Programs Overview

Our business is developed around zeaxanthin and high-quality nutraceuticals to help manage AMD risk and preserve healthy vision. EyePromise offers three programs featuring nutraceuticals designed to help your patients and your practice – all with free ongoing support: 


QuantifEye® Program

QuantifEye is our premiere program that includes EyePromise nutraceuticals, QuantifEye MPOD Measurement Instrument, and ESP EyeCare Support Program.


EyePromise Dispenser Program

Dispense the EyePromise brand of nutraceuticals out of your office with no minimum case buy-in, inventory requirements, or ongoing commitment – simply place your case orders (24 bottles per case), as needed.


EyePromise Prescriber Program

Recommend or “prescribe” EyePromise nutraceuticals to patients without carrying them in your practice -patients order directly from ZeaVision, and you earn a consultation fee on every bottle ordered.
