Dear Alan,
Thank you for reaching out to us for help.
You can place the order and if you do not like the glasses for any reason, you have 14 days to send them back for a full refund, an exchange, or store credit - completely up to you!
Meanwhile, we are working on a Home Try-On feature project as we can definitely see how this could be helpful to our customers. So stay tuned for what's coming!
Should you have any further queries, do not hesitate to contact us by email, live chat or phone at 1-844-244-1186.
Best Regards,
GlassesUSA
