There are many kinds of lenses. Your degree is relatively low, so it is unnecessary to match such a good lens. In most cases, you will be killed. Resin lenses are also good. Traditional lenses will not break if they are not hit by a great force. Glass lenses have good light transmission, but they are too heavy. In fact, you can use the aspherical lens of 1.56, and you don't need to wear it at ordinary times. Wear it at night, because there is astigmatism, and objects will have ghosting at night. As for the lens around 600 you mentioned, I haven't seen what brand it is, and of course I won't tell you. As long as you can see clearly, don't bring it. Usually watch these electronic screens less.
