When did NASA make scratch-resistant lenses?
In 1983, Foster-Grant obtained a license from NASA for the scratch-resistant coating technology. The company combined its own technology with NASA’s and produced a superior lens.
Was the scratch-resistant lenses originally proposed for a mission?
Scratch Resistant Lenses weren’t proposed for a specific mission, but they were used in almost all of them.
What were scratch-resistant lenses used for in space?
Scratch-resistant lenses Because space environments contain dirt and particles that can damage astronauts´ helmet visors, NASA developed a process to create scratch-resistant lenses. The optical industry quickly seized on it to make eyeglasses ten times more scratch-resistant than before.
How did NASA make scratch-resistant lenses?
The DiamondHard® technology involves coating the lenses with a film of diamond-like carbon (DLC) that not only provides scratch-protection but additionally reduces surface friction, so that the lenses shed water more easily to reduce spotting.
Did NASA invent sunglasses?
NASA researchers picked up on the latter fact and used it to humans’ advantage. Their work ultimately led to the development of sunglasses that protect against eye damage by blocking out the most harmful wavelengths of solar radiation.
Are there scratch-resistant glasses?
There’s no such thing as scratch “proof” lenses. (Even glass lenses can be scratched!) Scratches, while not likely to affect your lens performance, are an annoyance that can interfere with clear vision.
Are there scratch resistant glasses?
What glasses dont scratch?
Polycarbonate and Trivex lenses are more impact-resistant than glass and plastic lenses, and both usually have a built-in scratch-resistant coating. This coating also can make their surface nearly as hard as glass.
Are scratch resistant lenses really scratch resistant?
How does scratch resistant work?
An anti-scratch coating, also known as a scratch-resistant coating, is a clear lens coating that reduces the appearance of hairline scratches, thus preventing minor scratches that can happen easily and impair vision.
How did NASA come up with scratch resistant lenses?
NASA’s Dr. Ted Wydeven of the Ames Research Center generated the technological seeds for the first scratch-resistant plastic lenses while working on a spacecraft water purification system. To alter a membrane in the purification process, Dr. Wydeven coated a filter with a thin plastic film using an electric discharge of an organic vapor.
How did Foster Grant come up with scratch resistant lenses?
Foster-Grant invested over 10 years of research trying to find a coating for lenses that could give glass-like scratch-resistance while keeping all the benefits of plastic. In 1983, Foster-Grant obtained a license from NASA for the scratch-resistant coating technology.
Why do lens need to be scratch resistant?
Scratch Resistant or Scratch Proof Lenses have anti-scratch coating applied to the lenses. It helps to prevent minor scratches that can easily happen to a regular lens. These minor scratches can damage the surface of the lens and impair vision.
Are there any sunglasses that are scratch resistant?
The company combined its own technology with NASA’s and produced a superior lens. Their scratch-resistant lenses lasted, with normal wear, ten times longer than the most widely used plastic optical lenses, surpassing even glass. Today, the majority of sunglasses, corrective, and safety lenses sold in the United States are made of plastic.
