Intro Series For the Intro series we have focused on polarisation and comfort. We introduce people to the Leech experience, but doesn’t offer the full leech performance and design experience. For the Intro segment we have chosen TAC-lenses. They’re the lightest material for polarized lenses, which provides great comfort. Technical features in the Intro series Light and cool sunglasses that you can use both for fishing and wearing in town. Black with a little red details make them really nice. With the Premium Sight lens, you get high quality polarization here and since the lenses are very light, these sunglasses are very light. Nice for those who wear the glasses for a whole day. With the copper lens that is a little brighter, you get glasses that work in both sunny and overcast weather. Description Polarized Triacetate Cellulose (TAC) By injecting the polycarbonate material around the polarized material we create these high-quality lenses. Polycarbonate is a durable material and very hard to break. PC Lenses offer high clarity and the efficiency of the polarization is 99% Premium+ lens The advantage of Premium+ lenses - more sharply focused vision. Contours become clearer, perceived as considerably more relaxing and less fatiguing. In other words, these spectacle Premium+ polarized lenses don’t just protect your eyes against the sun – they also ensure improved vision without irritating glare. 100 % polarized, UV protected, bullet proof and shatter safe lenses with a newly developed hard coating for an even longer lifetime. Gray Lens Gray lenses are great for sunny days, as they offer light reduction and do not distort color like other lenses. Furthermore, these sunglasses prevent eye fatigue. Fishermen who fish in rivers that have grey bottoms should opt for grey glasses Scratch-resistant coating In the face of all the advancements in eyeglass lens coatings, eyeglass lenses are still not scratch proof – not even glass lenses. However, the Leech eyeglass lenses are treated front and back with a clear, hard coating which make it much more scratch resistant. Ultraviolet treatment UV400 This coating keeps the sun’s UV rays from harming your eyes. 100 % UVA, UVB and UVC Protection.
