Paragon Thin

Paragon Thin


Paragon Thin 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 an eye care practitioner, some patients may be able to wear them as extended wear lenses for up to a week.  The posterior curve is selected so as to properly fit an individual eye and the anterior curve is selected to provide the necessary optical power to correct Refractive error. A peripheral curve system on the posterior surface allows tear exchange between the lens and cornea.  Paragon Thin lenses are manufactured with a visible tint to assist in locating them in the solution.

   


Lens Material
The Paragon Thin rigid gas permeable contact lens material is 100% Polymer (paflufocon D); a thermoset copolymer derived from fluorosilicone acrylate monomers.
