Present It seems not many people wear eyeglasses anymore. Laser Eye Correction Surgery and contact lenses have become in more of a popular choice than eyeglasses. It seems now people wear glasses to protect there eyes. Sunglasses are glasses that are tinted some to help block the UV-Rays from the sun going directly into your eyes and hurting them. Sunglasses reduce the glare and therefore, making you able to see your surroundings better. Sunglasses that patrol officers wear make them able to see a speeding car go by easily. One problem with sunglasses are that some of the sunglass makers make them very poorly. Welders wear glasses with a darker tint than sunglasses to help with the rays of welding flames. The tint of the glass depends on the job. Welding produces hot metal which makes alot of infrared radiation. Arc welding produces large amounts of ultraviolet light. For that reason, the absorption of welding glasses isn't limited to visible light, but is carefully extended into the infrared (unlike sunglasses) and ultraviolet. Also, some astronomers sometimes use a shade 14 welding glass to view the sun with the naked eye. Alot of construction workers wear safety glasses to help protect them from flying particles. This helps reduce an injury to the eye. Avators and car racers wear goggles in order to protect their eyes from particles in the wind and the wind itself. When a car racer is going fast, alot of particles could be floating in the air and if that racer does not have the goggles on, he could be blinded and cause injury. Divers wear watertight goggles to stop water coming in onto their eyes during a dive. This helps the diver because the diver is able to see at normal vision (unless its dark) and nothing can damage their eyes.
