Over the counter eye drops are categorized into how many groups?

Over-the-counter (OTC) eye drops are typically categorized into three main groups based on their intended use and therapeutic action. The first group includes lubricating eye drops, often used to relieve dryness and irritation by providing moisture to the eyes. The second group consists of antihistamine eye drops, which are used to alleviate allergy symptoms such as itching and redness. The third group is comprised of decongestant eye drops, aimed at reducing redness caused by minor irritations by constricting the blood vessels in the eye.

Understanding these categories is essential for pharmacy technicians, as it allows them to recommend appropriate products based on a patient's symptoms and needs. Being aware of the different types of eye drops ensures safe and effective patient care by helping to address specific ocular conditions with the correct formulation.
