Dear Customer, thank you for your comments and we are sorry to hear that. I'm afraid that each frame has a fixed size and we are unable to customize it. We have different frame suppliers and they have different measuring methods, so we re-measure the frame size and upload it to the website. Therefore, you could rely on the measurement listed on the frame page. We understand that choosing a perfect frame size online can be tough sometimes so we suggest that you could please check this link https://www.firmoo.com/help-p-1.shtml
for reference. Please don't worry, we offer a 30-day return&exchange
in which unsatisfied glasses can be exchanged or refunded within 30 days of receiving. Only shipping fees will apply. Please feel free to contact us if you need. Stay safe and healthy!
