TraditionWARNING: DISCLAIMER: The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Adults (over 18 years old)
There is no proven safe or effective dose of eyebright. Traditionally, 2-4 grams of dried herb three times daily has been suggested for multiple indications. For conjunctivitis (pinkeye), one drop of eyebright 1-5 times daily for 3-17 days has been studied.
Children (under 18 years old)
There is no proven safe or effective dose of eyebright in children. However, children have tolerated 4-5 homeopathic pills of Euphrasia 30C daily for three days for prevention of viral conjunctivitis.
SafetyDISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
Avoid in individuals with a known allergy or hypersensitivity to eyebright. Hypersensitivity to members of the Scrophulariaceae family may lead to a cross-sensitivity reaction.
Side Effects and Warnings
Systematic study of clinical safety and tolerability has been limited. Both children and adults have tolerated short-term ophthalmologic use of eyebright for conjunctivitis (pinkeye). However, the potential exists for contamination of ophthalmologic preparations of eyebright, and eyebright tincture has been associated with pruritus (severe itching), redness and swelling of the eye, vision changes, and photophobia (intolerance or fear of light). Other adverse effects reported include toothache, confusion, headache, sneezing, yawning, insomnia, raised ocular pressure, lacrimation (tears), cough, dyspnea (difficulty breathing), nasal congestion, hoarseness, nausea, constipation, expectoration, polyuria (excessive urination) and diaphoresis (excessive sweating).
Eyebright is possibly safe when used in amounts commonly found in foods, or when eyebright is used as a flavoring agent.
Eyebright is likely unsafe when "home-made" preparations are used for ophthalmic indications, due to the likelihood of microbial contamination; when used in greater than studied doses or duration due to lack of safety data; and when used during pregnancy and breastfeeding, or in pediatric patients.
Although not well-studied in humans, eyebright may lower blood sugar levels. Caution is advised in patients with diabetes or hypoglycemia, and in those taking drugs, herbs, or supplements that affect blood sugar. Serum glucose levels may need to be monitored by a qualified healthcare professional, including a pharmacist, and medication adjustments may be necessary.
Pregnancy & Breastfeeding
Eyebright is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.
