Artificial tears are specially formulated eye drops that help to supplement the eye’s natural tear film. The tear film is a complex mixture of water, lipids, and proteins that coat the surface of the eye, keeping it moist, smooth, and free from irritants. When this tear film becomes unstable due to factors like age, environmental conditions, or underlying health issues, it can lead to dryness, irritation, and discomfort.

Artificial tears come in various formulations, from simple saline solutions to more advanced drops that contain ingredients like electrolytes, lubricating agents, and even oils that help stabilize the tear film. These drops work by replenishing moisture and providing a protective layer over the eye’s surface, temporarily relieving the symptoms of dry eye.
