iVIZIA Eye Drops provide long-lasting dry eye relief by combining ingredients proven to target every point in the vicious dry eye cycle:

  • Hyaluronic acid, a component of the tear film with the ability to lubricate, can bind 1000 times more water than its weight.

Clinical studies have shown that the combination of 3% trehalose and 0.15% hyaluronic acid found in both dry eye products:

  • increased tear thickness to 240 minutes from a single application 76 times longer than hyaluronic acid alone

  • provided the majority of patients with greater improvement in scores on the Ocular Surface Disease Index5 compared to hyaluronic acid alone

  • decreases inflammation of the ocular surface; and

  • relieves symptoms including blurred vision, stinging and itching.5
