Shamir Coatings

Shamir Anti-Fog


A newly developed lens coating, Shamir Anti-Fog
prevents the rear lens surface from fogging up.
It does this by adsorbing the fog that accumulates on the lens.

Foggy moments

Anyone who wears glasses is likely to have experienced the discomfort of blocked vision when the rear surface of their lenses fog up, virtually blinding them. This can be uncomfortable, disturbing, or even dangerous.

It can happen when stepping out in the cold, or when entering an air-conditioned environment, and it's most likely to happen during strenuous activity when the body is giving off more heat, and humidity gets trapped behind the lens.


Formation of fog on lenses with various coatings: 



When does fog appear?

When humidity coming off the body gets trapped behind the lenses, and the lens temperature is lower than  that of the trapped humid air, then the rear surface of the lenses fog up.

Who benefits from Shamir Anti-Fog?

Shamir Anti-Fog is suitable for anyone who regularly experiences rear lens surface fogging. These will most likely be people engaged in:

- Sports, both indoors and outdoors

For additional lens protection, we recommend combining Shamir Anti-Fog with one of Shamir's advanced Glacier Plus™ coatings on the front surface of the lens.

Shamir Anti-Fog can be applied to clear, polarised, Transitions or pre-tinted lenses, and is suitable for any frame.


To keep lenses with Shamir Anti-Fog clean

- Cleaning the front and back lens surfaces separately is recommended.

- To remove dirt from the back surface, it is recommended to use a wet cloth and then dry it with a dry cloth.

- Do not clean with acetone.

Shamir Anti-Fog comes with a 12-month guarantee covering manufacturing defects.


Useful tip

When providing patients with their lenses, it should be emphasized that during extended periods of time under conditions of high humidity, the lens coating may reach its adsorption capacity and lenses may become covered with a thin layer of water or begin to fog. In such cases, simply wipe the lens with any available soft cloth (even your shirt), and normal fog adsorption will be restored.

* Shamir Anti-Fog meets the EN-166 European Standard - the requirement for the time in which lens clarity is maintained under controlled humid conditions
