The Anti-Fog Effect

Sunglasses are worn by millions of us everyday when we are walking out our front door. There are many benefits to these dark shades including, help us drive easier, keep our eyes healthy from the strong sun rays and of course being used as a fashion accessory.

The sun, though isn’t the only natural deterrent that can effect our vision in the outside world. With temperature changes, moisture and humidity can also have role in the way we see. If there is a lot of moisture in the air, our sunglasses can fog up, making it also very difficult to see. Sometimes harder then from the sun’s rays.

Welcome to the world of anti-fog agents! Anti-fog agents, also known as anti-fogging agents and treatments, are chemicals that prevent the condensation of water in the form of small droplets on a surface which resemble fog. They were first developed by NASA in 1966 during Project Gemini, and are now often used on transparent glass or plastic surfaces used in optical applications.
