## Abstract

The present disclosure is directed generally to a lens that provides a stop signal to a myopic eye, over a substantial portion of the spectacle lens that the viewer is using. The present disclosure is directed to devices, methods and/or systems of imposing a stop signal to eye growth, using a spectacle lens in conjunction with a micro lenslet array. The present disclosure is also directed to devices, methods and/or systems of modifying incoming light through spectacle lenses that utilizes chromatic cues to decelerate the rate of myopia progression. The present disclosure is directed to devices, methods and/or systems of imposing a stop signal to eye growth, using a spectacle lens in conjunction with a refractive optical element and/or diffractive optical element that offer conflicting or contradictory optical signals at a wavelength between 510 nm and 610 nm.

## Claims

### Claim 1

An ophthalmic lens for a myopic eye comprising: a base lens with a focal power to correct, at least in part, the refractive error of the eye; and at least one micro lenslet array comprising at least one micro lenslet; wherein the at least one micro lenslet array introduces a conflicting optical signal at a wavelength between 510 nm and 610 nm.

### Claim 2 (depends on 1)
