Title:
LENS AND LENS ADJUSTMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/040635
Kind Code:
A1
Abstract:
The present application relates to the technical field of optical devices, and provides a lens and a lens adjustment method. The lens comprises a first substrate, a second substrate, and a baffle. The first substrate and the second substrate are provided opposite to each other, and the first substrate and/or the second substrate are elastic thin film substrates. In addition, the baffle is disposed between the first substrate and the second substrate, and the baffle is disposed in a circle along edges of the first substrate and the second substrate. The baffle is connected to the first substrate and the second substrate, so that a closed liquid storage chamber is defined among the first substrate, the second substrate and the baffle, and the liquid storage chamber is filled with an optical liquid. By means of the lens provided by the present application, parameters of the first substrate change in a direction from the central region to the peripheral region, so that the focal power of the lens is gradually increased, and thus, the lens forms a progressive defocusing effect in the direction from the central region to the peripheral region.
