Embodiment Construction

[0056] refer to Figure 1A and 1B , the ophthalmic lens 100 includes two regions that can be switched between different optical states independently of each other. Specifically, the lens 100 includes an on-axis region 102 (i.e., the optical axis of the lens 100 intersects the region 102) and a peripheral region 104 surrounding the on-axis region 102, each of which can partially scatter incident light in the state and the region. Toggle between another state for the region to be transparent. The lens 100 has a multilayer structure consisting of electro-optical cells laminated between two layers 110a and 110b having optical power. The electro-optic cell consists of a layer 124 of electro-optic material sandwiched between two opposing transparent substrates 108a and 108b. Transparent electrode layers 106a and 106b are disposed on facing surfaces of substrates 108a and 108b, respectively, adjacent to the electro-optical material.

[0057] The top lens layer 110a is a plano-conv...

Abstract

An ophthalmic lens includes a first region corresponding to a first area of an optical surface of the ophthalmic lens and a second region corresponding to a second area of the optical surface of the ophthalmic lens different from the first area. The second region has an optically-switchable component switchable between a first optical state and a second optical state different from the first optical state. In the first optical state, the second region partially scatters or defocuses light incident on the second area.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Provisional Application No. 62 / 837,688, filed April 23, 2019, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to ophthalmic lenses having dynamic optical properties, and more particularly, to ophthalmic lenses having dynamic optical properties for reducing the progression of myopia. Background technique [0004] The eye is an optical sensor in which light from an external source is focused through the lens onto the surface of the retina, an array of wavelength-dependent photosensors. Each of the various shapes that the lens of the eye can take is associated with a focal length at which rays of external light are optimally or nearly optimally focused to produce an inverted image on the surface of the retina that corresponds to the external image observed by the eye. In each of the various shapes that the lens ...
