The plant contains a number of bioactive compounds, including iridoids, flavonoids, and tannins, which are thought to be responsible for its medicinal properties. One of the key medicinal uses of eyebright is in the treatment of conjunctivitis. The plant is believed to have anti-inflammatory and astringent properties, which can help to reduce the inflammation and redness associated with the condition. It has also been used to treat other eye conditions, such as blepharitis, styes, and dry eye syndrome.

In addition, overgrazing, trampling, and other forms of disturbance can also negatively impact populations of Euphrasia officinalis. Conservation efforts for Euphrasia officinalis typically involve habitat restoration and management, including the restoration of grassland habitats and the control of invasive plant species. Additionally, monitoring and research are important for understanding the population dynamics and ecology of the species, as well as for developing effective conservation strategies.
