If you need to change your prescription, you will need to send us an email at firstname.lastname@example.org. Keep in mind the following:
In some cases, lenses may get sent to our manufacturer before a backer is able to update the information. This typically occurs when a backer does not submit updated information by the deadline we provide via email. This is an unfortunate risk of the crowdfunding process, since we have to schedule lens manufacturing weeks to months in advance of delivery.
If you think your prescription might change, the safest thing to do is to email us ASAP to put your lenses on hold.
