Description
Technical Field
The invention relates to the technical field of amblyopia treatment and ocular light, in particular to an ophthalmic lens for amblyopia treatment and a processing method thereof.
Background
Amblyopia is the prevalence of about 1-5% worldwide of vision where, during vision development, vision correction due to abnormal visual experience such as strabismus, refractive error, high refractive error, and form deprivation is best achieved for single or both eyes, which is lower than normal children's vision of the corresponding age, and the eye examination is free of organic lesions. Amblyopia is a disorder of vision nerve development, and the influence on visual function can be roughly divided into impairment of visual function of monocular and binocular eyes. The single eye vision function damage mainly comprises the best corrected vision decline, contrast sensitivity decline and the like, and the main characteristics of the double eye vision function damage are that the vision information of the weak vision eyes is restrained, including the damage of simultaneous vision, double eye fusion and stereoscopic vision.
Amblyopia is a disease that severely impairs both monocular and binocular vision. The current treatment modes for amblyopia mainly comprise refractive correction, covering, medicine or optical depression therapy, vision training and the like. Wherein the treatment of the obscuration of the non-amblyopia eye is a gold standard for the treatment of monocular amblyopia. However, more and more studies have found that the reconstruction of binocular vision plays an important role in the treatment of amblyopia. The non-fully covered compression treatment can maintain a certain binocular vision between the eyes. The suppression treatment includes pharmaceutical suppression or optical suppression. The optical depression is to treat the spectacle lens for eye care to blur the visual effect of eye care, reduce the visual acuity of eye care and the contrast sensitivity of medium and high spatial frequency, so that the amblyopia eye is stimulated by enough visual information.
The current common optical method is to use a pressing film to press and paste on the glasses lens so as to achieve the effect of quantitative fuzzy vision. The pressing film is a soft semitransparent plastic filtering sheet with different transparencies, quantitatively blocks light transmission in a grading mode and reduces visual acuity, is pressed on the glasses lenses of the eye care, and can balance the spatial contrast of the two eyes. The size of the hold-down film is about 2.5 "x 2.5", which can be cut and trimmed according to the size and shape of the frame, and then adhered to the eyeglass lenses with water (effect as shown in fig. 15). The inhibition amount of the inhibition film can be customized to be different grades of <0.1, 0.2, 0.3, 0.4, 0.6, 0.8, 1.0, etc.
The patent with publication number CN105139721B discloses a vision function testing method based on shielding glasses, which is characterized by comprising the following steps: 1) Manufacturing a corresponding optical filter assembly; 2) Selecting a corresponding shielding film, wherein the shielding film is a amblyopia inhibition film with a certain vision grade; 3) Selecting a spectacle frame and determining a specific size of a lens inlay area of the spectacle frame; 4) Cutting the size of the optical filter component to be matched with the lens embedding area, and cutting the size of the amblyopia pressing film to be consistent with the size of the cut optical filter component; 5) The two optical filter components are respectively embedded and fixed in the lens embedding area, and the smooth surface of each amblyopia pressing film and the inner surface of the corresponding optical filter component are stuck into a whole to form shielding glasses; 6) The prepared shielding glasses are worn on eyes of healthy young volunteers, functional tests for simulating vision disorder states caused by age-related cataract are carried out on the healthy volunteers, and possible measures for improving the life ability of the aged of specific ages can be provided according to test results.
However, the patent has the following defects in the actual use process, the pressing and pressing film has the problems of high maintenance requirement, short service life, attractive appearance influence and the like, and the film layer edge is easy to warp and dust accumulation when used for a long time or maintained improperly, so that the adhesion degree is reduced, and the treatment effect and the patient compliance are influenced.
