Can someone explain this to me?

Crizal Alizé with Clear Guard has incorporated the same technology used in plasma televisions to add an integrated anti-particulate layer into the AR process.

I just looked up how plasma tvs work and I don't see the connection between the two.

[chip anderson]

I think both are vaccuum chambers with Ions blasting through same. In the case of lenses to remove debris and impart a charge. In the case of plasma TV's to activate the color whatevers on the front of the screen.
Besides they both contain the catch word "Plasma" that like saying technology instead of mechanics.
The buzz has gone out of the term "Anti Reflective" so they need a new word.

Would it be anything like muffler bearings? A mechanic once said I would get better performance from my vehicle and he was the only person that sold them:shiner:.

In the Essilor Clear Guard Formula they incorporate an ITO (indium Tin Oxide) layer which is an anti-static layer to allow the A/R stack to repel dirt, dust and small particulates which can cause scratching during cleaning of the lens surface. Most tv's and computer screen using the same coating layer

......When Herb Werthiem OD (founder of BPI) coined the term "energized molecules" which made his tints superior. An employee of mine who has since founded his own highly sucessful optical shop, pointed this out to me. I called Dr Werthiem and asked him exactly what that meant.(all molecules are energized) He just started laughing........all the way to the bank. The one thing I got out of my marketing minor was to sell the sizzle not the steak! You have to love the creativity involved.

PS I also liked Chip's response! Sounded good to me! ;)

Somebody help me out here.

Fact is Essilor IS the champ of marketing. I have spent a long career competing with them. Never stopped to realize how much $$$ they have put into ALL our pockets, including their competition.

I got the new long-life muffler bearings on my new car, runs like a champ! I really don't understand how the bearings don't get all beat up with all the heat and water vapor though.

So they are the best at finding what the customer wants and delivering it to them?

Once again Jim, I'm just trying to ask a question. I'm still an Optician at heart and increasing my knowledge base is important to me.

They are the best at telling the customer what he/she wants and imposing it upon them.

I really don't know the answer to that question. I will say that regardless of what you wind up fitting, you will find more customers that know what a Varilux is than you will find knowing what a progressive is. They lead the US progressive movement in the 70s by training the lens fitters and manufacturers in proper fitting and manufacturing. (Without this the progressive product was a miserable failure.) They maintain a close relationship with retailers by providing all kinds of training that is of mutual benefit. I'd guess they spend more money on advertising than all their competitors combined. Advertising that is responsible increasing all of our business. Because of all these smart moves, they have been responsible for being the largest company with the greatest market share.

Well that is not marketing then

i-coat offers versions of AR comparable in design and quality to the Crizal. We offer it and have no complaints from customers. Look for Vivix and Vivix Stainless. Cost's less than Crizal too!

[Judy Canty]

All this is really wonderful, but no one's explained the relationship between my plasma tv and my CAw/CG coated lenses.

Do you remember SEVERAL years ago, when Ford wanted to introduce it's version of the mini-van? The commercials on TV showed the Space Shuttle after landing back on Earth, sitting on the runway. A close-up of the nose was then "masked" by the Aerostar minivan pulling up. The idea: the same technology that's used in the shuttle is in your new van! For naive people, that must surely by the best thing in world! The same applies to your question. Plasma TVs are the most-fabulous-best-greatest thing that has EVER been on Earth, and now you can wear the same thing on your face. For the naive population, anyway.

For the naive population, anyway.
Man, they sure are.

ITO (indium Tin Oxide) layer which is an anti-static layer to allow the A/R stack to repel dirt,


Indium tin oxide's main feature is the combination of electrical conductivity (http://en.wikipedia.org/wiki/Electrical_conductivity) and optical transparency (http://en.wikipedia.org/wiki/Optical_transparency). However, a compromise has to be reached during film deposition, as high concentration of charge carriers (http://en.wikipedia.org/wiki/Charge_carrier) will increase the material's conductivity, but decrease its transparency

ITO is mainly used to make transparent conductive coatings for liquid crystal displays (http://en.wikipedia.org/wiki/Liquid_crystal_display), flat panel displays (http://en.wikipedia.org/wiki/Flat_panel_display), plasma displays (http://en.wikipedia.org/wiki/Plasma_display), touch panels (http://en.wikipedia.org/wiki/Touch_panel), electronic ink (http://en.wikipedia.org/wiki/Electronic_paper) applications, organic light-emitting diodes (http://en.wikipedia.org/wiki/Organic_light-emitting_diode), and solar cells (http://en.wikipedia.org/wiki/Solar_cell), and antistatic coatings (http://en.wikipedia.org/wiki/Antistatic_coating) and EMI (http://en.wikipedia.org/wiki/Electromagnetic_interference) shieldings.
ITO is also used for various optical coatings (http://en.wikipedia.org/wiki/Optical_coating), most notably infrared (http://en.wikipedia.org/wiki/Infrared)-reflecting coatings (hot mirrors (http://en.wikipedia.org/wiki/Hot_mirror)) for architectural, automotive, and sodium vapor lamp (http://en.wikipedia.org/wiki/Sodium_vapor_lamp) glasses. Other uses include gas sensors (http://en.wikipedia.org/w/index.php?title=Gas_sensor&action=edit), antireflection coatings (http://en.wikipedia.org/wiki/Antireflection_coating), and Bragg reflectors (http://en.wikipedia.org/wiki/Bragg_reflector) for VCSEL (http://en.wikipedia.org/wiki/VCSEL) lasers.
ITO thin film strain gauges (http://en.wikipedia.org/wiki/Strain_gauge) can operate at temperatures up to 1400 °C and can be used in harsh environments, eg. gas turbines (http://en.wikipedia.org/wiki/Gas_turbine), jet engines (http://en.wikipedia.org/wiki/Jet_engine), and rocket engines (http://en.wikipedia.org/wiki/Rocket_engine) [1] (http://digitalcommons.uri.edu/dissertations/AAI3025561/)

See at: http://en.wikipedia.org/wiki/Indium_tin_oxide


PS: above list of applications shows that the optical is not the only one using these products.
