Visit your medical optometrist for primary medical eye care, including eye medication prescriptions, monitoring and managing eye diseases, or emergency eye care services. Visit an ophthalmologist for interventions like surgical treatments for serious eye diseases, advanced ocular problems, or refractive eye surgery.

Opticians are technicians who fit eyeglasses, contact lenses, and other vision-correcting devices. Optometrists examine, diagnose, and treat patients' eyes. Ophthalmologists are eye doctors who perform medical and surgical treatments for eye conditions.

Luxottica retails its products through stores that it owns, predominantly LensCrafters, Sunglass Hut, Pearle Vision, Target Optical, and Glasses.com. It also owns EyeMed, one of the largest vision health insurance providers.

If you use a Costco, Wal-Mart or other non-network provider, you will need to pay the entire bill at the time services are provided and submit a completed claim form to EyeMed Vision Care. For services at all Costco and Wal-Mart optical locations, you'll receive reimbursements equivalent to in-network benefits.
