SportSight GP (paflufocon C) intensely tinted 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, posterior or bitoric surfaces. the posterior curve is selected so as to properly fit an individual eye and the anterior curve 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.The SportSight GP (paflufocon C) intensely tinted rigid gas permeable contact lens material is a thermoset copolymer dervied from fluorosilicone acrylate monomer. The SportSight GP (paflufocon C) intensely tinted rigid gas permeable lenses deliver substantial attenuation of bright light and resultant reduction of glare. SportSight GP lenses help protect against transmission of harmful UV radiation to the cornea and into the eye. All environmental UV radiation (including UVA and UVB) is reduced to less than 1% transmission. Blue light (below 500nm) is reduced to less than 10% in SportSight yellow and SportSight brown or 36% in SportSight gray.
A rigid ophthalmic lens intended to be worn directly against the cornea of the eye to correct refractive vision conditions (e.g., myopia, hyperopia, astigmatism, presbyopia); it is designed to be removed prior to sleeping each night. The device is made of various materials (e.g., cellulose acetate butyrate, polyacrylate-silicone, silicone elastomers) whose main polymer molecules generally do not absorb or attract water but permit diffusion of oxygen (O2) to the ocular surface. The lens may last for years and is a reusable device.
