Euphrasia Officinalis’ (Eyebright) astringent properties account for its usefulness as a topical treatment for under-eye puffiness and dark circles. It counteracts inflammation and reduces mucous drainage, thanks to its high levels of iridoid glycosides, flavonoids, and tannins.
Eyebright was and continues to be used primarily as a poultice for the topical treatment of eye inflammations, including blepharitis, conjunctivitis, and styes. It’s known to give rapid relief from redness, swelling, and visual disturbances in eye infections, although should only be used under doctor’s supervision when used as a treatment for an eye infection.
Due to limited information on the active constituents in eyebright and the need for sterility in substances used topically in the eyes, the traditional use of eyebright as a topical compress currently cannot be recommended.
A plant; although the name sounds like it would be beneficial for the eye area, there are no studies demonstrating it has any benefit for the eye area or skin. The information about this plant’s effect on the skin or the eye is strictly anecdotal and ophthalmic use may be harmful (Source: www.naturaldatabase.com).
