Saline solution, a type of contact lens solution, plays a crucial role in maintaining eye health and lens hygiene. Composed primarily of sterile water and salt, it is used to rinse, store, and hydrate contact lenses before wear. By effectively removing debris and protein buildup, saline solution helps prevent corneal abrasions, eye irritation, and bacterial infections. It is particularly suitable for users with sensitive eyes or those who experience discomfort with multipurpose solutions.
