Paragon RG-4 contact lenses are manufactured from Paragon HDS® 100. The reverse geometry design has a posterior surface consisting of four zones: The central spherical or aspheric zone, an annular “Reverse Zone(s)”surrounding the central zone with a curvature steeper (shorter radius) than the central zone, an “Alignment Zone(s)” generally paralleling the underlying corneal surface and peripheral curve(s) with a radius selected to create “edge lift” to promote tear flow under the lens and avoid impingement of the peripheral curve on the cornea.The lens design also includes a “rounded” edge terminus extending from the anterior to the posterior surfaces to promote comfort.Paragon RG-4 Contact Lenses for Corneal Reshaping are to be worn overnight with removal during all or part of each following day. The material is a thermoset fluorosilicone acrylate copolymer derived primarily from siloxane acrylate, trifluoroethyl methacrylate and methylmethacrylate with a water content of less than 1%. These contact lenses for corneal reshaping are available as lathe cut firm contact lenses with blue, green, red and yellow tints containing D&C Green No. 6, D&C Red No. 17 and Perox Yellow No. 9 (4-[(2,4-dimethylphenyl)azo]-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-one). These products may be plasma treated.

Paragon Z CRT Dual Axis contact lenses are manufactured from Menicon Z® (tisilfocon A). The lenses are designed to have congruent anterior and posterior surfaces each consisting of three zones: The central spherical zone, a mathematically designed sigmoidal corneal proximity “Return Zone" and a non-curving “Landing Zone”.The lens design also includes a convex elliptical edge terminus smoothly joining the anterior and posterior surfaces.Paragon Z CRT Dual Axis Contact Lenses for Corneal Refractive Therapy are to be worn overnight with removal during all or part of each following day. The lens material (tisilfocon A) is a thermoset copolymer derived from fluoro-methacrylate and siloxanylstyrene bound by crosslinking agents. The lenses for Corneal Refractive Therapy are available as lathe cut firm contact lenses with a light blue tint. The blue tinted lens contains D&C Green No. 6. A UV absorber (Benzotriazol) is added as an additive during the manufacturing process.

Paragon HDS® (paflufocon B) rigid gas permeable contact lenses for daily wear are available as lathe cut or molded firm contact lenses with spherical, aspheric, bifocal or toric anterior and/or posterior; or, bitoric surfaces in tinted versions. Paragon HDS® rigid gas permeable contact lenses for extended wear are available as lathe cut or molded firm contact lenses with spherical or aspheric anterior or posterior surfaces in tinted versions. 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 the cornea.The Paragon HDS® rigid gas permeable contact lens material is a thermoset copolymer derived from fluorosilicone acrylate monomers.The Paragon HDS® rigid gas permeable tinted lenses offer color enhancement of the eye and a handling aid for locating the lens. These products may be plasma treated.
