Answer:

Compared to other materials, the use of sheet and plastic sunglasses frame on the surface is not see the difference. First of all, the plate frame is a memory function, if you buy the sunglasses mirror legs for you too tight or too loose, then you can adjust the mirror legs, straighten the bend is not a problem, but also inside and outside the bending Adjustment. If it is a plastic material sunglasses frame, a small adjustment does not work, it will automatically change back to the prototype, if a substantial adjustment - it will not change back to the prototype, because it has been broken ... Secondly, from the details, the frame of the frame to wear more comfortable, the basic will not appear discomfort. The plastic frame in addition to the overall structure is relatively stiff, is not conducive to the adjustment, the external paint may also be processed, there will be irritating smell. Finally, the frame of the frame will have steel (think of reinforced concrete, there are wood), durable. Plastic frame it, in addition to plastic or plastic, can be used to know how long days. So look at the appearance, you can not find the difference between these sunglasses.
