Abstract
The invention provides a lens of a contact lens and a contact lens related thereto. A lens body of the lens of the contact lens comprises an optical area center, an optical area, optical area edges, a periphery and peripheral edges, wherein the peripheral edges are not on the same plane, so that the lens of the contact lens has an unfixable, irregular and random shape. For the contact lens using the lens, the shapes of the two lenses are different, and according to different shapes of the two lenses, the lens can be quickly and conveniently differentiated to be used for the left eye or right eye.
Description
Technical field
The present invention relates to be used for the contact lenses of eye, particularly a kind of have a contact lens unfixed, random, face shaping at random.Adopt the contact lenses of this contact lens, can be according to the face shaping of eyeglass, distinguishing eyeglass is to use for left eye or right eye.
Background technology
For a long time, the traditional design of secondary contact lenses is: the peripheral edge place of eyeglass at grade, the face shaping of two eyeglasses not there are differences.When the patient used contact lenses, can't directly distinguish eyeglass with the face shaping of eyeglass self was to use for left eye or right eye.When the contact lens of being worn when patient left and right sides eyes is different diopter, just need with the eyes eyeglass strictly by about order make a distinction.Conventional and/or known method is: helping memory, distinguish eyeglass by the sign on the mirror case of depositing contact lens is to use for left eye or right eye.Therefore the points for attention back warp regular meeting that wears contact lenses occurs as " after taking eyeglass, the right and left eyes eyeglass is distinguished in strictness, puts into left and right sides mirror case respectively and soaks eyeglass plucking." or " please not want and open two lids simultaneously, in order to avoid lid is exchanged." wait and point out statement.
Be to avoid said method to distinguish the inconvenience that left and right sides contact lens is brought, also have some company to put on mark about differentiation on the surface of contact lens by technologies such as engraving or laser-induced thermal etchings.But in the eyeglass manufacture process, often need to increase operation, destruction lens surface etc. and produce problems.
Summary of the invention
To distinguish the inconvenience of left and right sides contact lens and directly put on the problem that left and right sides mark is produced in order to overcome, the invention provides a kind of contact lens and relevant a kind of contact lenses on the contact lens surface by mirror case.This contact lenses can be according to the face shaping of eyeglass, and distinguishing eyeglass is to use for left eye or right eye.
The mirror body of contact lens of the present invention comprises optical region center, optical region, optical region edge, periphery and peripheral edge.Place on its peripheral edge or many places are not at grade, make the periphery of contact lens mirror body have face shaping unfixed, random, at random, thereby make contact lens have face shaping unfixed, random, at random, with the face shaping formation difference of routine and/or known contact lens.
Contact lenses of the present invention are for adopting the contact lenses of contact lens of the present invention, and the face shaping of two eyeglass there are differences, and according to two face shapings that eyeglass is different, just can distinguish eyeglass easily and fast is to use for left eye or right eye.

Wherein Fig. 1-1 is the front elevation (front view (FV)) in the three-view diagram.
Wherein Fig. 1-2 is the side view (outboard profile) in the three-view diagram.
Wherein Fig. 1-3 is the vertical view (planimetric map) in the three-view diagram.
Fig. 2-1, Fig. 2-2, Fig. 2-3 are the three-view diagram of another embodiment of contact lens of the present invention.
Wherein Fig. 2-1 is the front elevation (front view (FV)) in the three-view diagram.
Wherein Fig. 2-2 is the side view (outboard profile) in the three-view diagram.
Wherein Fig. 2-3 is the vertical view (planimetric map) in the three-view diagram.
1. optical region centers among the figure, 2. optical region, 3. optical region edge, 4. periphery, 5. peripheral edge, the place on 61. peripheral edges (5) is at grade peripheral edge not, and the place on 62. peripheral edges (5) is at grade peripheral edge not.
Embodiment
Conventional and/or known soft contact lens sheet at present diameter is about 12 millimeters to 16 millimeters, and the requirement of its diameter is greater than the diameter of eyes cornea.Diameter conventional and/or known hard contact lens sheet is about 8 millimeters to 11 millimeters, and the requirement of its diameter is less than the diameter of eyes cornea.
Contact lens of the present invention is reference with the diameter data of above-mentioned routine and/or known contact lens, considers comfortableness, stability the when patient uses contact lens of the present invention and the convenience of wearing.When contact lens of the present invention is soft lens, its peripheral edge (is crossed a straight line at optical region center to the optical region central shaft, arbitrarily some distance of the each point to the optical region edge on the straight line all equates) be not more than 8 millimeters apart from maximum, minimum locating is not less than 6 millimeters.When contact lens of the present invention is rigid eyeglass, its peripheral edge (is crossed a straight line at optical region center to the optical region central shaft, arbitrarily some distance of the each point to the optical region edge on the straight line all equates) be not more than 5.5 millimeters apart from maximum, minimum locating is not less than 4 millimeters.
Contact lens of the present invention can utilize any suitable technology or technology or its to make up and make production.It is routine and/or known that many such technology or technology or its are combined in this area, as shaping by stock removal technology, moulding technology and the comprehensive forming technology of making as contact lens etc.
Contact lenses of the present invention, the face shaping of two eyeglass there are differences, and two kinds of combinations can be arranged.One, the contact lens that two eyeglasses of secondary contact lenses (all be soft lens or all be rigid eyeglass) all adopt face shaping of the present invention to there are differences mutually; Two eyeglasses of its two, one secondary contact lenses (all be soft lens or all be rigid eyeglass), an eyeglass adopts contact lens of the present invention, and another eyeglass adopts conventional and/or known contact lens.
As shown in the figure, Fig. 1-1, Fig. 1-2, Fig. 1-3 are the three-view diagram of contact lens one embodiment of the present invention.Not at grade the existence of peripheral edge (61) of a place on the peripheral edge among the figure (5), and make the face shaping of whole contact lens be different from face shaping conventional and/or known contact lens.
As shown in the figure, Fig. 2-1, Fig. 2-2, Fig. 2-3 are the three-view diagram of another embodiment of contact lens of the present invention.Not at grade the existence of peripheral edge (62) of a place on the peripheral edge among the figure (5), and make the face shaping of whole contact lens be different from face shaping conventional and/or known contact lens.
Although invention has been described with reference to specific embodiment, the invention is not restricted to this, and can implement with various forms within the scope of the claims.
