Technical Field

The embodiment of the utility model provides a relate to near-sighted lens technical field, concretely relates to near-sighted functional lens and have glasses of this near-sighted functional lens.

Background

The myopia glasses are glasses for correcting vision and making people clearly see objects far away, and aim at keeping certain accommodation capacity of ciliary muscle of eyeball. The myopia glasses have certain prevention effect on complications caused by high myopia, such as retinal detachment, vitreous opacity, cataract, glaucoma, nystagmus and the like. The spectacles for myopia are concave lenses. The image formed by a concave lens, which is mainly used to correct myopic eyes, is always smaller than the upright virtual image of an object. The degree of the glasses is as follows: the refractive power of an ophthalmic lens is generally expressed in degrees. One diopter (dioptore) equal to 100 degrees spoken by an average person or a spectacle store, i.e., D1.00 in non-chinese countries (where D is dioptore rather than "Degree). The more serious the vision problem, the deeper the required lens power and the higher the lens thickness. However, the myopia glasses only can achieve the purpose of enabling the myopia patients to see clearly, but cannot achieve the purpose of preventing the myopia patients from further seeing.
