Screens Causing Eye Fatigue?
Give Bilberry a try.
These little blue fruits (Vaccinium ulginosum) known also as European blueberries, have been used in herbal medicine for centuries, but it wasn't until World War II that the herb's real value was discovered - not by scientists, but by aviators. During the war, British flyers ate bilberry jam before nighttime bombing missions, swearing that the berries sharpened their vision. After the war, researchers began studying the berry and discovered that it does indeed improve night vision and help the eyes adjust to glare, thanks to high levels of antioxidant nutrients that help prevent damage to the optic nerve. Since then bilberries have also been shown to reduce the risk of cataracts, glaucoma and macular degeneration. So South Korean researchers wondered if the berries might also help with leading 21st century eye problems: eyestrain, fatigue, blurred vision and headache caused by excessive screen time.
The researchers assessed eye fatigue in 60 volunteers, ages 20 to 65 who had no eye disease and viewed computer or phone screens for at least two hours a day. Half the participants took a placebo, while the other took 500mg bilberry a day. After 4 weeks, the researchers assessed everyone's eye scores. The bilberry group showed significantly less fatigued, achy, irritated, watery or dry eyes, and less eyestrain and blurred vision. The study was published in BMC Complementary and Alternative Medicine.

Bilberry is not the only fruit high in antioxidants. Pretty much all colorful berries contain similar amounts. If you're bothered by eyestrain, or computer/phone screen fatigue, try a handful of these daily. In addition to minimizing symptoms, a diet high in antioxidant nutrients also reduces the risk of heart disease, most cancers and many other degenerative conditions.
