I've recently started going to Norwalk Vision Center. It's not in Stamford, but only a 20 min drive or so. They were amazing in terms of eye exam and helping me pick a pair of glasses. I wanted a pair of ray ban sunglasses that they didn't carry in store so the receptionist called and had a trial pair shipped for me before ordering the prescription so I could try them on.

I'd deff check out what benefits your insurance offers before you go! Mine offers a 150 allowance towards lenses, than an additional 20% off any amount over that (30% if you buy same day as your appointment).
