Asthenopia (Eye strain)
Supplements studied for asthenopia (eye strain).
Overview
Two supplements are indexed for asthenopia (eye strain) across four studies, both with low ratings (WA 40).
Small bilberry trials reported improvements in eye-focus tests after prolonged screen use, though subjective strain relief was inconsistent. One combination product with bilberry, fish oil, and lutein reduced dry eyes and stiffness, making bilberry-specific effects unclear.
Elderberry was studied only in a multi-ingredient supplement that reduced eye strain over one month; whether elderberry alone helps is uncertain. See the evidence reviews below for details.
