At the high end of sunglass technology, polarized lenses not only reduce glare and improve sharpness, they also filter all disturbing reflections coming from horizontal surfaces on land (road, grass), water (sea, lake, wet soil) as well as dashboard reflections on windshields. Drivers, sportspeople, fishermen and many others will confirm: polarized lenses are unequaled.

The ophthalmic lens market has been focused on delivering the right prescription lens up to now. In other words, lens manufacturers have sold corrective lenses to patients. However, times have changed and consumers are not satisfied with their vision correction only.

RemiMount-OC is an optically clear double-sided, pressure-sensitive mounting adhesive with two polyester film release liners. The optically clear adhesive is specifically designed for face mounting graphic images. It has been used extensively in back-lit applications using substrates such as Plexiglas and/or other transparent products. The high quality optically clear adhesive enables this product to be used for permanent face mounting to glass, holographic lenses, and a variety of other substrates that require maximum clarity with a permanent bond. It is also available with a removable adhesive system.

Optically ClearAdhesive film

But until now, the only polarized technology available was based on the insertion of a polarizing film into a sandwich of two lenses, glass or plastic, meaning thicker lenses, complex- thus costly- manufacturing processes, and the risk of delamination (by friction and wear, sweating, or thermal chocks).

Installation of 7 Inch Depth, 8ft to 16ft Window Sill (Included Materials). Price is determined on a per unit basis.

When traditional polarized technology (Polarized film) is used between 2 wafers, it reveals severe distortion coming from the stress of the lenses while PolarCoatTM Polarized coating applied on the convex or the concave lens surface provides uniform polarized function with outstanding optical performance.

This material is so thin that it doesn't completely adapt 2 pieces of 1/8 acrylic together without some minor defects. And if there are any tiny particles, it will leave a void in that area, also the cover sheets are pretty hard to remove, and you have to be insanely careful not to trap bubbles while adhering. We had to rub this down mm by mm to avoid bubbles.

Together with PolarCoat™, Chemilens is moving to the world of Polarized lenses where we will bring new experience for eyes comfort.

In addition, Polarized lenses with conventional film are not very good for Rimless or semi-rimless frames while PolarCoatTM shows excellent fitting performance.

1. The surface of the substrate is first chemically treated, then mechanically brushed in a specific way to determine the future orientation of the molecule chains 2. The Polarizing Dye Solution (PDS) is applied  3. Drying stage, during which the self-alignment of PDS molecules creates the polarizing effect 4. Chemical encapsulation of the polarizing layer 5. Primer with strong adhesive properties 6. Scratch-resistant protective layer (onto which an anti-reflective layer can also be applied)

At Chemilens, we believe that we are going to the new age where eyeglasses are not only for vision correction but also for the patients comfort. Chemilens is now transforming ourselves from a corrective lens provider to the provider of a new experience for eye comfort. We want to be the company which provides a new experience of human eye comfort to all the people, whether they need vision correction or not.

Traditional polarized lens thickness is not so good due to the different elements (Wafer + Polarized film + wafer) while the PolarCoat™ technology gives the advantage to maximize the lens thickness for any type of prescriptions including more severe prescriptions. The patient will take advantage of this as the edge thickness will be minimized. It’s a key advantage for a company like Chemilens which is already as of today the world manufacturer leader for 1.6 and 1.67 clear lenses.

Calculation of Extinction RatioThe extinction ratio is a parameter that quantifies the effectiveness with which a polarizer eliminates light polarization.

Thanks to PolarCoat™ patented technology, the culmination of several years of research and through testing, lens manufacturers licensed by Corning can now apply a surface treatment with 99% of polarization efficiency (PE). This new coating, launched in early 2010, is applied on the backside of plano sunglass lenses. In the near future, it will be available for the front-side treatment of semi-finished prescription lenses and of bi-refringent materials such as polycarbonate and nylon.

Last but not least, Chemilens ambition with PolarCoat™ is not only to penetrate the Polarized market for prescription lens but it’s also to become a new premium Polarized supplier for sun lens.

For this reason, Chemilens has decided to enter into the “Polarized lens” world to become a key manufacturer of Polarized lenses. Corning PolarCoat™ technology matches perfectly with our philosophy. Polarized lenses have been on the market for a long time and theoretically it’s considered as one of the best ophthalmic lenses for human eye health. However, it was also obvious that using the current Polarized Film technology was bringing some technical limitations. With the new innovative Corning Polarized Coating Technology (PolarCoat™), we can enter into the small world of the Polarized lens manufacturers with a strong added value and look to the future with confidence.

Adhesive: Ultra clear permanent acrylic adhesive has excellent chemical, humidity, and temperature resistance. NPL has been specifically developed for clear film applications requiring excellent optical clarity.

At Mido 2013 Corning and Chemi have officially announced their partnership for the launch of PolarCoatTM, the Corning polarizing coating technology.
