This daily regime is recommended by Empfohlenbausch + Lomb for healthy and comfortable contact lens wear: Always wash and rinse your hands before touching your lenses. Apply at least 3 drops of Biotrue multi-purpose solution to each side of the lens surface and rub gently for 20 seconds. Rinse each side of the lens thoroughly with Biotrue multi-purpose solution for 5 seconds. Place cleaned contact lenses in the lens case and fill with fresh Biotrue multi-purpose solution. Soak for at least 4 hours. Remember to always use fresh solution - discard the solution from the lens container after each use. Your lenses are now ready to wear. If there is still dirt on the lenses, rinse them with Biotrue Multi-Purpose Solution before inserting them. Always follow the instructions of your eye care professional. Based on your individual tear chemistry and lens wear schedule, your optician may recommend additional products or procedures.
