Ask about the vision requirements for maintenance work?

There is no problem with myopia, and it is generally to correct vision. The requirement of vision maintenance is that there should be no color blindness or color weakness, because there are many things that are distinguished by color at work. There are many kinds of work in the locomotive depot: operation (driver), maintenance, equipment ... Except for operation, that is, the driver has strict requirements for vision, other workshops have low requirements for vision.
