Finding the Right Blue Light Solution For Your Office

By Johnna Dukes, ABOC
Monday, March 21, 2016 10:11 AM Everywhere you look you are inundated with information about how harmful blue light is for your visual system and your body in general when it comes to disruption of sleep cycles. You probably understand blue light is harmful, but might not be sure which products will work best in your office. Which products do what they claim and what should you tell your patients about them? So, what’s a good Optician to do? What we always do, find solutions for our patients.

Talk Performance in Presenting AR

By Robert L. Bass, OD, FAAO
Monday, December 7, 2015 2:10 PM Increasing sales of lenses with anti-reflective (AR) treatment is a priority for my practice. AR lenses provide better vision to patients and relieves eye strain, and selling more eyewear with AR is a revenue-generator. Of the 250 patients we see on average each month, 31 percent, or 78 patients, get  AR on their eyeglasses. Sales of glasses with AR generate about $7,500 in additional optical revenues per month. We're working toward doubling our AR penetration.

And so we move forward, on to part three of my groundbreaking series on blue blocking lenses, a collection of thoughts and observations that will sure to become part of optical lore and studied by apprentice opticians years down the road...

Insert Blue Pun Here: An Overview of Blue Blocking Lenses

By Preston Fassell, BS
Wednesday, June 3, 2015 10:00 AM Dispensing with the niceties (haha, optical pun!) of a long-winded, winding and witty introduction, I’m just going to get right on to it. After all, we all know why we’re here: This is the Blue Blocker crucible, where lenses are ground down and only the truth remains.

AR Lenses

By Ari Siletz
Wednesday, January 14, 2015 11:00 AM This article is about how anti-reflection coating reduces reflections from eyeglass lenses. But before we go there let's ask a more fundamental question: Why does glass reflect in the first place, after all, isn't glass supposed to be transparent?

Anti-Reflective Coating...Are We Looking at This Wrong?

By Norm Kester, Quantum Innovations
Tuesday, July 23, 2013 2:00 PM When I am on a plane, in an airport or at a dinner and people ask me what I do, I respond by saying, "I bend light and count molecules for a living." This is a pretty grand statement and most times I am proud of the complex, medically beneficial science that I am in.

Is Your AR Coating Stressed Out?

By Norm Kester, Quantum Innovations
Wednesday, May 8, 2013 4:37 PM I have had many conversations through the years regarding Cracking and Crazing of AR coating, and what causes each. In this article, I want to discuss several of the things that lead to Cracking and Crazing in an effort to understand the relationship between the lens, the layers of the coating and the coating as a whole.

AR... No Better Time to Jump In

Sunday, September 16, 2012 11:00 PM In 1935, the first anti-reflective (AR) coating was invented at Carl Zeiss. These coatings significantly reduced annoying lens reflections while increasing light transmittance and visual clarity.

By Darryl Meister, ABOM, Carl Zeiss Vision
Sunday, September 16, 2012 10:58 PM Anti-reflective lenses usually have three or more thin layers of ceramic or metal oxide on each side of the lens. By varying the refractive index of each layer, reflections from one layer can be made to interact with reflections from the next layer.

AR Lens Technology

By Staff
Thursday, July 19, 2012 9:30 PM The basic concept for how anti-reflective coatings work is the optical interference model. Each coating layer in the AR stack combines with previous layers to cancel out a broad range of light waves by introducing opposite, or destructive, waves that are out of phase.

Lens Clarity: Anti-Reflective Lenses

By Staff
Monday, March 5, 2012 4:55 PM When it comes to providing the clearest vision to your patients, anti-reflective (AR) lenses are critical to providing your patients with optimal vision. Recommend AR lenses to all your patients because it is best for all patients.

Scratch and Anti-Reflective Lenses

By Miriam McGorrin
Tuesday, November 22, 2011 12:17 AM Coatings are applied to a variety of surfaces to increase abrasion and scratch resistance. Plastics can be used in many applications where bare substrate alone would not survive.

Hard Coating Systems

By Miriam McGorrin
Tuesday, November 22, 2011 12:00 AM Performance and versatility can be greatly improved by using them in combination with a primer. The combination of hardcoat and primer are often referred to as a hardcoating system.
