Embodiment 1
[0024] Embodiment 1: A progressive ophthalmic lens for adults with a microstructure, one of the two surfaces is a progressive surface, and the other is a non-progressive surface, and the first refraction area formed between the two surfaces is used to correct the refraction of the eye Not correct, a plurality of circular sub-regions 4 are set on the non-progressive surface to form a second refractive region. The sub-regions provide different refractive powers and have the ability to focus the image on a position other than the retina of the eye to suppress the refraction of the eye A function of unhealthy development.
[0025] See attached figure 1 As shown, a circular first clear vision zone 1 with a diameter of 8 to 12 mm is set centered on the center of the far zone, and a circular second clear zone 2 with a diameter of 6 to 8 mm is set around the center of the near zone. Connecting the first clear vision zone and the second clear vision zone, a long transitional clear vis...

The invention discloses an adult progressive spectacle lens with a microstructure; one of two surfaces is a progressive surface, the other is a non-progressive surface, and the non-progressive surface comprises a first refractive area and a second refractive area; the first refractive area has a first refractive power based on correction of refractive error of an eye; and the second refractive area has a refractive power different from the first refractive power, has a function of focusing an image at a position except the retina of the eye to suppress the development of refractive error of the eye, and is characterized in that: the second refractive area is configured from a plurality of circular sub-areas distributed on a non-progressive surface, the secondary area is not distributed in a bright vision area, and the bright vision area is composed of a first bright vision area with the center of a far-use area as the center, a second bright vision area with the center of a near-use area as the center and a transition bright vision area connected with the first bright vision area and the second bright vision area. According to the invention, the function of inhibiting myopia development is applied to the progressive spectacle lens, and the use comfort of a wearer is ensured.
Description
technical field [0001] The invention relates to a spectacle lens, in particular to a progressive spectacle lens, especially a progressive spectacle lens provided with a microstructure and suitable for adults. Background technique [0002] The human eye plays a vital role in obtaining human information. According to statistics, more than 80% of human information acquisition comes from the eye. At present, social life is full of various electronic screens, which emit light of different intensities, and the human eye is used more and more every day, resulting in continuous refractive error of the human eye, and this refractive error Growth is not accelerating. According to incomplete statistics, more than 80% of college students have refractive errors of more than 200 degrees. [0003] On the basis of refractive correction, there have been functional spectacle lenses that can suppress the refractive error of the human eye. For example, a concentric Fresnel multi-focal lens i...
