Lower concentration beta blockers have a blue cap.

Explanation:
Color coding on eye-drop bottles helps differentiate concentrations at a glance, reducing dosing mistakes. For beta-blocker drops used in glaucoma, the lower concentration is typically paired with a blue cap. This visual cue helps ensure the gentler option (for example, timolol 0.25%) is recognized quickly and used correctly, which is important because lower concentrations can reduce the risk of systemic side effects like slowed heart rate or low blood pressure. Keep in mind that cap color conventions can vary by brand and region, so always confirm the strength on the label in addition to the cap color.
