- Prescription renewal
- Prescription verification

# Prescription Renewal

By leveraging Visibly's vision test, contact lens and glasses retails can provide their users with the ability to renew their prescriptions online.

There are two ways to start a Visibly vision:

1. Visibly-hosted page
2. Visibly API integration


## Using a Visibly-Hosted Page to Start a Vision Test

Use a Visibly-hosted page to start a vision test for a full-featured experience with minimal integration effort, features include:

- White-labeled branding, logo and color pallete
- Capable of collecting patient information on behalf of the retailer
- Configurable via query string parameters


## Using the Visibly GraphQL API to Start a Vision Test

Use `startVisionTest`...

# Prescription Verification

The [Contact Lens Rule](https://www.ftc.gov/legal-library/browse/rules/contact-lens-rule) mandates that a contact lens seller must verify the prescription associated with a contact lens order prior to fulfilling it. Visibly provides the ability to do that via its GraphQL API.

Use `verifyContactsPrescription` and `verifyGlassesPrescription`...

# Order Fulfillment for Contact Lens and Glasses

Use `submitOrder`...
