I got picked up — not a pretty sight (7)

I believe the answer is:
eyesore
'not a pretty sight' is the definition.
(I've seen this in another clue)
'i got' is the wordplay.
'i' becomes 'eye' (I've seen this in other clues).
'got' becomes 'sore' (I can't explain this - if you can you should believe this answer much more).
'eye'+'sore'='EYESORE'
'picked up' acts as a link.
Can you help me to learn more?
(Other definitions for eyesore that I've seen before include "offensive to viewers" , "Blot on the landscape" , "Unpleasant sight" , "Ugly object, hard on the sight" , "Something exceedingly ugly" .)
