说明书全文 | 1. Field of the Invention The present invention relates to an improvement on a lens structure of safety glasses, more particularly one, which has a light reflecting portion on an upper border thereof for producing warning effect. 2. Brief Description of the Prior Art Different types of eyeglasses are available, which serve respective purposes. For instance, safety glasses are to be used to protect eyes from injuries by people who participate in sports and who are working, which injuries are usually caused by hitting of objects such as bats, balls, and liquid and small bits of melted metal at workplaces. According to a research, 90 percent of all sport and work-related eye injuries can be prevented if safety glasses are worn. Common currently existing safety glasses consist of a hard lens part, a rim, a soft protecting part joined to a border of the rim, and an elastic, which is connected to two ends of the protecting part at two ends thereof; thus, the safety glasses can be firmly positioned around the wearer's head with the soft protecting part closely touching the face. Referring to However, the reflecting layer is prone to wear and erode owing to rubbing and perspiration, and in turn will fall off after it has been used for a long length of time. Consequently, the harmful substance in the reflecting layer will stick to people's skin, and cause harm to the health. Therefore, it is a main object of the present invention to provide an improvement on a lens structure of safety glasses to overcome the above-mentioned problems. The lens structure of the present invention consists of a lens part, and a warning sticker. The lens part consists of a main body, and a rim formed on a border of the main body, which rim has a strip-shaped recess on an upper portion, extending along an upper border thereof. The warning sticker is nontoxic, and contains no harmful substance, and it is stuck on the strip-shaped recess of the rim therefore the warning sticker won't cause damage to health or stick out from the rim. Consequently, it is impossible for the warning sticker to be subjected to pulling force and fall off. The present invention will be better understood by referring to the accompanying drawings, wherein: Referring to The warning sticker 2 is nontoxic, and contains no harmful substance therefore it won't cause damage to health even if people and it are touching for a long length of time. Furthermore, the warning sticker 2 can reflect light, and is luminous. Referring to Referring to From the above description, it can be seen that the present invention has the following advantages: 1. The warning sticker of the present invention is nontoxic, and contains no harmful substance therefore it won't cause damage to the health even if people and it are touching for a long length of time. 2. The warning sticker is stuck on the strip-shaped recess on the upper portion of the rim therefore it won't stick out from the rim, and it's not possible for the warning sticker to be subjected to pulling force and fall off. |
