Artelac contains the active ingredient hypromellose which acts as a lubricant to treat symptoms of dry eye. It is a soothing solution that is used as an artificial tear when the eyes are lacking in tears.
Your eyes will normally produce just enough natural tears to allow them to move easily and comfortably.
If your eyes do not produce enough tears they can become dry, red and painful. Your drops keep the surface of the eye lubricated (moist) when production of tears is less than normal, and has a refreshing, cooling action.
The hypromellose in these drops increases the thickness of the solution which has a moisturising effect and helps the solution to stay in contact with your eye for a longer period of time.
