Problems solved by technology

If the eye 4 is in this adjustment state for a long time, the spasm of the ciliary muscle 42 may also stimulate the elongation of the eye axis, thereby causing the deepening of myopia

Embodiment Construction

[0013] Below in conjunction with accompanying drawing and two embodiments the present invention is described in detail:

[0014] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

[0015] refer to image 3 , the first embodiment of the present invention utilizes chromatic aberration to control myopia and has cosmetic contact lenses, comprising a central zone 1 with a fixed focus, a tinted and light-transmitting lens extending outward from the central zone 1 A peripheral area 2, and a color printing area 3 extending outward from the peripheral area 2.

[0016] The contact lens is made of a copolymer material formed by the reaction of 2-hydroxyethyl methacrylate (HydroxyEthylMethAcrylate, HEMA) and methacrylic acid (MethAcrylic Acid, MAA). The contact lens has a diopter of -3.00D, a diameter of 14.2mm, a lens base curve of 8.6mm and a center thickness of 0.08mm...

Abstract

The invention relates to a contact lens utilizing chromatic aberration to control myopia and having a beautifying effect, and the contact lens is suitable to be allocated in front of a patient's eye to correct abnormal ocular refraction of the patient. The contact lens has a central area with a focus falling on a retina macula central fovea and a peripheral area that is formed by extending the central area outward and is dyed and light-permeable. Specifically, when incident light penetrates the colored dyed peripheral area, the peripheral area only permits passing of the light with a wavelength band identical to that of the dyeing color, and penetrating light with different wavelengths has different refractive indices, so that the incident light can be controlled so as to focus on or in front of the retina, and eye axial length increase can be gradually controlled and slowed due to adaption of the patient's eye axial length to the peripheral area's imaging on or in front of the retina, thereby retarding abnormal ocular refraction of the patient.

Description

technical field [0001] The invention relates to an optical lens, in particular to a contact lens. Background technique [0002] Colored contact lenses can make the wearer's appearance highlight a specific sense of shape, so it has been deeply loved by the public. Common colored contact lenses mimic the natural appearance of the iris, with colorful shapes and lines radiating from the area to help the eye look more natural A reinforcement method that can make the appearance of the eyes different from the normal state. However, these colored contact lenses have so far focused on aesthetics, allowing wearers to have different iris edges to produce special effects on facial features. [0003] Such as figure 1 , which shows that when the eye 4 of a myopic patient is not wearing a myopic lens, the distant scene is imaged in front of the retina 41, figure 2 When the eye 4 of the myopia patient wears a myopia lens 5 , the distant scene is imaged on the retina 41 through the adju...
