Since all Sightbox memberships are 12 months, they are not intended for people who want to "try out" contact lenses. If you decide to cancel your membership because you cannot or do not want to wear contacts, you are still obligated to pay the full balance of benefits received according to the Terms of Service agreed to in all Sightbox memberships.
If you are a current member and you are interested in receiving your cancellation details, you can get in touch with our Support Team at firstname.lastname@example.org, or you can message us via chat on any www.sightbox.com page.
Are you sure that contact lenses are right for you? If so, you can get started here.
