Anti-Reflective Coated Glass Lenses
Anti-reflective coated glass spectacle lenses, unmounted and optically worked from high-index glass. The multi-layer coating reduces glare and enhances light transmission, making them suitable for night vision and general eyewear. They are finished lenses, not blanks, and are not designed for hazardous work.
Aviator-Style Tinted Glass Lenses
Aviator-style tinted glass spectacle lenses with gradient gray/green tint, combining prescription correction with light reduction. These unmounted lenses are optically worked from neutral-density tinted glass, designed for pilots and outdoor use. They are finished products, not blanks.
Bifocal Glass Spectacle Lenses
Bifocal glass spectacle lenses with distinct distance and near vision segments, fused or molded into single unmounted lenses. These are optically worked from crown glass, designed for presbyopia correction. They are finished lenses, not unfinished blanks.
Crown Glass Single Vision Lenses
Crown glass single vision lenses with low dispersion (index 1.52), ground and polished for everyday correction. These unmounted lenses are optically worked and available in spherical powers. They are finished lenses, not blanks.
Flint Glass Myopia Control Lenses
Flint glass myopia control lenses with peripheral defocus zones, designed to slow myopia progression in children. These unmounted lenses are optically worked with concentric treatment rings. They are finished lenses, not blanks.
High-Index 1.8 Glass Lenses for Eyeglasses
High-index 1.8 glass spectacle lenses for strong prescriptions, minimizing thickness while maintaining optical clarity. These unmounted lenses are made from dense flint glass and precisely ground. They are finished lenses, not blanks.
Photochromic Transition Glass Spectacle Lenses
Photochromic glass spectacle lenses that darken automatically under UV light, made from specially formulated glass and ground to prescription. These unmounted lenses are optically worked and finished. They are not designed for hazardous work.
Polarization Glass Spectacle Lenses
Polarization glass spectacle lenses with a polarizing film embedded between crown glass wafers, reducing glare for outdoor activities. These unmounted lenses are optically worked and finished. They are not safety lenses for hazardous work.
Prism Glass Spectacle Lenses
Prism glass spectacle lenses incorporating prism diopters to correct eye alignment disorders. These unmounted lenses are optically worked with base-in/out prism ground into the prescription surface. They are finished lenses, not blanks.
Progressive Addition Glass Lenses
Progressive addition glass lenses with a seamless power gradient from distance to near, ground into high-quality optical glass. These unmounted lenses are optically worked and finished. They are not designed for hazardous work.
Reading Glass Magnifier Lenses
Reading glass magnifier lenses with +1.00 to +3.50 spherical power for presbyopia correction, featuring aspheric design. These unmounted lenses are optically worked from crown glass. They are finished lenses, not blanks.
Scratch-Resistant Glass Spectacle Lenses
Scratch-resistant glass spectacle lenses with hard carbon or diamond-like coatings, enhancing durability for daily wear. These unmounted lenses are optically worked from crown glass. They are finished lenses, not blanks.
Trivex Glass Hybrid Spectacle Lenses
Trivex glass hybrid spectacle lenses with a Trivex polymer core and glass outer layers, offering impact resistance and optical clarity. These unmounted lenses are optically worked to prescription. They are finished lenses, not blanks.
Uncoated Glass Spectacle Lenses
Uncoated glass spectacle lenses, basic plano-convex or concave lenses from optical crown glass, designed for prescription correction. These unmounted lenses are optically worked and finished. They are not designed for hazardous work.
