Description

Technical Field

[0001] The utility model relates to the technical field of visual defect compensation glasses, in particular to a pair of clamping hemianopsia glasses. Background Art

[0002] Hemianops ia refers to the loss of visual field in half of the visual field. It includes homonymous hemianopsy and heteronymous hemianopsy. The loss of visual field in both eyes is on the right or left side, which is called homonymous hemianopsy. The loss of visual field in both eyes is called bitemporal hemianopsy, and the loss of visual field in both eyes is called bitonasal hemianopsy. The normal visual field of a person is 60 degrees to the left and right. Within this range, people can perceive objects, colors, light, etc., and can also deal with emergencies in crises. Therefore, normal vision is a necessary mechanism for people's daily life. Patients with visual field defects, accompanied by visual impairment, can be seen in refractive damage, and there is a missing piece of invisible in the entire visual field, which is common in fundus diseases, retinal damage, etc., which brings great inconvenience to daily life and work. The lack of part of the visual field also makes it impossible to make timely emergency response to dangerous moments, causing great harm.

[0003] The principle of the reflector is that light is reflected on the mirror surface. The mirror is an object with a smooth surface. When light is directly irradiated on the surface, all or most of it can be reflected along the reflection angle, thus forming an image. Light will reflect and refract at the interface between two media. The mirror surface is composed of a reflective coating, and the reflective coating is almost smooth, so it can form a mirror reflection. The reflection of light by the mirror obeys the law of reflection, and its reflection ability depends on the angle of the incident light, the smoothness of the mirror surface, and the properties of the metal film.

[0004] Currently, most glasses on the market are myopia glasses, reading glasses, hyperopia glasses, sunglasses, filters, etc., but these are worn by people with normal vision and cannot meet the needs of patients with hemianopsia. Some use membrane prisms attached to the lenses to also have the effect of hemianopsia, but the effect is limited and can only perform low-intensity correction, which cannot achieve the desired effect.

The above clamping design can be matched with any glasses, and the stability and reliability of the clamping type hemianopsia glasses can be effectively improved through the tight fit between the lens and the clamping member.

[0014] Furthermore, the bottom ends of the clamping legs are covered with silicone sleeves to avoid scratching the lenses.
