The invention relates to the technical field of eye degree correction devices, in particular to manual-automatic dual-mode zoom glasses.
Background
Due to bad eye habit, the myopia group in the crowd is continuously improved every year, especially the student group, and the eyes can not be well regulated due to long-time facing to a blackboard or reading and writing in a short distance, thereby causing the approximate eyes.
The main way to solve the problem at present is to wear myopia glasses, and the principle is that the out-of-focus image plane of distant objects can be more far back to the retina for imaging. However, when people wear near vision glasses to see near objects, the imaging focal plane of the near objects falls behind the retina to generate new defocus, in order to see the near objects, the brain and the retina adaptively adjust the eyeball, the eyeball is gradually and backwardly adjusted to be long, and then when the far objects are seen again, the image falls in front of the retina again, the image is unclear again, and the lens is required to be matched again, so that the lens is reciprocated, the improvement of the degree of the spectacles and the reduction of the vision of the eyes are accelerated, and the danger of eye diseases such as retinal detachment, glaucoma and retinopathy is increased for a wearer.
In view of the above, multifocal spectacles have been developed which have a plurality of focal points on the same lens, and a wearer performs zooming by corresponding different focal points through pupils, so as to improve visual effects. In addition, there is also provided a pair of glasses for zooming through overlapping of two convex lenses, which can achieve multiple zooming to adapt to different wearers, and the conventional lens driving mode generally adopts motor driving, so that the wearers can adjust the position between the two convex lenses by controlling the rotation of the motor, and further achieve zooming.
However, the conventional zoom lens has the following drawbacks:
the existing zoom lens has a single structure, and can not keep the focus at the same position all the time, so that the wearer can wear glasses for a long time to observe near and far objects, and eye fatigue can be generated;
the existing lens driving mode is mostly driven by a motor mechanism to realize zooming, and when the glasses lose power, the problem that the zooming cannot be used exists; so that the use of the glasses is greatly limited;
