About VISMED & Dry Eyes Vismed Light Eye Drops 15ml Vismed Light Eye Drops are a gentle, p H balanced solution for mild dry eye symptoms. A multidose bottle of Vismed Light contains 15ml of 0.1% sodium hyaluronate. How to use Vismed Light Twist the screw cap on the multidose container firmly clockwise before using Vismed Light for the first time: a spike in the screw cap will pierce the tip of the container. Twist off the screw cap & position the tip of the container above the eye to be treated: upon slight pressure, Vismed Light will easily flow out of the container. If not otherwise recommended, place one or two drops of Vismed Light into the conjunctival sac of the eye as often as needed. After blinking, the solution will disperse & form a transparent & long-lasting coating on the surface of the eye. Vismed Light may also be used while wearing contact lenses (rigid or soft). Solution from the open container may be used for up to 3 months.
