Problems solved by technology

However, these methods have some significant defects
For example, the clarity of the visual image obtained by the normal eye cannot be quantitatively controlled, and the use of goggles to cover the amblyopic eye will have a negative impact on the psychology of amblyopic children, and long-term use of drugs will have side effects, etc.
[0005] In addition, although both masking and suppression are effective in reducing the clarity of visual images obtained by the normal eye, this reduction cannot be quantitatively controlled

Abstract

The invention discloses a lens production method, which comprises the following steps: obtaining the shape information of a refraction structure layer and the texture structure shape information of a three-dimensional refraction structure; selecting a positional relationship between the three-dimensional refraction structure and a substrate layer, and selecting a positional relationship between the refraction structure layer and a filter structure layer; determining production materials for the refraction structure layer, the substrate layer and the three-dimensional refraction structure according to the positional relationship between the three-dimensional refraction structure and the substrate layer and the positional relationship between the refraction structure layer and the filter structure layer; producing a lens according to the obtained shape information of the refraction structure layer, the texture structure shape information of the three-dimensional refraction structure, the positional relationship between the three-dimensional refraction structure and the substrate layer, the positional relationship between the refraction structure layer and the filter structure layer, the production material for the refraction structure layer, the production material for the substrate layer and the production material for the three-dimensional refraction structure. According to the lens production method, information about spatial light passing through the lens can be quantitatively controlled.

Description

technical field [0001] The invention relates to the technical field of vision correction, in particular to a method for manufacturing a lens. Background technique [0002] Human visual impairment can be caused by many reasons, such as eye refractive problems such as myopia, eye or brain trauma, and neurological ophthalmic diseases such as amblyopia. The impairment of these visual functions will seriously affect the patient's study, work and life, and reduce the quality of life of the patient. [0003] In the treatment of visual dysfunction diseases caused by neurological factors (such as insufficiency, disorder or abnormality of the visual nervous system), it is often necessary to consider abnormal interactions between the eyes, such as amblyopia. Amblyopia is divided into monocular amblyopia and binocular amblyopia. People with monocular amblyopia have normal vision in one eye and subnormal vision in the other eye; people with binocular amblyopia have subnormal vision in ...
