Correct your vision while you sleep with safe, non-surgical Paragon CRT therapeutic lenses, and enjoy great vision 24 hours a day, without the hassles of glasses and daytime contacts.

Corneal refractive therapy is a non-surgical treatment that gently reshapes the surface of your eyes to correct your vision. While you sleep, specially design contacts painlessly reshape the corneal surface to correct your vision. When you wake, you can remove the CRT contacts while their reshaping effect continues to provide clear, natural vision throughout the day without the need for corrective lenses.
