Artificial tears play a crucial role in eye care primarily by providing lubrication to the eyes. They mimic the natural tears produced by the body, which are essential for maintaining moisture on the surface of the eyes. This lubrication helps to alleviate symptoms of dryness, irritation, and discomfort that can arise from various conditions, such as dry eye syndrome or exposure to environmental factors.

By maintaining an appropriate level of humidity and moisture in the eyes, artificial tears facilitate smoother eye movements and can enhance comfort during activities that may otherwise lead to dryness, such as prolonged screen time or contact lens wear. Additionally, adequate lubrication supports the overall health of the ocular surface, reducing the risk of damage from friction and environmental irritants.

This function of artificial tears is essential in eye care, especially for individuals who experience reduced tear production or impaired tear quality.
