Are the lenses of the oval frame the same?

The same is true for oval-frame lenses.

When an optical shop matches glasses, the lenses are polished according to the frames, so the frames and lenses are the same. Oval glasses have little requirement for face shape. In addition, although oval glasses are versatile, the nearsighted frames are not suitable for being too big, otherwise the weight will be heavier and the nose will be a little pressed.

A lens is a piece of glass or other transparent material with one or more curved surfaces, through which things look clear, big or small. Usually used in glasses, cameras, telescopes, etc. Ordinary lenses are divided into resin lenses, special lenses, space lenses, glass lenses and pvc lenses.
