The Westcon Horizon™ 49 (hioxifilcon B) soft contact lenses for daily wear that are manufactured from hioxifilcon B lens blanks are lathe cut into a hemispherical shell that are designed to fit over the corneal surface of the eye. These lenses are designed with varying base curves that conform to the shape of the radius of the cornea and center over the apex of the cornea to provide correction of refractive ametropia (myopia, hyperopic, astigmatism and presbyopia) in aphakic and notaphakic persons with non-diseased eyes. The non-ionic lens material, hioxifilcon B, is a copolymer of 2-hydroxyethyl methacrylate (2-HEMA) and 2,3-Dihydrosypropyl Methacrylate (Glycerol Methacrylate, GMA). It consists of 52% hioxifilcon B and 48% water by weight when immersed in normal saline solution buffered with sodium bicarbonate. The Westcon Horizon™ 49 (hioxifilcon B) is made out of hioxifilcon B and is available in clear and with a blue visibility-handling tint, phthalocyanato (2) -(copper). The Westcon Horizon™ 49 (hioxifilcon B) is a lathe-cut soft lens. In the dry (unhydrated) state the lens is machined and polished. In the hydrated state, the lens conforms to the curvature of the eye covering the cornea and extending slightly beyond the limbus forming a colorless, transparent optical surface. In the hydrated state, the Westcon Horizon™ 49 (hioxifilcon B), when placed on the cornea, acts as a refracting medium to focus light rays on the retina. The progressive optics in the Horizon™ 49 progressive designs utilize the simultaneous vision concept which offers functional vision from distance to near throughout the viewing range. The pupil zone on the front surface varies with the size of the patient's pupil.

The color-enhanced version is indicated for daily wear to enhance or alter the apparent eve color. The lenses may be disinfected using chemical systems only.

The soft contact lenses that are manufactured from Hioxifilcon A lens blanks are lathe cut into a hemispherical shell that are designed to fit over the corneal surface of the eye. These lenses are designed with varying base curves that conform to the shape of the radius of the cornea and center over the apex of the cornea to provide correction of refractive ametropia (myopia, hyperopic, astigmatism and presbyopia) in aphakic or not-aphakic persons with nondiseased eyes. Each lens is designed with a base curve on the internal side of the lens and an optical zone in the center of the lens, generally of a diameter greater than 6 mm. The primary and secondary curves as well as beveled edge configurations are built into the lens for the purpose of aiding on the lens centration and comfort. Adding color enhancement to the surface of the lens modifies the clear version of the Horizon 59 Oasis (hioxifilcon A) contact lens. The tinting process alters or changes the lens by affixing a listed color reactive additive on that portion of the anterior (front) surface of the lens that corresponds to the irris. The color additives are used in the amounts not to exceed the minimum reasonably required to accomplish the intended coloring effect. The practitioner may also choose tint intensity and custom mix colors. The Horizon 59 Oasis (hioxifilcon A) lenses are available in shades of the following: blue, green, brown and aqua. Combining one or more reactive colors additives with distilled water forms the color enhancement. The reactive color additives that may be used either alone or in combination are: Reactive Blue 19, Reactive Black 5, Reactive Red 11, Reactive Orange 78, Reactive Yellow 15, Reactive Red 180.

W-55 (methafilcon A) clear or tinted lens blanks are a hydrophilic polymer of 2hydroxyethy methacrylate crossed linked with ethyleneglycol dimethacrylate. The lens consists of 45% methafilcon and 55% water by weight when immersed in buffered saline solution. When the lens blank is tinted blue, up to .8 % of the color additive Copper Phthalocyanine Blue Pigment will be added to the MA. The color additive conforms to 21 CFR Part 74.3045. The soft contact lenses that are manufactured from W-55 lens blanks, clear or tinted, can be lathe cut into a hemispherical shell which are designed to fit over the corneal surface of the eye. These lenses are designed with varying base curves which conform to the shape of the radius of the cornea and center over the apex of the cornea to provide corrective myopia (nearsightedness), hyperopia (farsightedness), and astigmatism (multifocal).
