Filtear is designed to alleviate discomfort associated with dry eyes, such as burning, irritation, and the sensation of a foreign body. The combination of Polyethylene Glycol and Propylene Glycol acts as lubricants, maintaining eye moisture, protecting against injury and infection, and reducing symptoms of dryness. When applied, these ingredients interact with natural tears to form a protective gel layer over the eye surface, promoting a healthy environment that facilitates the repair of damaged surface cells.
