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 encompassing far 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, devices and/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.

Lenses, devices, methods and systems for refractive error

Certain embodiments are directed to lenses, devices and/or methods For example, a lens for an eye having an optical axis and an aberration profile along its optical axis, the aberration profile having a focal distance and including higher order aberrations having at least one of a primary spherical aberration component C(4,0) and a secondary spherical aberration component C(6,0) The aberration profile may provide, for a model eye with no aberrations and an on-axis length equal to the focal distance: (i) a peak, first retinal image quality (RIQ) within a through focus range that remains at or above a second RIQ over the through focus range that includes said focal distance, where the first RIQ is at least 035, the second RIQ is at least 01 and the through focus range is at least 18 Diopters; (ii) a RIQ of 03 with a through focus slope that improves in a direction of eye growth; and (iii) a RIQ of 03 with a through focus slope that degrades in a direction of eye growth The RIQ may be Visual Strehl Ratio or similar measured along the optical axis for at least one pupil diameter in the range 3 mm to 6 mm, over a spatial frequency range of 0 to 30 cycles/degree inclusive and at a wavelength selected from within the range 540 nm to 590 nm inclusive

Lenses, Devices, and Methods for Ocular Refractive Error

The invention concerns a transparent and polarizing viewing element ( 2 ) divided into several zones ( 2 a , 2 b ). At least one of the zones ( 2 a ) is associated with a light polarizing filter. The light passing through the optical surface is affected differently for two of said zones ( 2 a , 2 b ) depending on the polarizing direction of said light. The polarizing filter is obliquely oriented relative to a horizontal direction (H) in the operational position of the element ( 2; 5 ), with an angle between the filter orientation and said horizontal direction of 90 degrees and of 0 degree.

The invention relates to a method for producing a polarising ophthalmic lens adapted to the eye/head behaviour of the wearer thereof and to said lens. The inventive ophthalmic lens comprises several areas associated to differently oriented polarising filters. The size and position of at least certain areas are determined according to the lens wearer's eye/head behaviour.

A transparent and polarizing vision element (2) divided into several areas At least two of said areas are associated with a luminous polarization filter The light flowing through the element is allocated differently for two the areas according to a direction of polarization of the light At least one polarization filter is oriented vertically, and at least one polarization filter is oriented horizontally in relation to the usual position of the element

A method for printing a binary hologram on a manufactured product comprises the provision of a stamp with a pattern corresponding to the hologram (30). The product is initially coated with a metal layer. The stamp is inked with a masking solution (40) and pressed against the manufactured product (50). Then, the hologram print is obtained by selective etching of parts of the metal layer which are not masked (60). The method is adapted for printing holograms on optical lenses.
