Description

Medical myopia goggles lens connecting device for adjusting degree and interpupillary distance

Technical Field

The utility model relates to the technical field of medical goggles, in particular to a lens connecting device of a medical myopia goggle, which is used for adjusting the degree and the interpupillary distance.

Background

The eye is a delicate optical system. When external light is just focused on the retina, a clear image can be formed, and people can subjectively generate clear vision. When the external light is focused outside the retina, a blurred image is formed on the retina, and a person subjectively has blurred vision. Wherein, the eye focuses the external light before the retina, which indicates that the eye has too strong light-gathering ability and is called myopia. Conversely, if the eye focuses ambient light behind the retina, this indicates that the eye has insufficient light gathering power, known as hyperopia.

The myopia goggles are used for correcting vision and clearly seeing objects at far distance. In order to maintain a certain accommodation of the ciliary muscle of the eyeball. The distance light cannot be focused on the retina, so that the distance object is unclear, and a clear object image can be obtained after the myopia glasses are worn, so that the vision can be corrected.

The myopia goggles have certain prevention effect on complications caused by high myopia, such as retinal detachment, vitreous opacity, cataract, glaucoma, nystagmus and the like.

The myopic eyewear is a concave lens. 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 myopia is mainly characterized in that light rays are gathered in front of the retina prematurely due to the deformation of crystalline lenses, the concave lens plays a role of dispersing the light rays, and the concave lens forms an upright and reduced virtual image, so that the image distance is lengthened and the image distance just falls on the retina.

At present, the medical myopia goggles lens connecting device for adjusting the degree and the pupil distance is provided for solving the problems that the degree and the pupil distance cannot be effectively adjusted according to myopia of different degrees, the size is large and the problem of storage is not easy to occur.
