Contact lens users who value convenience and comfort will be delighted with these great continuous wear contact lenses. Thanks to reliable silicone hydrogel material that Biofinity contact lenses are made of, they let your eyes breath and retain their moisture for up to 7 days and 6 nights non stop. You don't need to worry about taking them out for the night and storing them in a solution - just pop a pair in and keep it in for the next week. After that, all you need to do is clean them and you can wear them continuously again! Thanks to their high oxygen permeability and the ability to stay moist, you don't need any extra rewetting eye drops while wearing Biofinity contacts.
