What Is Visual Performance?
Visual performance is the ability for the eyes to function to the best of their ability. Factors that can affect visual performance include:
Visual acuity
Contrast sensitivity
Glare recovery
Photostress recovery
Visual processing speed
Improving Visual Performance Through Nutrition
Certain visual functions are heavily impacted by the nutrients in food. Foods that contain ingredients like zeaxanthin, lutein, Vitamin A, Vitamin D, and Omega-3s are all great additions to the daily diet.
The Solution
While these nutrients are found in food sources, they are surprisingly scarce in the Standard American Diet. Even if patients do eat their share of leafy greens and brightly colored vegetables, they’d need to eat 20 ears of corn a day to get the amount of zeaxanthin their eyes need to improve and maintain visual performance.

Supplementation can help fill this all-too-common dietary gap. EyePromise is the #1 eye vitamin brand in professional, collegiate, and Olympic sports, and we’ve created a line of eye health nutraceuticals dedicated to patients looking to improve their performance from the eyes down. EyePromise’s performance vitamins are of the highest quality and NSF Certified for Sport.

Why do our visual performance products stand out?

This critical antioxidant is chosen by the retina to protect central vision. Additionally, zeaxanthin is accumulated in the fovea (center of the retina) 2 times more than lutein. While the eye itself chooses to include more zeaxanthin in its own protection, most eye vitamins choose to match the ratio found in the diet, which is 5 to 1 lutein to zeaxanthin. EyePromise recognizes the importance and scarcity of zeaxanthin and, therefore, chooses to include 4x more than other products.
While zeaxanthin is extremely important, lutein is no scrub. This antioxidant plays an important role in protecting vision from dangerous blue light, and it's been found to help support many other parts of the body.
