The Alchemist leaves no stone unturned in the quest for discovery. What others consider impossible, they consider a worthy challenge. These round lens eyeglasses have an extra-lightweight construction for comfortable all-day use. The temples and frames are crafted with corrosion-resistant nickel silver and cellulose acetate. The lenses are made with triacetate cellulose to provide the best optical clarity. The lenses also have a scratch-resistant and anti-glare coating, and they offer 100% UV protection. Unlike many blue-light lenses that look yellow, ours are virtually clear — giving you all the protection you need with a crystal-clear view. A must-have for every screen lover. The Alchemist has discovered the mix of materials needed for eyeglasses worth their weight in gold.
