According to the National Institutes of Health, fluorescein is a diagnostic contrast agent used in various ophthalmic procedures, not an anesthetic. The common misconception that **is fluorescein an anesthetic** arises because it is almost always administered with a numbing agent to ensure patient comfort during examinations.

Fluorescein is a diagnostic dye used in countless ophthalmic procedures to detect issues like corneal abrasions [1.2.1]. Contrary to a common belief, the answer to 'Does fluorescein numb the eye?' is no; the numbing effect comes from a separate anesthetic drop used alongside it [1.2.5].

Oxybuprocaine hydrochloride is a widely used topical local anesthetic in ophthalmology, prized for its rapid action [1.4.7]. Understanding **how long does oxybuprocaine take to work** is crucial for its effective use in various eye examinations and minor surgical procedures [1.4.1].

Providing anesthesia in less than a minute, what is oxybuprocaine used for is primarily numbing the eye's surface for short diagnostic and minor surgical procedures in ophthalmology, including tonometry and foreign body removal. This rapid-acting local anesthetic helps ensure patient comfort during various clinical examinations and interventions.
