Paragon HDS contact lenses from Paragon Vision Sciences are gas permeable lenses designed to be worn as daily wear lenses and replaced after up to a year of use, depending on advice from your eye care practitioner.  The lenses are made with materials that utilize a proprietary hyper puffed delivery system to purify the material’s silicone content, offering one of the most efficient lens materials in the industry.  Paragon HDS lenses are manufactured with a visible tint to assist in locating them in the solution.
