Diesel Unisex Plastic Frame Model 0044 £99.50
	Plastic CR-39 with Hardcoat Our Standard Lenses, these lenses are the ideal choice for most single vision prescriptions because they are so much lighter and less breakable than glass lenses. Plastic lenses are great for prescription sunglasses due to their tintability factor. Clear Polycarbonate Polycarbonate is a unique material that was originally used primarily for industrial safety glasses because of its very high impact resistance qualities. It is now used for children, sports wearers, rimless frames, or anyone requesting greater impact resistance in their lenses. All polycarbonate lenses automatically come with ultraviolet protection, and hardcoat, 20% thinner then CR39 and up to 30% lighter. Hi-Index 1.67 These lenses are thinner and lighter than they have ever been before by using the highest index of refraction at 1.67 and a most advanced material. High prescriptions no longer mean thick, chunky lenses that can only be glazed into heavy frames. 1.67 lenses are up to 45% thinner than regular plastic lenses! Wes upply a MAR with these lenses as standard. Hi-Index 1.74 Lenses Hi-Index 1.74 lenses are the thinnest, flattest, and most cosmetically appealing lens ever developed and deserves the best of all technologies including the most advanced anti-reflective (AR) lens treatment. These lenses are nearly 50% thinner than 1.50 index plastic and 13% thinner than 1.67 index, offering you the ultimate in technology and cosmetics by reducing the "eye-shrinking" effect that many high prescriptions have. High index lenses have flatter curves than their lower-index counterparts for a reduced lens profile. A flatter curve, however, can cause off-axis blurred vision. To compensate, the 1.74 lens incorporates optical aspheric technology into the lens design. Not all aspherics are created equal. We have chosen only the industry's most advanced optical performance in a flat design while preserving beautiful cosmetic appeal, comes with a MAR coating as standard.
