Having trouble seeing the old photo of me (6)
I believe the answer is:
myopic
'having trouble seeing the old photo of me' is the definition.
I can't judge whether this defines the answer.
'having trouble seeing the old photo' is the wordplay.
'having trouble' becomes 'my' (I can't explain this - if you can you should believe this answer much more).
'seeing the old' becomes 'o' (abbreviation as in OT - Old Testament).
'photo' becomes 'pic' (short for picture).
'my'+'o'+'pic'='MYOPIC'
Can you help me to learn more?
(Other definitions for myopic that I've seen before include "Imprudent" , "Nearsighted" , "Unable to focus on distant objects" , "needing help from lens" , "Condition of short-sightedness" .)
