The contact lenses of producing according to above-mentioned two patents that have mark have following shortcoming:
(1) mark can be known in conjunction with prior art all to lower recess, the formation of this mark be through radium-shine, etc. technology form, cost of goods manifactured is higher;
(2) reach the purpose of sign through the depression that produces certain depth; There is not color; Promptly in the process of using, need the people of a myopia on the circle of 14mm diameter, looking for like CN94192456.4 said mark or the width among the patent CN99115983.7 through bright, dark contrast formation observability be the mark of 300um; The mark of obviously mentioning in these two kinds of technical schemes is not to be suitable for the mark that supplies the user to observe, promptly can't reach difference images of left and right eyes and the technique effect that is easy to user's identification.
Summary of the invention
In order to overcome the deficiency that prior art exists, the purpose of the utility model is to provide a kind of contact lenses of distinguishing images of left and right eyes and being easy to identification.
For reaching above purpose; The utility model provides a kind of contact lenses; The core that comprises optical region, around the peripheral part of this core, the diameter of described core is greater than the diameter of pupil; The mark that at least one has color is set on the described peripheral part, covers on the iris of eyeball after described mark is worn.
The further improvement of the utility model is that described mark is printed on the described peripheral part through printing process.
The further improvement of the utility model is that described mark is printed on the described peripheral part through method for stamping.
The further improvement of the utility model is, the color of described mark is a kind of in brown, blueness or the green.
The further improvement of the utility model is that the width of described mark is 1.5mm to 2.4mm.
The further improvement of the utility model is, describedly is labeled as in spherical degree, the progressive number of degrees, the prism number of degrees, the angle that contracts, interpupillary distance, trade mark, the trade name one or more.
The beneficial effect of the utility model is:
(1) mark that at least one has color is set on described peripheral part; Personnel only need look for the mark with color on transparent eyeglass just can learn the content that oneself need be known, eyeglass can be reached let the user distinguish images of left and right eyes and the technique effect that is easy to user's identification.
(2) cover on the iris of eyeball after described mark is worn, when the mark that uses with the iris color similar color, mark and iris combine together wearing afterwards, can not cause the apparent difference of contact lenses.
