A bit flimsy, but looks perfect! Would recommend.

These glasses are honestly so cute! This is my second pair of glasses from Firmoo and I was skeptical at first, but I loved my first pair so I went ahead and got these ones. They aren't super flimsy, are extremely lightweight, and don't slip off your face when just walking around (which is pretty important in my profession). Will be buying more frames off of this site. Thank you, Firmoo!

Ask A Question
Is there any way I can purchase this pair of glasses with the old frame sizes? Because I have bought many of this pair a long time ago and now I just purchased this pair again but didn't know that the size of the frame has changed. I thought it would be the same size until I try to put my lenses on and couldn't place it right then I realized you changed the size of the frame. Why didn't you just put it a new pair of glasses with new codes? (1 Answer)

Thanks for your suggestion and sincerely sorry about the inconvenience.
Different batches will come with a little difference on size but within  ±0.5mm is allowed.
Kindly be aware glasses are medical products. A perfect frame size is as important as a correct prescription. We advise you to try our lens together with frame to ensure good wearing experience. And the prescription on your old lens may not function well as daily wear and tear and changes on your latest prescription.heart

Moreover,  unsatisfied glasses can be exchanged or refunded within 30 days of receiving. Only shipping fees will apply. Each order is eligible for a one-time exchange/return.
