Vzorec užití:
optic [noun]
Častá chyba:
Learners often confuse "optic" with "optical." "Optic" is most common in medical or biological phrases like "optic nerve," while "optical" is more general and used for devices or physics, like "optical lens" or "optical cable." Learners may also try to use "optic" on its own to mean eyesight (e.g., *"My optic is bad"*), but natural English uses "eyesight" or "vision" instead.
Synonyma
ocular (More formal and technical; used mainly in medical or scientific contexts.)
Antonyma
nonvisual (Describes things not related to sight or vision.)

sighting device for aiming
A device you look through, like a scope or sight, to help you aim a gun or see better with a tool.
Vzorec užití:
mount an optic on [something]
Častá chyba:
Learners may think "optic" as a noun means the eyeball itself in modern everyday English, but that use is rare and sounds old-fashioned. In current informal use, especially in gaming and shooting contexts, "an optic" usually means a scope or similar sighting device.
Synonyma
scope (More common everyday term; sounds less technical and is widely understood, especially for rifle sights.)
Antonyma
iron sights (Refers to basic metal sights on a gun, used without any optical device; contrasts with using an optic.)
