Photochromic Spectacle Blanks from Mexico
Photochromic spectacle blanks are pre-formed blanks with photochromic molecules that darken in UV light, designed for transition corrective lenses. They are curved but not optically worked, as they require grinding to a prescription. These blanks fall under tariff item 7015.10.00 as glasses for corrective spectacles, retaining their classification despite the embedded photochromic properties.
