The Composition and Structure of Sports Glasses
Introduction to Sports Glasses
Sports glasses refer to safety protective glasses worn during exercise, usually equipped with advanced equipment that is safe (PC lenses), protective (TR-90 frame, soft and elastic), comfortable (non slip nose pads and foot covers), and aesthetically pleasing (paired with sports and leisure clothing).
Sports glasses structure
1. Lenses
1) PC lenses, also known as space lenses, are non shattering and non cracking lenses with 100% safety. It is currently the lightest and thinnest lens in the world, 57% lighter than glass lenses, 37% lighter than resin lenses, and 26% thinner. It is currently the most impact resistant lens in the world, and its material is first used in space shuttle observation windows and bulletproof glass. Its impact resistance is 60 times that of glass lenses, 10 times that of ordinary safety resin lenses, and 100% UV resistant (UV400).
2) Magnesium alloy lenses are lightweight, 2/5 of titanium and 2/3 of aluminum, with a machining accuracy error of only 0.02mm. They have bright colors and are not easy to fade. They can be added with different colors, making them environmentally friendly products. Benefit: It has a stylish and lightweight feel when worn.
3) Polarizing lenses use the principle of polarization (i.e. the principle of louvers) and can filter out stray light. In addition to filtering out harmful ultraviolet rays 100%, it can also automatically adjust and block strong reflected light that ordinary sports glasses cannot block. It adjusts all the projected light to be in the same direction, eliminating glaring reflected and scattered light, making the eyes see things clearer and have a better line of sight in sunlight. Suitable for outdoor activities such as picnics, driving, fishing, and mountain climbing.
2. Mirror frame
The TR-90 frame is made of super tough resin material, which is smooth, flexible, and lightweight, making it comfortable to wear. The characteristic is high temperature resistance, can withstand 350 degrees Celsius in an instant, is not easy to melt and burn, has an impact resistance of more than twice that of cellulose acetate plastic (CA), has memory function, a deformation resistance index of 620KG/CM2, and is 30% lighter in weight than CA.
Selection of Sports Glasses
1. Glasses have different functions
Due to the diverse types of outdoor sports, including extreme cycling, outdoor mountaineering, jogging, skiing, golf, camping, and other sports, the functional requirements of sports glasses vary for different sports.
1) Windproof mirror
Suitable for long-term sports enthusiasts in the outside world, especially in areas with strong sandstorms.
2) Myopia sports glasses
To meet the needs of myopic sports enthusiasts, the emergence of myopic sports glasses has brought them good news. The functions of myopia sports glasses not only include the performance of general myopia glasses, but also use PC material with an impact resistant surface, so that myopic friends can also enjoy the fun brought by sports.
3.) Polarized sports glasses
Also, for exercise that involves long-term exposure to strong and prolonged sunlight, it is necessary to purchase polarized sports glasses. For mountaineering enthusiasts, snow on high mountains can easily damage their eyes. In terms of ultraviolet radiation, the reflected light from snow at a height of 10000 feet exceeds that of the seaside by more than 50. The retina of the naked eye is easily damaged, causing great pain. It is called snow blindness. Sunglasses can reduce this damage, but do not be affected by cloudy weather
