Semi Finished Lenses
Semi-finished lens is the raw blank used to produce the most individualized RX lens according to thepatient's prescription. Different prescription powers request for different semi-finished lens types or base curves.
The semi-finished lenses are produced in a casting process. Here, liquid monomers are first poured into moulds. Various substances are added to the monomers, e.g. initiators and UV absorbers. The initiator triggers a chemical reaction that leads to hardening or "curing" of the lens, while the UV absorber increases the UV absorption of the lenses and prevents yellowing.
Detailed Images
When Photochromic lenses are exposed to UV light, trillions of photochromic molecules in the lens begin to change structure. This reaction is what causes the lenses to darken.
All lenses that adap to light use photochromic molecules; the superiority of Convox photochromic technology lies in our exclusive, patented formulas. These molecules constantly and smoothy recalibrate so the optimal amount of light reaches your eyes whether you're in bright sunlight, under cloud cover or indoors.
Indoor
Restore the color of the transparent lens under normal indoor environment and maintain good light transmittance.
Outdoor
Under sunlight, the color of the color-changing lens becomes brown/gray to block ultraviolet rays and protect the eyes.
Product Feature
One lens has three functions, intelligent discoloration.
The lens adopts the optical fiber rapid discoloration technology to make rapid adjustments to different light rays, so that the wearer can enjoy the pleasure of entering the corresponding environment under suitable discoloration conditions. It changes color instantly under the sun, and the darkest is the same dark color as sunglasses, while ensuring the uniform color change of the lens, and the color of the center and the edge of the lens are consistent. Matching aspheric design and anti-glare function, it is clearer, brighter and more comfortable to wear.
