A pair of glasses with changeable lenses is revealed. A right frame and a left frame are communicated by a channel disposed on a bridge of an eyeglass frame. The eyeglass frame is divided into an upper part and a lower part by the channel, each of which is arranged with a magnetic part. The lenses are positioned by the magnetic parts attracted each other to close the channel. Or the two magnetic parts are pulled and separated to open the channel so that the lenses are able to be replaced. Therefore the lenses can be disassembled and assembled easily.
