How Does nanoCLEAR AR Perform in Ocean Climates?

We are often asked how nanoCLEAR™ AR performs in humid beach city climates as compared to vacuum AR. Well, nanoCLEAR AR and vaccum AR vacuum AR (whether it’s Crizal™ or some other brand) have very different failure modes. In the better vacuum AR stacks, craze is the root cause of most failures and patient returns. With the nanoCLEAR AR lens, its essentially impossible to induce craze.  As a result, our AR is damaged far less in boiling water and salt water tests than vacuum lenses

With vacuum AR on a plastic lens, the thermal expansion rates are vastly different between the AR and the lens. Since the AR layers are also brittle, they tend to fracture under the stress created when the lens heats up and expands. Once that happens, contaminants work their way into the stack more easily and can cause delamination. Even if delamination is avoided, craze typically causes haze, so once it’s severe enough that will lead to a returned lens as well.

Since our nanoCLEAR AR uses plastic binders and nanoparticles, the thermal expansion rates of the AR and lens can be matched, which eliminates craze failures. That’s not to say we never have failures, all AR can be damaged by patients, however, nanoCLEAR AR performs well in hot, humid coastal regions. Just ask our customers in Miami, Puerto Rico and the Caribbean!

Optical Dynamics Introduces amplifEYE Monomer

Eye Mobile Expands Digital Lens Lab

Eye Mobile, located on the island of Antigua, expanded their Q-2100 Digital Lens Lab to accommodate their growing business. With additional equipment, production volume is increased to meet their growing demand for clearLIGHT, sunSMART, ultraSUN, blueVIEW, amplifEYE, and nanoCLEAR AR.

Launched in 2007 Eye Mobile started out as just that, a first of its kind vision care provider not limited to an office space. As the operation’s tag line indicates, Eye Mobile “brings vision care closer to you.” Utilizing digital technology, patients obtained a comprehensive eye examination in the comfort of their own home, office or even at school. And the services weren’t limited to Antigua alone, but Barbuda, St. Kitts, Nevis and Montserrat as well.

By 2012, a second market was seen with the need to locate a branch downtown. Many a cruise ship passengers would come to them having lost a contact lens while swimming, desperately needing another, while others who had broken their glasses needed another pair quickly. Located on Redcliffe Quay waterfront, the branch was modernly designed and convenient for persons living and visiting St. Johns.

As mentioned on their Facebook page, “Even more intriguing was the speed at which the company can provide service, thanks to the digital lab that has been implemented. Using liquid monomer technology, Eye Mobile is able to make its own lenses. As such, (for most prescriptions) patients can obtain their glasses quickly, imagine that! Two weeks wait for completed glasses have become the exception and not the norm at Eye Mobile!”

We congratulate our friends at Eye Mobile and their ever expanding business!

What Free-Form Is

At Optical Dynamics, we use digital free-from molds to produce customized lenses with improved optics and enhanced visual clarity. As published in Eyecare Business, the following six points are key to understanding the free-form process.

  1. The main difference between digital and traditional surfacing is digital surfacing’s ability to produce more complex surfaces with extreme accuracy.
  2. Digital surfacing can be used to create simple single vision or complex progressive surfaces. The ability of the lens to provide visual comfort and performance is determined by the quality of the design.
  3. Digital surfacing is referred to as direct-to-surface, CNC and free-from. All refer to basically the same process.
  4. The most significant variable involves the process used to calculate the design. Digital surfacing processes require significantly more calibration and control compared to traditional surfacing.
  5. There are two inherent benefits common to nearly all digitally surfaced PALS: reduction of marginal astigmatism and reduction of “rounding errors”.
  6. Remember: all lenses that bend light will have aberrations and spherical surfaces create aberration. Its a matter of how those aberrations are managed that provides a unique benefit to the wearer.
