Abstract: A social media advertising system facilitates the auto-population of a symbol, such as a sponsor's logo, in association with a topic or hashtag the sponsor has agreed to promote or support. The sponsor purchases the right to have a chosen symbol displayed when a social media post is published having a specific topic or hashtag. When the topic or hashtag goes viral or becomes a trending topic, the sponsor gets a large amount of exposure in association with a trendy or time sensitive topic. The sponsor can pay for this right by a per use fee, a fee for a predetermined amount of time, or by any other metric. The subtle display of a symbol in this manner does not distract from the purpose or content of the post. The symbol may also serve as an interactive hyperlink to content or a website chosen by the sponsor.

The first portion provides a user interface to the eye care provider for specifying contact lens parameters for the contact lenses and for generating a code associated with the contact lens user. The second portion provides a user interface to the contact lens user for inputting the code to register and then for managing contact lens ordering.
