Nearsighted (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
myopic
'nearsighted' is the definition.
(similar in meaning)
This is all the clue.
(Other definitions for myopic that I've seen before include "Short-sighted" , "Condition of short-sightedness" , "Imprudent" , "needing help from lens" , "Nearsighted" .)
