Optifog, the best and most durable protection against lens fogging.

What is Fog?
How to explain foggy eyeglasses?
Fog is water vapor which is condensed into tiny droplets lying close to a surface and limiting considerably visibility.

Eyeglasses become foggy with temperature change, always from a cold to a hot environment.

Fog on lenses depends on different factors:

* The 
temperature difference between the two environments
Relative humidity in the hot environment entered by the wearer
Time of exposure allowing the lenses to adopt the surrounding temperature

Fog is a daily discomfort for eyeglasses wearers. This  always comes on eyeglasses from quick temperature variation in a humid environment.
Fog may happen at every moment of the day, in everyday life situations. 

1. Changing environment

Moving from cold to hot environment like getting out of an AC environment or coming in a heated place is always creating fog on wearers eyeglasses. 
Getting in a bus                 Getting out of a car

2. Indoor activities

        Driking hot beverages       Eating hot food              
Boiling a pot of water     Opening the dishwasher

3. Outdoor activities     

Fog happens on lenses when playing sports such as running, cycling, playing tennis, skiing…

Running                         Cycling
Playing tennis                     Skiing      
A real discomfort during leisure activities such as driving, biking, playing paintball...                                                                       
   Paintball                      Driving / Racing 

 4. At work

Work environment where precision and safety are a priority for the wearers, where wearing a mask or goggles is needed, where changing environment is constant.


Essilor has developed Optifoga breakthrough lens with an exclusive anti-fog property which is the result of intensive Essilor Research & Development work.
Optifog, the best and most durable protection against lens fogging. 

The Optifog lens is activated by the Optifog Activator by simply adding a drop of this concentrate to each side of the Optifog lens.
By gently wiping with a microfiber cloth to make sure to coat the entire surface, eyeglass wearers will find that their vision becomes perfectly fog-free up to one week.

Optifog can work for anyone experiencing problems with fog on their eyeglasses, and is suitable for eyeglasses that correct all types of vision problems.
The result:  No distortion and no loss of contrast


Truly long lasting fog free vision
The many tiny water droplets caused by fog perfectly spread on the lens surface, creating a uniform film of water, invisible to the wearer. 

Wearers Tests
Essilor is using Wearers Tests to assess the efficiency of its new lenses. It is important to know whether a specific product improvement supported by instrumental tests is actually perceived by the eyeglass wearer and whether it leads to a better overall appreciation of the product.
Eyeglass wearers tested Optifog lenses in everyday life situations, where fog can appear on their lenses. 
Wearers Tests results* confirm Optifog performances: 
  • 79% of wearers are satisfied with its fog repellence efficiency**

  • 81% of wearers are satisfied with its efficiency one week after activation**

  • 77% of wearers are satisfied with its ease of cleaning **

  • 87% of wearers are satisfied with its transparency after cleaning**

    * Wearers Tests conducted by a third independent party (France 2011) - Base : all weaers included ( n=100)
    ** Average assessment on fog repellence efficiency at 0,8 and 20 seconds

Is Optifog only for hot and humid countries or cold countries?
No, lens wearers can experience fog on their lenses in all regions even in temperate climate. The frequency of fog may vary but it also depends on individual activities (at work, leisure, everyday life…).

Is Optifog Activator dangerous for one’s eyes?
When applied on the lens, there is absolutely no danger. If a drop does come in contact with eyes, just rinse with water.

Is Optifog the first anti-fog lens? 

Optifog is the first premium ophthalmic lens to bring a perfect and durable protection against fog, associated with maximum protection against other vision enemies such as scratches or glare.

What is Optifog system benefit vs antifog liquids?

Other systems are sold on the market but with less anti-fog efficiency and less everyday clarity of vision. Optifog also provides a more durable solution than its competitors: the anti-fog coating of Optifog durably retains the Optifog Activator for up to one week, under normal conditions.

Moreover anti-fog liquids sold on the market have very variable quality. Even the most efficient of them can bring only anti-fog properties on standard lenses from a couple of hours up to one day. And some fog can remain on the lens.

May I activate Optifog lenses with another anti-fog liquid?
 Optifog maximum anti-fog efficiency depends on the perfect interaction between the lens and the Optifog Activator. The lens has been specifically designed to protect against fog. The Optifog Top Layer has been specifically developed to bring maximum efficiency with Optifog Activator. When other anti-fog liquid are used performances are much lower and can be disappointing for wearers.

Is Optifog a patented innovation? 
Optifog is a technology covered by an international patent application.

E-mail Rx-Lens ordering application for the retail optical shops!!! with source code.

Today several sophisticated lens ordering programs are available in the market. Most of them are belongs to the lens suppliers. But still there are huge number of optical retailers are ordering the lenses by e-mail.

  • The major Drawback of mail orders is the high ratio of typing error.
  • There is no validation of cross checking
  • Always a need of formatting the text or fonts.
  • No option for selecting lens types, always need to be typed.

To avoid these difficulties, I have developed an application which will help you to make lens orders without making a least error percentage. You can use this application to send a lens order to any company via email. This program is completely developed in Visual Basic 6. I am uploading the source code of this program so that developers can modify this according to the individual need. Hope I covered almost possibilities to avoid less typing and mistakes. There is a separate database for lens type. (lensdata.mdb), You can add your lens types to this file. I have already put almost lens types from Zeiss. This databese will give you full freedom to input thousands of lens types.

The order will be sending to a pre-defined e mail id. You can define a CC field to get one copy to your id for the future reference.

I have used gmail settings to send the email. (all order will be sending from, you can change it if you need a different id) So there is no e-mail sending program needed to send an order.

The Magic of ic! berlin

Ralph Anderl - The founder
Proving that German craftsmanship is amongst the best in the world, IC! Berlin and PlastIC! Berlin Eyewear feather-light screw-less and flexible frames combines urban elegance with uncompromising strength. This collection is hand crafted from 0.5 millimeter thick stainless steel while featuring its patented spring-hinge-clasp-system, preventing each frame from losing its shape while providing perfectly designed eyewear that rarely has need for adjustments.These creations amaze everyone who has the opportunity to wear them. Designers Phillip, Ralph and Harald have elevated fashion eyewear and frame technology to a new level. This is one company not afraid to be different and does not waiver from their concept. With inspiration from art and architecture, the designers of IC! Berlin and PlastIC! Berlin frames have captured the ideal concept of eyewear design combining minimal and bold.IC! Berlin and PlastIC! Berlin looks great everyone, so go ahead pick a pair that's right for you.

Ic! Berlin is an cool eyewear concept developed by Philipp Haffmans and Harald Gottschling in Berlin in 1997, before they founded their new brand MYKITA in 2003. 
The company’s mainstay is sheetmetal glasses, priding itself in designing and producing them without screws, soldering or welding. The screwless system allows users to separate the temples from the front frame, and change the lenses by hand with a few twists and turns.
ic! berlin temples are uniquely designed to use no screws, however, this sometimes leaves people confused as to what to do when the temples come off. Here's a very detailed video that shows how to take the temples off and on all by yourself. Or, if this just doesn't appeal to you, bring them on in to us & we'll fix them in no time flat!

ic! berlin hand makes all their glasses out of stainless steel sheet metal. Here is a great video to get an idea of all the handiwork that goes into these special frames
