    My first pair of prescription glasses ordered three yes and I’m very happy with the fit and the progressive readers are a seamless transition from reading day-to-day activities. I’ve also never had a pair of transitions and they were great moving from bright light sunshine to inside. Granted, I’ve only been wearing them for 24 hours, but super satisfied.

    I love the look of these glasses. They are so light I forget I'm wearing them. The price is reasonable too. Because of the savings on this pair, I ordered two more. And the shipping was so quick. I would definitely order again!

    The frames look and feel great. I appreciate the high-quality material. I'm ordering a second pair in a different color.
