Eyebright (lat. Euphrasia officinalis) belongs to the genus Euphrasia of the Orobanchaceae family. The genus includes 241 species. For a long time, many European species were united under one name -.

In addition, this herb is able to grow without the help of haustoria, although it develops much more slowly. The stem is straight, sometimes strongly branched, and reddish-brown in color. Eyebright leaves are small, ovate, toothed. At the bottom of the stem, they quickly fall off.

After pollination seed boxes with many oblong small seeds ripen on Eyebright.
