There’s a correlation between eyesight and intelligence (in species, not individuals) - interpreting visual inputs takes a lot of brain power, and might be one of the factors pushing for greater intelligence. So, there’s at least a decent chance that intelligent aliens would have good eyesight.
Also, they’d need hands, or something equivalent.
Once you have hand(equivalent)s, decent eyes, and intelligence, hand-eye-coordination isn’t far off.
If elephants can figure out how to throw rocks with enough force to kill a child, then so can E.T.
