Since I am professionally all day in air-conditioned rooms, I always have the problem to suffer from itchy and dry eyes / lens. So bad that I seriously considered depose the lenses. As a last attempt I have found the product on Amazon and tested for the product description. Very surprised, I note that wearing while working, especially in air-conditioned rooms has improved many times. I notice the contact lenses only minimally even after eight hours in the eyes and really almost the same feeling as without lenses. It really is highly recommended for clients who suffer from dry eyes and do not want to leave here on the costly counsel of the optician.
