It is known to all that workers engaging in electro-welding would gain potential harm to their eyes, which originates from the ultraviolet radiation given out during the welding process. Firstly, let's learn harm to eyes from the electric welding's arc light. Usually, the temperature of the arc light would reach to 30004000, and at the same time, the light offend the eyes very much. Besides, a great amount of invisible light, like infrared rays and ultraviolet radiations would be produced. All of them are pretty bad for eye health, especially the UV. If not protected well enough, eyes would probably suffer from blepharitis, conjunctivitis and even cataracts and retinal burn.
Therefore, electric welders would use a specially made face shield to protect themselves. However, those face shields are usually rather heavy and ponderous, which constitutes an inconvenience for the workers. What's more, at present lenses of those face shields are of dark colors with low transparency, which poses as an obstacle for the users to see the target objects clearly.
Fortunately, in practice, it is found that transitions glasses would serve as a good protection for the eyes. Then how do transitions glasses work to protect eyes? For transitions glasses are able to change their colors of lenses when encountering ultraviolet radiations, when in the strong light, the lenses get darker, and could alternatively absorb ultraviolet radiations and infrared rays. In a matched pair experiment, we observe that those who wear transitions glasses have less possibilities to suffer from eye diseases, and the arc light appear no longer to offend to eyes.
Into the bargain, if you choose wraparound transitions glasses, the fume generated by arc welding is also impossible to fly into eyes. The experiment also shows that welding workers would like to wear transitions glasses very much, because they find they are light, convenient, aesthetic and effective, and more importantly transitions glasses reduces possibilities for them to suffer from kinds of eye diseases. The fact is that, if the workers would wear transitions glasses and face shields at the same time, their eyes would better be protected. Therefore, they are suggested to use the two simultaneously when they engage in some simple works.
At present, there are transitions glasses of different styles, for welding workers, those with wide frames, wraparound and easy to get fixed around the head should be the best choices.
