a glass eye

Answer 1

Adding on to the wonderful answer below. A glass eye is the only one that doesn't need to contain a lens as it is created purely for 'decoration' and not to enable someone to see better.

Answer 2

It's A. a glass eye does not contain a lens.

a jeweler's loop is a magnifier lens that a jeweler uses.

a floodlight has a lens and eyeglasses also have lens.
