A Clinical Review: Can Nutrition Mitigate Digital Eye Strain?

A Clinical Review: Can Nutrition Mitigate Digital Eye Strain?

Posted by EyePromise on Sep 29th 2022

Digital eye strain (also computer vision syndrome) continues to be a pervasive issue among patients of all ages. With schools focusing more on eLearning and companies offering remote or hybrid work environments, screens continue to be a bigger and bigger part of daily life. More screen time means more patients suffering from digital eye strain, so Dennis Gierhart, PhD, and Pinakin Davey, OD, PhD, FAAO, wanted to know how they could help mitigate these symptoms. Through a clinical review, they used existing trials to determine the potential of nutritional intervention for digital eye strain.

What Is Digital Eye Strain?

According to Drs. Davey and Gierhart, “Digital eye strain is a complex, multifactorial condition that can be caused by excessive screen time exposure to various electronic devices such as smartphones, tablets, e-readers, and computers.” Also known as computer vision syndrome, symptoms of digital eye strain include:

  • Asthenopia (eye strain)
  • Eye fatigue
  • Dry eyes due to less blinking
  • Blurred vision
  • Headaches

These symptoms are common and can be experienced in as little as 20 minutes, though most people begin to notice them after two hours of consecutive screen use.

The Research

Thanks to existing literature, Dr. Davey and Dr. Gierhart knew that oxidative stress and inflammation are major catalysts for several eye health issues, including digital eye strain. Armed with this information, they sought to discover if micronutrients with nutraceutical properties could alleviate the vision-related symptoms of digital eye strain. Specifically, they reviewed Omega-3 essential fatty acids, dietary zeaxanthin and lutein, and anthocyanin photochemicals.

The Findings

After a thorough clinical review, Drs. Davey and Gierhart confirmed their hypothesis: certain nutrients can help reduce symptoms related to digital eye strain! There are copious amounts of clinical trials demonstrating the power of Omega-3s for reducing occasional eye dryness and inflammation. Anthocyanins have antioxidant properties and may protect against headaches and eye strain caused by prolonged screen use. Finally, supplementing with dietary zeaxanthin and lutein have demonstrated benefits for cognitive function and overall visual performance, both thought to help reduce the impact of digital eye strain.

The Solution

Although Drs. Gierhart and Davey complete their review by calling for more clinical studies, their research demonstrates a clear positive correlation between these nutrients and digital eye strain symptoms. Therefore, one can say that it certainly wouldn’t hurt for patients to begin adding these nutrients to their diets, either through food or supplementation. EyePromise® Screen Shield™ Pro offers these ingredients and more – all aimed at reducing the symptoms experienced after screen use!
