Artelac contains the active ingredient Hypromellose, which acts as a lubricant to treat symptoms of dry eye. Your eyes normally produce just enough natural tears to move easily and comfortably. If your eyes don't produce enough tears, they can become dry, red, and painful. Artelac helps keep the surface of the eye lubricated when tear production is less than normal, providing a soothing and refreshing action. The Hypromellose in these drops increases the solution's thickness, allowing it to stay in contact with your eye for a longer period. Artelac can be used by children, adults, and the elderly as an artificial tear solution.
