What Is Computer Vision Syndrome?

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 After Prolonged Screen Use
Occasionally 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.
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. Which are you looking for?

Why Do Our Screen Time Prodcuts Give You The Edge?
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 recongnizes 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.

We know what you’re thinking. “Where’s the proof?” We’ll spare you the long scientific rambling, but here’s a few of the clinical results
  • It's been shown that taking 8 mg of zeaxanthin can improve visual sharpness and clarity. Read the study!

  • This research shows that dietary zeaxanthin and lutein directly protect the retina from blue light. Read the study!

  • This clinical trial proved that eyestrain increases after spending 60 minutes on a smartphone. Read the study!

  • This research reviews the existing literature detailing damaging blue light's impact on ocular health while weighing the benefits of blue light for impacting sleep regularity. Read the study!

  • These researchers looked at the impact supplementing with fish oil, bilberry extract, and lutein has on eye strain, and they found that it can help with strain and mental fatigue. Read the study!

  • Another study found that supplementation with lutein may help relieve some visual fatigue related to screens. Read the study!

  • The results of this study simply prove that blue light is indeed dangerous to the retina and our vision. Read the study!

  • The researchers in this study found that supplementing with the macular antioxidants (zeaxanthin and lutein) improved vision in bright light situations. Read the study!

  • When supplementing with the macular carotenoids (zeaxanthin and lutein), subjects experienced increases in contrast sensitivity, among other improvements. Read the study!

  • This research found that near visual activities (like using a tablet or smartphone) increases the likelihood of nearsightedness in kids ages 7-12. Read the study!

  • There is a positive link between increased macular pigment and academic performance in children. Read the study!

  • It's well documented that blue light impacts our sleep cycles, but this research shows that using an eReader at night throws off sleep patterns and affects next-day alertness. Read the study!
