A meadow herb that folk medicine has used on eyes for centuries.
Retina ClearIn plain words
Eyebright (Euphrasia) is a small semi-parasitic plant. Old herbals recommended it for sore, watery, tired eyes.
Retina ClearWhat the evidence shows
Modern proof is slim. A few small trials of eyebright eye drops in conjunctivitis reported relief, but they were small and cannot support firm claims. Evidence for a swallowed capsule is essentially absent.
In this capsule
The seller lists the aerial part of the plant with no dose.
Watch-outs: Never put a homemade herbal wash in your eye; contaminated washes can cause serious infection. Oral use is thought low-risk but poorly studied.
Common question
Is eyebright backed by science?
Mostly by tradition. There is little clinical evidence.
