Production Flow Chart

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.

Progressive lenses are line-free multifocals that have a seamless progression of added magnifying power for intermediate and near vision.

Progressive lenses sometimes are called “no-line bifocals” because they don’t have this visible bifocal line. But progressive lenses have a significantly more advanced multifocal design than bifocals or trifocals.

Premium progressive lenses (such as Varilux lenses) usually provide the best comfort and performance, but there are many other brands as well. Your eye care professional can discuss with you the features and benefits of the latest progressive lenses and help you find the best lenses for your specific needs.

Using the peripheral defocus control technology, the power of the lens decreases from the optical center to the edge of the lens, which effectively reduces the peripheral hyperopia defocus phenomenon, thereby delaying the elongation of the eye axis and slowing down the development of myopia.

Optical software was used to calculate the imaging state of the lens when the chief ray was compensated by the dioptric power when the lens was projected obliquely, and the optimized design of the lens was carried out on the basis that the peripheral retinal imaging was in a myopic defocus state.

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.

What are progressive lenses?

Progressive lenses are no-line multifocal eyeglass lenses that look exactly the same as single vision lenses. In other words,
progressive lenses will help you see clearly at all distances without those annoying (and age-defining) “bifocal lines” that are
visible in regular bifocals and trifocals.
