What's the difference between focus and optometer?
Focus

(n.) A central point; a point of concentration.
(v. t.) To bring to a focus; to focalize; as, to focus a camera.

Optometer
Definition:
(n.) An instrument for measuring the distance of distinct vision, mainly for the selection of eveglasses.
Example Sentences:
