Hi Zoey, you can check the total width of your current suitable glasses. If the total width is less than 129mm, choose Small. If it is between 129mm-135mm, get the Medium size frames. Any questions, feel free to Live Chat with us. 

Hi Mehrenn, thanks for your interest. Unfortunately the frame size is fixed and we only have the M size. Would you please check our similar styles? Such as LYC1233. 

Salut Papy, cela prend 6-12 jours au Canada. Pour toute question, n'hésitez pas à discuter en direct avec nous. Merci!

Hi Jannatul, thanks for your inquiry. If you have a strong prescription, it would be best to choose a higher (thinner) lens index to avoid any discomfort, but yes, the frame is suitable for those with a strong prescription. It would be best for us to look at your prescription so we can provide recommendations. Please feel free to contact us if you need further assistance on this matter, you may also call our toll-free hotline at 1-855-487-6006 opens every day from 5am - 8pm PST.
