Presbyoptic patients get clear, irritant-free vision from their Focus Dailies Progressive contact lenses because they are replaced with new lenses every day, avoiding the buildup of deposits that can irritate your eyesight and cloud your vision. You will be able to locate your lenses in the cleaning solution with ease because of the light tint they are infused with.
The lens material is nelfilcon A polymer (polyvinyl alcohol partially acetalized with N-formylmethyl acrylamide).
