Plural of eyesight; the ability to see or instances of seeing something.
From Old English 'eage' (eye) + 'sight' (the ability to see). Compound formed in English by combining the organ of vision with the faculty of seeing, dating back to Middle English.
Eyesight is one of the few senses we have a specific compound word for—we don't usually say 'earsound' or 'nosenose,' which shows how crucial vision was to our ancestors' survival and language development.
