Definitions
- the Figure depicts a normal human eye, to show the non-uniformity of the color pattern formed by the iris.
- Another satisfactory, though less preferred, method is silk-screening, using conventional screen materials.
- the desired pattern is formed on the screen, by combining numerous very small openings in the screen.
- the colorant is forced through this pattern onto the lens using a wiper blade.
- Suitable lens materials are cellulosics, such as cellulose acetate butyrate, which like the hydroxyl-containing polymers, has a reactive bond or site with which a "reactive" dye (discussed below) can react.
- the hydroxyl-bearing polymers and copolymers are generally hydrophilic, that is, they absorb water and are worn as "soft" contact lenses in the hydrated state, though they are manufactured in the hard, unhydrated state. Lenses made of these materials can be tinted by the present invention in either the hard or hydrated state, although if they are hydrated they should be blotted lightly so that the aqueous solution in which they have been hydrated is not dripping or running off the surface of the lens.
- SUBSTITUTE SHEET Soft contact lenses are commercially available in the above polymers and copolymers.
- the copolymers are generally cross-linked with a minor amount less than 1 wt. % of a cross-linking agent such as divinyl benzene, 1,1,1-trimethylolpropane trimethacrylate, ethylene glycol dimethacrylate, ethylene bis (oxyethylene)dimethacrylate, ethylene dimethacrylate, or 2-ethyl-2-hydroxymethyl-l,3- propanediol trimethacrylate.
- a cross-linking agent such as divinyl benzene, 1,1,1-trimethylolpropane trimethacrylate, ethylene glycol dimethacrylate, ethylene bis (oxyethylene)dimethacrylate, ethylene dimethacrylate, or 2-ethyl-2-hydroxymethyl-l,3- propanediol trimethacrylate.
- the viscosity should be high enough so that if a layer of the colorant is deposited on a smooth plate which is inclined at a 45° angle, the colorant does not flow down the plate.
- the alginate can comprise 10-40 wt. % of the colorant.
- Optional preferred additives to the colorant include a color-penetration improving agent such as thiodiethylene glycol; and a hygroscopic agent such as urea.
- Colorants containing vat dyes or thermosetting dyes are formulated from water, thickener such as alginate, and an alkaline agent, with urea as an optional hygroscopic agent following the same criteria discussed above for reactive dyes.
- Sodium hydroxide and sodium hydrosulfite are preferred vat dye alkaline reagents.
- the amount of dye is not critical and can be adjusted in accordance with the intensity desired in the finished lens.
- the dye can comprise about 1-15 wt. % of the colorant, and usually about 5-10 wt. %.
- the pattern which the colorant has assumed on the lens can be inspected.
- An advantage of this invention is that if the pattern has a defect or is otherwise unsatisfactory for any reason, it can simply be washed off and the lens returned to be recolored.
- the preferred pattern on the contact lens is a ring of color, leaving the central region of the lens uncolored.
- the uncolored central area can be about 3.85 to about 4.20 millimeters in diameter, to equal the size of the wearer's pupillary opening.
- the colored area can have an outside diameter of about 9.60 to about 10.40 millimeters, to cover the wearer's iris. The portion of the lens outside the colored area remains clear.
- the figure depicts a normal human eye and indicates the non-uniformity of the pattern of color in the iris.
- the color of the general background areas 1 frequently differ slightly from the color that appears to be concentrated in filament-like areas 2 which radiate approximately radially from the pupil.
- flecks or highlights 3 can appear randomly in the iris as well.
- a pattern of this type can be readily reproduced by the process of this invention, by photographing a human eye and transforming the photographed image via conventional photoresist techniques into a detailed pattern in the etched plate of an indirect gravure, or onto the pad of a flexographic printer or a silk screen. Then, by successive applications of colorants containing dyes which have been selected and/or blended to match the desired colors for the various portions of the iris, the lens can be printed with a pattern which matches the actual patterns of the human iris.
- This invention can also be utilized to tint the entire surface of a contact or ophthalmic lens.
- functional coatings can be applied in the same manner such as photochromic and scratch-resistant compounds and ultraviolet absorbers.
