Laser Safety Glasses

Lasers perform many amazing tasks in today's world. From replacing scalpels in surgeries to reading the information on a DVD so that we can watch movies, lasers affect our daily lives in more ways than we realize. However, with that widespread power also comes a bit of danger. Laser beams can damage skin and eyes when the proper safety precautions are not taken. To the average American, this might not mean much, but millions of people in the fields of medicine, science, research, and education should be well aware of laser safety procedures.

The easiest and most effective way of achieving laser safety is to always wear laser safety glasses when working around lasers. In fact, laser they are so easy to use, that they are also very easy to not use. It would be logical to assume that people who work around lasers every day would be very in tune to the importance of wearing laser safety glasses. However, it seems that the opposite is true. People who spend almost every day working around lasers get used to them, the idea of danger fades, and the fact your wearing them gets forgotten.

Since the inception of the laser beam in 1960, laser safety glasses quickly joined a long line of protective eyewear. People had been using protective eyewear for at least a hundred years. Anyone working in carpentry, welding, construction, or medicine already knew that protective eyewear kept their eyes safe from splatters and debris. However, they had to offer protection from radiation, which is a different beast altogether.

Laser safety glasses are manufactured with an average polycarbonate lens. The difference is that as the lenses are molded, chemicals like lead are injected into the mold. Such chemicals equip them with the required amount of wavelength filtration. The laser safety glasses will block certain strengths of laser light depending on their optical density. For example, ones with a high optical density will block a stronger laser.

Radiation accumulates in the body over a lifetime. That means that when you flew on a plane when you were five years old, the radiation from that trip is still inside you. Every time you have a dental x-ray taken, small amounts of radiation enter your body and never ever leave. Usually we come in contact with very, very small amounts of radiation which means we don't need laser safety glasses for these occurrences. However, people who work with lasers risk higher amounts of radiation, and they offer much protection.
