example 1

[0031] Example 1: preparation of transparent master ink composition

[0032] The binding polymer used 96 g of 1-dodecanethiol ("DODT"), 56.54 g of lauryl methacrylate ("LMA"), 7.40 g of methacrylic acid ("MAA"), 1367 g of methyl Hydroxyethyl acrylate ("HEMA"), 68.5 g of glycerin, 378 g of 1-ethoxy-2-propanol ("EP"), 1511 g of isopropyl lactate ("IPL"), and 8.89 g of 2, 2'-Azobis(2-methylbutyronitrile) ("AMBN"). DODT, monomer and solvent (except for about 50-100 cc of IPL) were first mixed in a 5 liter blue cap bottle and stirred for 10 minutes. The mixture was then poured into a 5 L stainless steel reactor with stirrer and nitrogen. The mixture was stirred and heated for about 25 minutes until the temperature was 68°C. After the temperature stabilized at 68 °C, AMBN was dissolved in the remaining IPL and added while turning on the nitrogen vent. Polymerization was allowed to proceed for 16-24 hours after which time the temperature was increased to 80°C and the reaction w...

[0033] Example 2: Preparation of black ink

[0034] By weighing 243.47g of 1D Black Define (made of 11.76% by weight of black iron oxide pigment (FeO.Fe 2 o 3 , CAS No. 12227-89-3) constituted) was added to a 400mL glass jar to prepare a black pad printing ink. 6% by weight of 1-propanol was also added to the jar. Place the jar under a stirrer and stir at 1800 rpm until the ink is uniform in appearance.

example 3

[0035] Example 3: Preparation of white ink

[0036] By weighing 49.98g of the original white pigment (primary white) (made of 30.00% by weight of titanium dioxide pigment (TiO2) in the transparent mother ink as described in Example 1 2 , CAS No. 13463-67-7)) was added to a 250mL glass jar to prepare a white pad printing ink. 100.00 g of clear master ink (described in Example 1) and 6% by weight of 1-propanol were also added to the jar. Place the jar under a stirrer and stir at 1800 rpm until the ink is uniform in appearance.

[0037] Starting from the inks described herein, colored lenses are prepared using methods and apparatus known in the art. These include, for example, the methods described in US Patent Publication 20090244479, which is incorporated herein by reference.

Abstract

Contact lenses have patterns in which the portion that substantially lies over the sclera when worn on-eye is brightly colored or tinted; the colored or tinted contact lenses can have colored or tinted central portions that enhance the iris when worn on-eye and limbal rings that enhance the limbus.

Description

Background technique [0001] Contact lenses can be tinted or tinted to provide various effects to the appearance of the eye. This can be used to correct cosmetic problems of the eye or for cosmetic purposes. U.S. Patent No. 4,652,099 proposes a contact lens having a peripheral portion that is stained white. However, simply painting that portion of the lens white will generally not result in a lens with a natural or desired eye appearance. The lenses of the present invention solve this problem. Contents of the invention [0002] The present invention is a contact lens having a central portion and a peripheral portion disposed around the central portion. The peripheral portion is tinted in a bright color with a pattern that gradually becomes transparent towards the outer diameter of the lens. [0003] The brightly stained peripheral portion may be opaque, semi-opaque, or translucent near the inner diameter of the peripheral portion, and may include a pattern of limbus or li...
