Photochrmic Lens

DOUBLE-SIDED PHOTOCHROMIC COATING

Unique double-sided surface coating process and chromotropic layer evenly covers both lens sides. Normal photochromic coated lenses are only coated on the external surface, which doesn't always lead to ideal color depth and UV protecting effect.

Sunfilter UV+ double-sided photochromic coating lenses have deeper color and better UV protection through both-sided photochromic technology perceiving full-aspect light absorption.

UV++° PROTECTION AGAINST BLUE LIGHT

Imported UV++° monomer effectively absorbs high-energy blue light generated from digital electronic devices and outdoor natural light. As researched by anti-blue light expert Doctor. Funk from German Dresden University Medical Colleague, it protects against blue light scientifically and effectively, in a lens that is virtually clear.

INDOORS AND OUTDOORS PERFORMANCE

The proprietary combination of the double sided coating and in mass blue light dye makes the Sunfilter UV++°photochromic coating lens highly sensitive to UV exposure. Indoors the lens is transparent and changes according to UV strength when worn outdoors. The stronger the UV exposure is, the darker lens color will turn. Light transmittance will increase quickly when coming back indoors from outside activities. This quick darkening and fade back will provide customers with a comfortable wearing experience.
