There used to be a kind of glasses with round lenses and black lenses. What kind of glasses are they called?

Glasses frames are optional. Many types of lenses are polished according to the types of frames.

sunglasses (also called sunglasses) are usually used for black lenses.

It feels like an old style. . -The exact point is sunglasses.

The original name is an earlier model.

I know what LZ is trying to say. Do you need a picture or something? Frog mirror = . = the answer is added, um, a big round mirror and the lenses are black. I think it's antique glasses. Compare the pictures.

Although the frog glasses are also big, they don't seem to be so round.

Compare the glasses of the Republic of China. It should be what LZ is looking for.

You can Google the antique glasses and choose the pictures.

See if it looks like that.
