Not able to see; not visible or apparent; obstructed from view.

Unsighted → It is formed from "un-" (meaning not) and "sight" (from Old English "sīeht", meaning vision or the act of seeing) and the suffix "-ed" (indicating a past participle). The word "unsighted" means not having sight or vision, or being unable to see.
Think of 'not' ('un-') having 'vision' ('sight') — that's why unsighted means unable to see.
