I had my eyes tested by Diane. She took time with me and I felt like I could relate to her. She explained everything so well. You only have one set of eyes. She even handed me my RX at the end with no pressure to buy. I was referred to her from Green Eyewear Optical on George ST. So I ended up returning to purchase my glasses there. Their glasses and customer service are the best I have experienced in 35+ years of buying glasses and they give a percentage of every sale to a local non-profit.
