1-800 CONTACTS is the world's largest contact lens store. 1-800 CONTACTS sells more contacts every day than Pearle Vision (the largest single optical chain that sells contact lenses). They stock more than 20 million contact lenses and deliver over 100,000 every day directly to customers. Note: 1-800-CONTACTS, as a replacement center, cannot sell you contact lenses that you are not already wearing successfully. Visit an eye care provider for a contact lens exam and prescription and then call them to order your contacts.
