A lens is a curved piece of glass or plastic that focuses or changes the direction of light. Lenses are used in cameras, glasses, and microscopes.
Usage & Nuances
Used for both corrective (glasses) and optical devices (camera, microscope). In photography, 'lens' refers to the detachable part you put on a camera; 'contact lens' is for eyes. Do not confuse with 'lens' as a metaphor (e.g., 'through the lens of experience').
