I got an Alto Frame for Xmas 2019 and want to order replacement lenses but there are two sizes listed, s-m and m-l. There is no indication on my box, label, or anywhere that I can find telling me which one I have. Does this mean I have an older model before the small version was released, and if so is it the same as the current m-l size compatible with the replacement lenses on the website?
Thank you for posting and reaching out to us today!
This is correct, you have the first model that was created before the sized versions were released. This means that your Frames are the S/M sized version, so they are only compatible with the smaller replacement lenses.
I hope this helps and if you have any other questions, please do let us know.
