As the name implies, per, eyebright is best known for its various uses in treating eye ailments. Records from the Middle Ages indicate that the plant was believed capable of curing all evils of the eye. Well, while we can't vouch for what determines evil in our modern era, we do know that some of the conditions it has been linked to in terms of inducing healing properties are conjunctivitis ( pink eye ), eye ulcers, weak vision, and eye strain and even such issues as itching, burning, and teary eyes, like those associated with spring allergies.

Scientific research pinpointing eyebright's reported health benefits is relatively scarce and ongoing, although there are studies that have been done and bear outs its effectiveness. One study published in 2000 in Journal of Alternative and Complementary Medicine, cited at, took a look at eyebright's efficacy in treating conjunctivitis. What it found in the treatment of 65 people with the condition was that eyebright-containing eyedrops administered one to five times a day was accompanied by a complete recovery of 53 of the patients within 14 days. Another study published in 2014 involving tests on cells extracted from the surface layer of human corneas identified the aforementioned anti-inflammatory properties of eyebright.
