Eye drops are liquid medications designed to be applied directly to the eyes. They are used to treat various conditions, such as dryness, allergies, infections, and glaucoma. The drops come in small bottles with a dropper for easy application, allowing precise dosing to ensure effective treatment. These medications can contain different active ingredients, depending on their purpose. For example, artificial tears help relieve dryness, while antihistamines can alleviate allergy symptoms. It's important to follow the instructions provided by a healthcare professional when using eye drops to ensure safety and effectiveness.
