Unworked Polycarbonate Spectacle Blanks
These are curved, hollow polycarbonate blanks designed specifically for grinding into corrective spectacle lenses. They fall under HTS 7015.10.00.00 as glasses for corrective spectacles that are not optically worked, meaning they have not undergone final surfacing or polishing. The material is injection-molded into lens shapes prior to optical processing.
CR-39 Semi-Finished Lens Blanks
CR-39 resin blanks are pre-formed, curved glass-like lenses for corrective eyewear, awaiting optical working such as grinding to prescription. Classified in HTS 7015.10.00.00 as they are hollowed or curved but not yet optically finished. These allyl diglycol carbonate blanks are standard for everyday prescription glasses.
High-Index Glass Lens Blanks
These thin, lightweight glass blanks with high refractive index (1.60-1.74) are molded for progressive or bifocal corrective lenses before surfacing. They qualify under HTS 7015.10.00.00 as unworked glasses for spectacles, bent or hollowed but not optically processed. Ideal for strong prescriptions requiring minimal thickness.
Trivex Lens Blanks for Eyewear
Impact-resistant Trivex polymer blanks, optically clear and lightweight, formed into spectacle shapes for corrective grinding. Classified under HTS 7015.10.00.00 as glass equivalents (fused silica per notes) that are hollowed but unworked. Superior to polycarbonate for aberration control in prescriptions.
Bifocal Semi-Finished Glass Blanks
Glass blanks with pre-molded bifocal segments for distance and near vision correction, awaiting final grinding. HTS 7015.10.00.00 covers these bent, hollowed forms not optically worked. Common for reading and driving glasses.
Progressive Addition Lens Blanks
Blanks with seamless gradient zones for continuous vision correction, pre-formed but unground for spectacles. Under HTS 7015.10.00.00 as corrective glasses not optically worked, despite complex molding. Preferred for presbyopia without visible lines.
