HelloPharmacist Scorecard of Eyebright by Solgar

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 30, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Solgar Eyebright contains 2 active ingredients: eyebright extract and raw eyebright powder. Both come from the eyebright plant, a traditional herb used for eye and respiratory health.

The capsules also contain vegetable cellulose and vegetable magnesium stearate as inactive ingredients (common binders and fillers).

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Eyebright's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: eye health and comfort support.
  • We looked for evidence on: Asthenopia (eye strain), Conjunctivitis, Allergic rhinitis (hay fever), eye irritation, ocular redness.
  • The closest evidence on file: Eyebright is rated "Insufficient Reliable Evidence To Rate" for Allergic rhinitis (hay fever) (Natural Medicines).
  • Also on file: Eyebright is rated "Insufficient Reliable Evidence To Rate" for Asthenopia (eye strain), Conjunctivitis.

The evidence for eyebright isn't established yet. Our data shows insufficient reliable evidence to rate it for allergic rhinitis (hay fever), common cold, cough, pharyngitis, rhinosinusitis, or cancer.

That doesn't mean it doesn't work—it means clinical trials haven't built a strong enough case to confirm it does. If you're considering this for a specific condition, talk with your doctor about whether the current evidence supports a trial.

The evidence, ingredient by ingredient Eyebright

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Taken by mouth, eyebright has been reported to cause confusion, headache, nausea, constipation, cough, shortness of breath, and nasal congestion. The product is likely safe in small amounts as a tea, but do not apply homemade or non-sterile preparations directly to the eye—that carries real risk.

During pregnancy, safety hasn't been established, so it's best avoided. While breastfeeding, there isn't enough safety information to know either way; talk with your doctor or pharmacist for personalized advice.

Side effects, ingredient by ingredient Eyebright

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Eyebright.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check with your doctor or pharmacist if you take any antidiabetes medications. Eyebright may lower blood glucose, and combining it with your diabetes drug could raise the risk of low blood sugar.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Solgar Eyebright is traditionally used for eye health, but clinical evidence for its effectiveness isn't yet strong enough to confirm. The main thing to watch for is interaction with diabetes medications, which could lower your blood sugar further.

If you take any diabetes drug, check with your doctor or pharmacist before you start. Pregnant or breastfeeding?

Same conversation is worth having.
