Tools for vision
Optical devices are instruments that manipulate light to extend or enhance vision.
The category includes eyeglasses, microscopes, telescopes, cameras, and projectors—anything that uses lenses, mirrors, or prisms to focus, magnify, or redirect light.
The optometrist's office was filled with optical devices for testing vision.
