The Giselle (polymacon) Spherical Soft Contact Lenses for daily wear are indicated for the correction of visual acuity in aphakic and not aphakic persons with non-diseased eyes with myopia or hyperopia. The lens may be worn by persons who exhibit refractive astigmatism of 0.50 diopters or less where the astigmatism does not interfere with visual acuity. The lens is available clear or tinted and may be used to enhance or alter the apparent color of the eye. Daily wear replacement schedules may vary from patient and should be decided by eyecare practitioners in consultation with their patients. Frequent/Planned Replacement Wear: Eyecare practitioners may prescribe any of the above lenses for frequent/planned replacement wear, with cleaning disinfection and scheduled replacement. When prescribed for frequent/planned replacement wear, the lens may be disinfected using a chemical disinfecting system. Disposable Wear: Eyecare practitioners may prescribe any of the above lenses for Daily Disposable Wear. When Prescribed for Daily Disposable Wear the lenses are not to be used with disinfecting systems as they are to be discarded after a single use.

The Giselle soft contact lenses are hemispherical shells with molded spherical base curves and molded front surfaces. The Giselle soft contact lenses are fabricated from polymacon, which in the dry (unhydrated) state may be machined and polished. The hydrophilic nature of this material allows the lens to become soft and pliable when immersed in an aqueous solution. The nonionic lens material, (polymacon) is a hydrophilic polymer of 2-Hydroxyethyl methacrylate (2-HEMA) and cross-linked with ethylene glycol dimethacrylate (EGDMA), plus an initiator. The co-polymer consists of 62% polymacon and 38% water by weight when immersed in saline solution. The (polymacon) name has been adopted by the United States Adopted Names Council (USAN). Giselle lenses are available clear, visibility tinted, and tinted to enhance or alter the apparent color of the eye (opaque tinted lenses). Clear or tinted lens designs may be distributed under unique or "private label" trade names. Giselle lenses are tinted with one or a combination of one or more of the following 'listed' color additives: D&C Yellow 10, D&C Green 6, Titanium Dioxide. Iron Oxide (Red). C.I. Reactive Blue 19, and C.I. Reactive black 5. Lenses that contain a unique tinting pattern are subsequently processed to incorporate the 'listed' color additives, and contain only the amount of color additive needed to accomplish the intended coloring effect. When producing the opaque tinted lenses, the manufacturing process alters and/or changes the specifications to the clear version of a contact lens via entrapment of a listed color additive in the center of the contact lens (between lavers of contact lens material) in a location that corresponds to the iris. The color additives used are not removed by lens handling and cleaning/disinfecting procedures. Except for affecting the amount of light transmittance through the lens, the coloring process does not alter the original characteristics of the pre-tinted lens. The opaque tinting pattern has a minimum clear pupil diameter of 6.0 mm. In the hydrated state, the lens conforms to the curvature of the eve covering the cornea and extending slightly beyond the limbus forming a transparent or colored optical surface. The (polymacon) soft hydrophilic contact lens has a spherical back surface. The hydrophilic properties of the lens require that it be maintained in a fully hydrated state in a solution compatible with the eye. If the lens dries out, it will become hard appear somewhat warped; however, it will return to its proper configuration when completely rehydrated in the proper storage solution.
