Embodiment Construction

[0043] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0044] The embodiment of the present invention provides a light-adjustable lens, which is suitable for preparing glasses for treating amblyopia. Such as figure 1 As shown, the light-adjustable lens includes a light-adjustable functional layer 10 and a light-absorbing functional layer 20 that are stacked. Wherein, the dimming functional layer 10 includes a first substrate 110 and a second substrate 120 oppositely arranged, an...

Abstract

The invention provides a dimming lens and a preparation method thereof, and further provides dimming spectacles for treating amblyopia. The dimming lens comprises a dimming functional layer and a light absorption functional layer which are laminated; the dimming functional layer internally comprises a polymer dispersed liquid crystal layer, and can implement a transparent state and a non-transparent state under the action of an electric field; the light absorption functional layer comprises a light absorption part and a light transmission part; and the light absorption part internally containsa light absorption material and can absorb incident light. The lens can reduce light transmittance to light transmittance smaller than 3% when being used for shielding a healthy eye, and can fulfillthe aims of protecting a bad eye and exercising the bad eye when being used for the bad eye. Compared to a conventional amblyopia treatment tool, the treatment spectacles prepared from the lens are excellent in treatment effect and good in patient compliance.

Description

technical field [0001] The present invention relates to the field of optical technology, in particular, to a light-adjustable lens and a preparation method thereof, and also relates to the light-adjustable lens and light-adjustable glasses. Background technique [0002] Amblyopia is a relatively serious eye disease. For amblyopia patients with inconsistent degrees of amblyopia in both eyes, covering is the first choice for amblyopia treatment and plays an absolute role in the treatment of amblyopia. [0003] At present, the most common covering method is to cover the healthy eye (the eye with better vision), only give enough visual input to the poor eye (the eye with poor vision), and force the poor eye to fixate, in order to visually stimulate the poor eye in a short time. , so that it rapidly develops to the same vision as the healthy eye. [0004] Most of the covering methods use goggles to cover, which is low in comfort and aesthetics, resulting in poor patient complian...
