about protective goggles

June 16th, 2015

Protective goggles are form of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes. They are used in chemistry laboratories and in woodworking. They are often used in snow sports as well, in cycling and in swimming. Goggles are often worn when using power tools such as drills or chainsaws to prevent flying particles from damaging the eyes. Many types of goggles are available as prescription goggles for those with vision problems, such as driving goggles, swimming goggles, ski goggles and so on. Take swimming goggles for example, it must be watertight to prevent water, such as salt water when swimming in the ocean or chlorinated water when swimming in a pool, from irritating the eyes or blurring vision. Allows swimmers to see clearly underwater. They will not be usable more than a few feet underwater, because the water pressure will press them tightly against the face.

The history of swimming goggles dates back at least to the 14th Century, when writers described Persian pearl divers using goggles with windows made of the polished layer of tortoise shells. That these goggles were possibly imported to Mediterranean countries can be deduced from the 16th Century illustration of Venetian coral divers using goggles. Goggles mysteriously disappeared from use, possibly because enslaved American Indian and African divers, who did most of the world’s commercial diving from the 16th Century onward, did not use goggles. Polynesian skin divers were known to use bamboo or goggles carved of wood. Originally, these wooden goggles had no lenses, but trapped air when the face was down, forming an air bubble over the eye that enabled the divers to see clearly when submerged. With the introduction of glass, the Polynesians added lenses.

If you are a novice, choosing the best swimming goggles for your needs can be a frustrating experience if you do not know what to look for at the sports store. It is advisable that you try on the swim goggles you are interested in, ideally the exact pair that you’ll be buying. Nothing is more frustrating than having bought a new pair of goggles that is uncomfortable or useless because it leaks. Now push the lenses some more against the eye sockets, then release them. The goggles should stick on your face a few seconds thanks to the suction, even if the straps are off. If this isn’t the case and the swim goggles fall off, they will leak water and be useless. If the goggles pass the first two tests, put the straps on and see if the goggles are still comfortable. Check if the lenses don’t suck too much on the eyes or that the straps must not be tightened too fast.
