Sunglasses allow better vision in bright daylight, and may protect one's eyes against damage from high levels of ultraviolet light. Typical sunglasses are darkened for protection against bright light or glare; some specialized glasses are clear in dark or indoor conditions, but turn into sunglasses when in bright light. Most sunglasses do not have corrective power in the lenses; however, special prescription sunglasses can be ordered. Specialized glasses may be used for viewing specific visual information (such as stereoscopy) or 3D glasses for viewing three-dimensional movies. Sometimes glasses with no corrective power in the lenses are worn simply for aesthetic or fashion purposes. Even with glasses used for vision correction, a wide range of designs are available for fashion purposes, using plastic, wire, and other materials.
Every car pitches if it goes into a corner. The pitch represents the number of degrees the auto tilts in the event it turns. The higher the pitch, the more the automobile is regarded as to roll. In general, roll just isn't good. It is uncomfortable and puts stress on from your tires to steering linkage and also the frame of the automobile. Over time, this may all cause problems.
