Which is better, silica gel or air cushion nose pad?

Although on the surface, the air cushion nose pad is more elastic and has less pressure, in the actual use process, the pressure on the bridge of the nose is not much different from that of the ordinary silicone nose pad. Moreover, due to the hollow design of the air cushion nose pad, the front material is easy to be damaged due to insufficient thickness. If you don't pay attention, the metal nose pad will directly act on the bridge of the nose, which is not safe. In addition, the hollow design will lead to dirt entering, which is easy to get dirty and affects the image.
