is the radius of the sphere measured from the back of the lens. Fold™ sunglasses have a 6 base lens curvature. Models that comprise a 6 base curve tend to be more flat relative to your face.
