Eye drops are a type of medication used to treat various eye conditions. They are typically composed of a combination of ingredients, such as preservatives, lubricants, and medications, which are applied directly to the eyes. The term 'eye drops' is often used interchangeably with the term 'TEARS, ' which is a five-letter word that can be used to describe the same product. Eye drops are used to treat a variety of conditions, including dry eyes, allergies, infections, and glaucoma. They can also be used to reduce redness and irritation, and to provide relief from eye strain.
