Wearing contact lenses, especially in a world of less sleep and more computer use, makes it more challenging for the eyes to stay comfortable and healthy. To care for your lenses and your eyes, a lens care solution that works like your eyes was created: Biotrue Multi-Purpose Solution moistens in a way your eyes do as it uses a lubricant also found in your eyes, and it is pH balanced to match healthy tears. Biotrue Multi-Purpose Solution helps prevent certain tear proteins from denaturing for clean lenses and fights germs for healthy lens wear. Made in the USA.
