Lenses, devices, methods and systems for refractive errors

Abstract

The present disclosure relates to lenses, devices, methods and / or systems for addressing refractive errors. Certain embodiments involve altering or controlling the wavefront of light entering the human eye. The lenses, devices, methods and / or systems can be used to correct, resolve, alleviate or treat refractive errors and provide excellent vision at distances covering distance to near without significant ghosting. Refractive errors may be caused, for example, by myopia, hyperopia or presbyopia with or without astigmatism. Certain disclosed embodiments of lenses, devices and / or methods include embodiments that address foveal and / or peripheral vision. Exemplary lenses in the field of certain embodiments include contact lenses, corneal onlays, corneal inlays and lenses for intraocular devices in the anterior and posterior chambers, accommodative intraocular lenses, electro-active spectacle lenses, and / or Refractive surgery.

Description

technical field [0001] Certain disclosed embodiments include lenses, devices and / or methods for altering or controlling the wavefront of light entering an eye, particularly a human eye. [0002] Certain disclosed embodiments relate to configurations of lenses, devices, methods and / or systems for correcting or treating refractive errors. [0003] Certain disclosed embodiments relate to configurations of lenses, devices, methods and / or systems for addressing refractive errors while providing excellent vision from far to near without significant ghosting. [0004] Certain disclosed embodiments include lenses, devices, and / or methods for correcting, treating, alleviating, and / or addressing refractive errors, particularly in the human eye. Refractive errors may be caused, for example, by nearsightedness or farsightedness with or without astigmatism. Refractive errors may be caused by presbyopia alone or in combination with nearsightedness or farsightedness with or without astigma...

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

[0018] 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
