High myopia correction lens

Abstract

The invention discloses a high myopia correction lens. The high myopia correction lens comprises a lens body and a base. The lens body comprises a first single lens with the positive focal power, a second lens set with the total focal power being positive, a third lens set with the total focal power being positive and a fourth single lens with the negative focal power which are sequentially arranged from the eye side. A first positive lens of the second lens set is a low-refraction-index high-dispersion lens, a second negative lens of the second lens set is a high-refraction-index low-dispersion lens, and the base is connected with the lens body through a supporting rod and used for adjusting the angle between the lens body and a human eye. By providing a close-range high-quality real image, the adjustment state and the adjustment-less state of a naked high myopia eyeball are fast switched, high myopia can be effectively corrected, and the high myopia correction lens is convenient and easy for people with myopia to operate.

Description

technical field [0001] The invention relates to the field of optical systems, in particular to a high myopia correction lens. Background technique [0002] Most patients with high myopia have a consensus: the eyes will be comfortable only when the eyes can see the object clearly. When the human eye feels that the object is basically seen clearly, the eyeball will relax and adjust as much as it can. The way to reduce myopia is to see the object clearly. However, the eyes will be tired after a long period of negative adjustment, so it is necessary to look at infinity. A state of no regulation to balance. Since patients with high myopia need to place objects within 10cm to see clearly, it is very inconvenient to operate during the alternate viewing process of near and far. [0003] Among the popular myopia correction instruments currently on the market, part of it is to simulate a process of the eyes watching distant objects and watching close objects.

Since patients with high myopia need to place objects within 10cm to see clearly, the operation is very inconvenient during the alternate viewing process of near and far

[0003] Among the popular myopia correction instruments currently on the market, part of it is to simulate a process of the eyes watching distant objects and watching close objects. During the process of the simulated object from infinity to the clear image point of myopia, in fact, the eyes really adjust only the very short time when the eyes can see the image point clearly, and the rest of the time is that the eyes cannot see the object clearly However, being in an unadjustable relaxed state cannot achieve its purpose. The present invention aims to simulate two points in the treatment process and alternate them quickly, so that the eyes will not be tired and the eyesight can be quickly restored.
