When were scratch resistant lenses invented?
Nearly every company who makes glasses today uses the scratch resistant coating! This makes our lives better since we can actually save the hassle and we don’t have to take much care at all to make sure our glasses don’t scratch! This was discovered in the Ames Research Center in the year of 1989.
Where did scratch resistant lenses come from?
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.
Why did NASA use scratch resistant lenses?
Scratch Resistant Lenses were used in space in to keep space equipment from getting scratches, especially helmet visors. These space helmets visors were developed so that when astronauts were exploring on the moon, they could see what they were doing and not have their vision affected by its environment.
Are scratch resistant lenses really scratch resistant?
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.
Why are scratch resistant lenses important?
Scratch-Resistant Lenses This can minimize the damage to your lenses if you accidentally drop them, or clean them with the wrong type of material. When eyeglass lenses are scratched, they become less clear and are more likely to cause eye fatigue.
Do I really need scratch-resistant lenses?
SCRATCH-RESISTANT This coating will make your glasses less vulnerable to scratching if you happen to drop them or clean them with an abrasive cloth. “Many glasses wouldn’t last a day without this,” Vitale says. “Polycarbonate and high-index lenses are very soft.”
How scratch-resistant are glasses?
No eyeglass lenses — not even glass lenses — are 100% scratch-proof. However, lenses that are treated front and back with a clear, scratch-resistant coating have a much harder surface that is more resistant to scratching, whether from dropping your glasses on the floor or occasionally cleaning them with a paper towel.
Are scratch resistant lenses worth it?
SCRATCH-RESISTANT This coating will make your glasses less vulnerable to scratching if you happen to drop them or clean them with an abrasive cloth. “Many glasses wouldn’t last a day without this,” Vitale says.
Do I need anti-scratch coating on polycarbonate lenses?
AR coating is highly recommended for all eyeglass lenses, but particularly for polycarbonate and high-index lenses, which reflect more light than regular glass or plastic lenses if anti-reflective coating is not applied.
Is it worth getting anti-scratch on glasses?
These lens coatings will upgrade the way your lenses perform and the way your eyes respond to them. So, if you’re still wondering whether or not the anti-glare and anti-scratch coatings are worth the small, additional price you would pay to have them added to your new glasses, the answer is yes – absolutely.
How long does scratch resistant coating last?
One lens coating that can increase the life of your lenses is scratch resistant coatings. Use these if you tend to handle your glasses roughly or use them in rough environments. According to Dr. Moos, lens enhancements and coatings can last anywhere from a year to about two years.
Where did the idea of scratch resistant lenses come from?
Some of the earliest research into effective scratch-resistant coatings for prescription and sunglass lenses drew from work done at Ames Research Center on coatings for astronaut helmet visors and plastic membranes used in water purification systems.
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.
Are there any eyeglasses that are scratch resistant?
But surprisingly, after you catch yourself treating them like a dirty napkin for the tenth time, you notice that the lenses still give you a sharp view and are miraculously free of major scratches. Chalk your good fortune up to one of the modern marvels of life in the 21st century:scratch-resistant lenses.
When did Essilor start using scratch resistant lenses?
The brand Foster Grant, who had been searching for a scratch-resistant coating for years, licensed the technology in 1983 and soon the know-how spread throughout the industry.
