What Is Computer Vision Syndrome?

As a gamer, you've likely experienced computer vision syndrome, also known as digital eye strain. Computer vision syndrome (CVS) is used to describe the symptoms commonly experienced after spending 2 or more hours on digital screens.

Symptoms include:

Tired eyes

Eye strain

Headaches following prolonged screen use*

Occasional dry eyes*

So, what causes these symptoms? Many experts attribute tired, strained eyes to a type of light emitted by digital screens called blue light. Blue light is a type of visible light that can damage the delicate cells responsible for our vision. Like UV light, blue light has a cumulative effect, meaning that the more you’re exposed to it, the more it impacts your eye and overall health. As an esports athlete, it's difficult to avoid the screen time, but there is something you can do to protect your eyes.

Alleviating Screen Time Symptoms with Nutrition

Few people know that there’s a strong relationship between what you eat and your eye health. Aside from taking frequent breaks, nutritional intervention has been proven to help relieve the common screen-time eye symptoms and increase your eyes’ natural protection against dangerous blue light.

The Solution

Foods that contain ingredients like zeaxanthin, lutein, Omega-3s, Vitamin D, and selenium are all great additions to the daily diet. While they are found in food sources, they are surprisingly scarce in the Standard American Diet. Even if we do eat our share of leafy greens and brightly colored vegetables, we’d need to eat 20 ears of corn a day to get the amount of zeaxanthin our eyes need to keep our blue light protection strong.

Many eye care providers recommend supplementation to fill this all-too-common dietary gap. EyePromise is the #1 doctor-recommended eye vitamin brand, and we’ve created a line of vitamins dedicated to people like you looking for a solution for their screen time suffering.

Why Do Our Screen Time Products Give You The Edge?

Zeaxanthin
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.

Lutein
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.
