The surface abrasion characteristics of 109 pair of spectacle lenses were evaluated after 1 yr of wear at Nellis AFB, Nevada. One lens of each pair was an abrasion-resistant coated Lexan while the other was uncoated CR-39. Data showed that the hard-coated Lexan lenses are more abrasion-resistant than uncoated CR-39 lenses. Originator supplied key words include Polycarbonate Lenses Abrasion-Resistant Coating Plastic Lenses Ophthalmic Lenses.
