Lenses, devices, methods and systems for refractive error

Abstract

The present disclosure is directed to lenses, devices, methods and / or systems for addressing refractive error. Certain embodiments are directed to changing or controlling the wavefront of the light entering a human eye. The lenses, devices, methods and / or systems can be used for correcting, addressing, mitigating or treating refractive errors and provide excellent vision at distances encompassingfar to near without significant ghosting. The refractive error may for example arise from myopia, hyperopia, or presbyopia with or without astigmatism. Certain disclosed embodiments of lenses, devicesand / or methods include embodiments that address foveal and / or peripheral vision. Exemplary of lenses in the fields of certain embodiments include contact lenses, corneal onlays, corneal inlays, and lenses for intraocular devices both anterior and posterior chamber, accommodating intraocular lenses, electro-active spectacle lenses and / or refractive surgery.

AI Technical Summary

Problems solved by technology

However, masking results in a loss of light entering the eye, which is an undesirable quality since it at least degrades the contrast of the image projected on the retina

Furthermore, these features are difficult to build on lenses such as contact lenses and / or intraocular lenses

[0019] Some problems with existing lenses, devices, methods and / or systems are, for example, that they attempt to correct refractive errors but compromise the quality of vision at different distances, and / or introduce ghosting and / or distortion
