AI Technical Summary
Conventional lenses for correcting myopia cause unwanted visual side effects such as halos around images due to annular add power regions focusing light in front of the retina, and existing dual-focus lenses fail to effectively prevent or slow myopia progression without compromising image quality.
An ophthalmic lens design featuring a central region with increasing radial sagittal power and an annular region providing radial curvature add power, optimized to compensate for spherical aberration and reduce off-axis imaging, thereby eliminating halos and enhancing image quality.
The lens design effectively prevents or slows myopia progression while maintaining clear vision without halos, improving image quality by compensating for spherical aberration and ensuring consistent radial sagittal power across the lens.
