Abstract
The invention relates to a cornea contact lens, especially relating to a new soft cornea contact lens for controlling the myopia development. A whole lens is included. An external surface of the whole lens is provided with an annular convex region and/or an annual concave region. In the invention, the region out of the optical region at the external surface of the soft cornea contact lens is made to the state with smaller or larger curvature than that of the optical region, therefore, the light entering into the eyes from the part is focused on the retina, not the region after or behind the retina, thereby solving the defocusing state of the retina imaging at the periphery part of the macula lutea.
Description
Technical field
The present invention relates to a kind of contact lens, relate in particular to a kind of novel soft corneal contact lens of controlling myopia progression.
Background technology
At present studies show that at near-sighted occurring principle the out-of-focus appearance of human eye retina's macula lutea periphery causes the growth of axis oculi.Therefore,, can control the growth of axis oculi if can allow the imaging at this position not be out-of-focus appearance, thus the development of control myopia.
Present various appliances can only image in the macula lutea position, and the macula retinae periphery are in out-of-focus appearance, have brought out the myopia progression of youngsters and children.The present invention can allow object image-forming on the retina of macula lutea periphery, thereby has influenced the development of axis oculi, has intervened near-sighted development.Soft corneal contact lens on the market just is used for beauty treatment or is used for correction of refractive errors merely at present.Because its optical zone is sphere or aspheric, it is imaged on the retina, except macular area be imaged on the retina, the imaging of macula lutea periphery is for out-of-focus appearance.
Summary of the invention
The invention reside in the defective that overcomes prior art, a kind of novel soft corneal contact lens is provided.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of novel soft corneal contact lens comprises whole eyeglass, and the outside surface of described whole eyeglass is provided with the projection of annular or/and the recessed district of annular.
As preferably, the projection of described annular is or/and the inner edge in the recessed district of annular is 0.5-3.0mm apart from the distance at optical region center, and outer rim is 2.0-7.5mm apart from the distance at optical region center, and the diameter of described whole eyeglass is from 11mm to 15mm.
As preferably, the curved surface in described projection or recessed district is a sphere.
Outside the optical region of the outside surface at soft corneal contact lens of the present invention, make the state littler or bigger than the curvature of optical region, enter light focusing in the eyes thereby allow on retina from this part, rather than focus on before the retina or after, thereby solve the out-of-focus appearance of macula lutea peripheral retina imaging.
Description of drawings
Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of instructions, is used from explanation the present invention with embodiments of the invention one, is not construed as limiting the invention.In the accompanying drawings:

Mark is as follows among the figure: 1-puts in order eyeglass, 2-projection, the recessed district of 3-, 4-optical region.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
Shown in Fig. 1,3, a kind of novel soft corneal contact lens comprises whole eyeglass 1, described whole eyeglass 1 is provided with the projection 2 of annular, inner edge is 0.5-3.0mm apart from the distance at optical region center, and outer rim is 2.0-7.5mm apart from the distance at optical region center, and described protruding 2 curved surface is a sphere.
As shown in Figure 2, a kind of novel soft corneal contact lens comprises whole eyeglass 1, and described whole eyeglass 1 is provided with the recessed district 3 of annular.Described recessed district 3 inner edges are 0.5-3.0mm apart from the distance at optical region center, and outer rim is 2.0-7.5mm apart from the distance at optical region center, and the curved surface in described recessed district 3 is a sphere.
It should be noted that at last: the above only is the explanation embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; within the spirit and principles in the present invention all; any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
