I walked in on the recommendation of my friend. I asked them to adjust my glasses--and the adjustment was worse! I think the assistants need some training. I made an appointment and came back to have my eyes examined. Dr. Wang was very professional and thorough in the exam, and very informative. I did choose glasses, and they honored my VSP benefits, which helps. Glasses are expensive, and the front desk help with adjustments and selection of frames is critical.
