Colored pattern can deposit on the iris portion of eyeglass in any way.Preferable methods is offset printing pad (offset pad) print process that describes in detail a little with following at present.
Prepare a plate (not shown), this plate has the depression that is equivalent to desirable speckle patterns of flat surface and circle.In order to form Fig. 2, the pattern shown in 3 and 4, each depression all should have the degree of depth of diameter and the about 0.013mm of about 0.1mm.Each depression is configured to an annular shape, and this annular shape is corresponding to the shape of eyeglass iris portion.
Plate can be with the known technology manufacturing that is used to make integrated form analog or digital circuit.At first prepare a pattern more about 20 times than desirable pattern.Then with known camera technique this pattern is narrowed down to the pattern of accurate desired size, the part to be colored of this pattern is darker than all the other zones.Flat surface covers with photoresistance (photo resist) material, and this photoresist becomes water-fast in being exposed to light the time.The photoresistance pattern part is removed by washing with water, and the plate that obtains is etched into the desired degree of depth.Then the remainder photoresist is removed with mechanical means.
Colorant comprises a kind of pigment and is used for the bonding agent or the carrier of this pigment, and colorant deposition on the surface of plate, and is striden the pattern scraping with doctor blade.This makes printing ink fill up depression, and removes excessive printing ink from flat surface simultaneously.Colorant can more or less be opaque, decides on desirable change color degree.Opacity can be by the rate variable of pigment and bonding agent in the change colorant.Should be appreciated that, can obtain desirable effect with the opaque colorant of a kind of height or with having the major part of lacking opaque colorant slightly and covering the iris portion surface.
The pad of silicon rubber system is pushed down pattern remove removal ink from depression, this silicone rubber pad has soaked clearly silicone oil so that separate easily.Allow the printing ink on the pad driedly slightly paste the front surface of contact lenses then, printing ink is deposited on the iris portion with desirable pattern so that improve thickness.Certainly, silicone rubber pad must have enough flexible, so that adapt to the convex front surface of eyeglass.In order to reach more natural effect, print steps can repeat one or many with different colors with different patterns, because when checking on hand, finds to have many people's iris to contain more than one color.The pattern of printing needn't be definitely even, to strengthen the fine structure of iris.
Then the pattern of deposition is handled,, when being placed on eyeglass in the eye, will be run into a liquid so that can not separate when making it under being exposed to a liquid from eyeglass.Prevent that the correct method that separates from depending on the material of making the eyeglass pattern.Only that eyeglass is just passable at air drying or heating.For hydrophilic lens, can use United States Patent (USP) 3,679 at Wichterle, being used to described in 504 applies the technology (reference in the lump as a reference herein) of opaque pattern.
Be used to make a kind of method of preferred colored contact lens, generally comprise be added to three part colorants on the transparent contact lenses and make colorant anti-from eye liquid separation steps.The contact lenses that print will have the pupil part of non-opacity and center on the iris portion of above-mentioned pupil part with three part colorants.First's colorant, perhaps the outermost asterism has first tone, the second portion colorant, asterism promptly, be second tone, this second tone different third part colorant from first tone, or inboard asterism, be three color scheme, this three color scheme is different with second tone, and with first tone can be identical or can be inequality.
The outermost asterism is with such setting, so that the greatest member concentration of outermost asterism generally all is positioned on the outside of iris portion, but still in iris portion, and generally be positioned at the outside of outside asterism concentration of element, the greatest member concentration of the asterism in the outside will generally be positioned at the outside of inboard asterism greatest member concentration, although and the asterism in the outermost asterism and the outside is overlapping, first will distinguish outermost asterism and outside asterism with reference to uneven border; Although the asterism of the inboard in the outside is with overlapping, the uneven border of second reference will distinguish outside asterism and inboard asterism.Therefore, will provide a kind of eyeglass, it can change the human iris's who wears eyeglass apparent color, and gives very natural honey color outward appearance.
Be used for interrupted pattern is deposited on step on the lens surface, comprise first plate that has a depression with, these depressions are equivalent to first or outermost asterism, and with the colorant of first tone, preferably black fills up depression.Next step is that first flexible mat is being pasted first plate, and pushes down first flexible mat, makes its surface of pasting eyeglass (no matter which limit), thus the first of printing element.
Next step comprises second plate that has a depression with, and these depressions are equivalent to second portion or outside asterism, and with the colorant of second tone, the preferably filbert depression that fills up, this second tone is different from first tone.Next step comprises the surface (no matter being identical surface or opposite surfaces) that one second flexible mat is adjacent to second plate and pushes down eyeglass, thus printing second portion element.
Final step comprises with one the 3rd plate, the 3rd plate has the depression corresponding to third part or inboard asterism, and with the colorant of three color scheme, the preferably orange depression that fills up, this three color scheme is different with second tone, and with first tone or identical or different.This is by the surface (no matter which limit) that the 3rd flexible mat is adjacent to the 3rd plate and pushes down above-mentioned eyeglass, thereby printing third part element.Last eyeglass when putting on, makes wearer's iris present significant honey color.
Although top listed step to the each several part printing arrangement on the eyeglass order, this printing order has no importance for the present invention, and any other printing order is all included by the present invention.In addition, said method can comprise top minimum and maximum distance cited in alternative embodiment, forms inhomogeneous border.
The alternative embodiment that is used for printing different layers on the contact lenses iris portion is to utilize ink-jet (ink-jet) printing to replace the pad printing of each layer.Ink jet printing does not need to finish with pad or plate, and can implement under than the higher resolution of pad printing, thereby bigger details of each dyed layer and more natural final pattern are provided on the iris portion of contact lenses.
Adopt ink jet printing also to reduce and contact lenses or the device number that contacts with other device.For example, originally silicone rubber pad must contact with plate or base plate, contacts with contact lenses itself then.Contact between the each several part tends to the each several part that weares and teares, thereby needs to change the part of these wearing and tearing.In the ink jet printing process, in fact micro nozzle does not contact contact lenses, does not contact any other device yet.Thereby reduced the chance of micro nozzle abrasion.
In addition, ink-jet printer, can be easy to change to different color layers from a color layers so that by computer control with electronics method control.Therefore, in case determine a kind of multilayered invisible eyeglass design, and be divided into a plurality of color layers, then can each layer be added on the colored contact lens, thereby form a kind of colored contact lens that the apparent colour of wearer's iris can be changed over honey color with ink jet printing method.
As can be seen, the invention provides a kind of contact lenses that the outward appearance of iris color can be changed or is modified to significant honey color, the while can be estimated its fine structure and the outward appearance of nature is provided.Can carry out various changes to the function and the configuration of each several part; Illustrated in can replacing with equivalent device and those devices of explanation; And under the spirit and scope of the invention situation that does not break away from as described in the following claims, can utilize wherein some characteristic and irrelevant with other characteristics.
