Artelac Advanced is a preservative-free eye drop solution containing 0.2% hyaluronic acid, manufactured by Bausch + Lomb. It comes in a box of 30 single-dose units and is specifically designed for moistening eyes and contact lenses, providing sterile and convenient application. The preservative-free formula makes this product particularly suitable for contact lens wearers and those with sensitive eyes. Each unit is single-use to maintain sterility and prevent contamination. The active ingredient, hyaluronic acid 0.2%, helps provide effective moisturizing and lubrication for dry eyes. The drops can be used both with and without contact lenses. Being preservative-free eliminates the risk of preservative-related irritation that some users may experience with standard eye drops.
