In order to achieve the above objects and effects, the technical means and the configuration of the present invention will be described in detail with reference to the preferred embodiments of the present invention.

Referring to the first, second and third figures, the central optical zone 11 is formed at the center of the lens 1 for light to pass through to the central image area 211 (macular portion) of the retina 21 of the user's eye 2, and is centrally located. The periphery of the optical zone 11 is surrounded by the peripheral optical zone 12, and the lens 1 is formed with a filter zone 13 at a position of the peripheral optical zone 12, and the filter zone 13 is formed by combining a plurality of colors in a predetermined ratio and is filterable. The preset percentage passes through the wavelength of the visible light to cause the visible light to fall on the peripheral image area 212 around the central image area 211 of the retina 21 (the peripheral image area 212 surrounds the periphery of the macula), and the filter area 13 It has at least one colored ring 131.

The preferred embodiment of the lens 1 described above is the lens 1 of the contact lens, but in actual application, it may also be the lens 1 of the frame glasses.

Furthermore, the filter region 13 of the lens 1 is preferably directly formed on the outer surface of the lens 1. However, in practical applications, it may be formed at the middle of the inner and outer surfaces, or may be attached to the outer surface of the lens 1. a filter having a filter region 13 for filtering a visible light passing through a predetermined percentage by a filter having a filter region 13, and the filter having the filter region 13 is preferably attached to the filter The curvature and size of the filter having the filter region 13 on the outer surface of the lens 1 vary with the outer surface, but in practical applications, the filter with the filter region 13 is also attached to the lens 1 On the outer surface, but the size covers only the peripheral optical zone 12 of the lens 1. However, there are many types of the filter region 13 formed on the lens 1, and the basic structure and manufacturing method are in accordance with the application range. The differences are mostly different, and they can be implemented in different ways depending on the actual application and needs.

In addition, the filter region 13 of the lens 1 is preferably provided with a plurality of colored rings 131, and the plurality of colored rings 131 are surrounded by the concentric circle around the central optical zone 11, but in actual use, the filter region 13 The plurality of colored regions 132 of different colors may be formed by the upper and lower or left and right patterns, or the upper, lower, left and right forms respectively (as shown in the third figure). However, the shape and style of the filter region 13 are many. It is only necessary to form on the peripheral optical zone 12, so that any equivalent shape and style can be covered by the present invention, and should be included in the patent scope of the present invention, and is combined with Chen Ming.

However, the filter region 13 of the lens 1 is a wavelength for filtering a predetermined percentage through the visible light, and the preset percentage is between 1% and 100%, so that the light is imaged on the retina of the eyeball 21 The surrounding peripheral image area 212, and because the blue is the main contrast color of red, the filter area 13 can be blended with blue and at least one other color in a preset ratio, and the blue percentage of the preset is at least More than 50%, and at least one other color is less than 50% (eg, blue can be 85%, green is 15% or blue can be 80%, green is 10%, red is 10%, etc.), ie The filter region 13 can be used to filter out the visible light (wavelength between 570nm and 750nm) by 30%, so that the longer wavelength light (such as red light with a wavelength between 620nm and 750nm) reaches the retina of the eyeball 2. The intensity ratio of 21 is lowered, so that the image falling on the retina 21 is completely present in the central image area 211, but in the peripheral image area 212, the wavelength combination of the image changes according to the design.

Further, in the peripheral optical zone 12 of the lens 1, it is preferable to print the filter region 13 by means of ink, pigment, or the like by pad printing, but in practice When applied, it can also be printed by lithographic printing or special screen ultraviolet (UV) ink printing, or by dyeing or coating, but the manner in which the peripheral optical zone 12 processes the filter zone 13 A lot, here is a brief description for understanding.

However, the cells in the retina 21 of the eyeball 2 that have different spectral sensitivity (Spectral Sensitivity) are called cone cells, and the cone cells can be distinguished into short (S) and medium according to the peak wavelength of spectral sensitivity. (M) and long (L), the peak wavelength of short cone cells is between 420 and 440 nm, the peak wavelength is between 531 and 555 nm, and the long peak wavelength is between 564 and 588 nm. The light after the filter region 13 is formed at the position of the peripheral image region 212 on the retina 21, so if the color of the filter region 13 is such that the predetermined wavelength of the light passes between 420 and 440 nm, 531 to 555 nm or Between 564 and 588 nm, the cones at different positions can be stimulated by the preset wavelength of light, and then various cones can be stimulated to produce hormones, and the length of the axial length of the eyeball 2 can be suppressed by hormones. In order to achieve the effect of preventing the deepening of myopia.

(1) A central optical zone 11 is formed at the center of the lens 1 for light to pass through and is clearly imaged on the central image area 211 of the retina 21 of the user's eye 2, and the central optical zone 11 is surrounded by the peripheral optical zone 12, and then A filter zone 13 is formed at the position of the peripheral optical zone 12 by means of a printing machine to pass through the filter zone 13 to filter out the wavelength of the visible light passing through the visible light, thereby imaging the light onto the center of the retina 21 of the eyeball 2. At the position of the peripheral image area 212 of the different retinas 21 around the image area 211 (the macula), the cones at different positions receive different wavelengths. The stimulation of the intensity, in turn, effectively delays or prevents the increase in the length of the eye axis, thereby achieving the effect of correcting or controlling myopia.

(2) The wavelength of light passing through the filter region 13 can simultaneously stimulate various cones on the retina 21, and the hormone secretion of different cones can be induced by stimulating various cone cells to suppress the axial length of the eyeball 2.
