Optometrist Julie Larson, O.D., left, hands patient Sarah Sterling equipment to fine tune her reading glasses in Larson’s office at the Rimrock WalMart. Sterling had congenital cataracts that grew progressively worse until Larson and others stepped in to get her surgery on her eyes. In return, Sterling, a Mesa State college student and artist, plans to paint a mural on a blank wall in Larson’s office.
