Ophthalmic systems are provided that include both a photochromic component and a blue-blocking component.

Photochromic ophthalmic systems that selectively filter specific blue light wavelengths

An electro-active optical cell is described including a layer of electro-active material, a front glass substrate member, and a back glass substrate member. The optical cell is capable of independently providing changeable optical power with the application of an electrical potential. The cell is also configured to be affixed to an external surface of a plastic substrate and to provide the changeable optical power, with at least one of the front substrate or the back substrate of the optical cell being an outermost optical layer. The layer of electro-active material may have a thickness less than 10 &#x3bc;m, and the glass substrate members may each have a thickness approximately between 20 &#x3bc;m and 500 &#x3bc;m.

Electro-active lenses including thin glass substrates

Embodiments of the present invention relate to a multifocal lens having a diffractive optical power region and a progressive optical power region. Embodiments of the present invention provide for the proper alignment and positioning of each of these regions, the amount of optical power provided by each of the regions, the optical design of the progressive optical power region, and the size and shape of each of the regions. The combination of these design parameters allows for an optical design having less unwanted astigmatism and distortion as well as both a wider channel width and a shorter channel length compared to conventional PALs. Embodiments of the present invention may also provide a new, inventive far-intermediate distance zone and may further provide for increased vertical stability of vision within a zone of the lens.

Multifocal lens having a progressive optical power region and a discontinuity

Embodiments described herein may provide an electro-active lens. The electro-active lens may comprise a first substrate, a second substrate, and an electro-active element disposed between the first substrate and the second substrate. The electro-active element may be configured to alter the optical power of at least a portion of the electro-active lens. The first substrate may comprise a different material than the second substrate.

Electronic lens comprised of hybrid materials

Aspects of the present invention provide multifocal lenses having one or more multifocal inserts comprising one or more diffractive regions. A diffractive region of a multifocal insert of the present invention can provide a constant optical power or can provide a progression of optical power, or any combination thereof. A multifocal insert of the present invention can be fabricated from any type of material and can be inserted into any type of bulk lens material. A diffractive region of a multifocal insert of the present invention can be positioned to be in optical communication with one or more optical regions of a host lens to provide a combined desired optical power in one or more vision zones. Index matching layers of the present invention can be used to reduce reflection losses at interfaces of the host lens and multifocal insert.

Refractive-diffractive multifocal lens

An ophthalmic lens is presented in which the lens includes a progressive addition region and a dynamic optic. The dynamic optic and the progressive addition region are in optical communication. The progressive addition region has an add power which is less than a user's near viewing distance add power. The dynamic optic, when activated, provides the additional needed optical power for the wearer to see clearly at a near distance. This combination leads to the unexpected result that not only does the wearer have the ability to see clearly at intermediate and near distances, but the level of unwanted astigmatism, distortion, and vision compromise are reduced significantly.

Static progressive surface region in optical communication with a dynamic optic

Embodiments of the present invention relate to a multifocal lens having a mostly spherical power region and a progressive optical power region. Embodiments of the present invention provide for the proper alignment and positioning of each of these regions, the amount of optical power provided by each of the regions, the optical design of the progressive optical power region, and the size and shape of each of the regions. The combination of these design parameters allows for an optical design having less unwanted astigmatism and distortion as well as both a wider channel width and a shorter channel length compared to conventional PALs. Embodiments of the present invention may also provide a new, inventive far-intermediate distance zone and may further provide for increased vertical stability of vision within a zone of the lens.

The present invention relates to ophthalmic systems comprising a selective light wavelength filter, wherein said selective filter provides improved contrast sensitivity.

High performance selective light wavelength filtering providing improved contrast sensitivity

Multifocal lens having a progressive optical power region and discontinuity

Aspects of the present invention provide multiple-layer (multi-layer) composite lenses comprising two or more materials and methods for making the same. A multi-layer composite lens of the present invention can use multiple surfaces (internal or external) to form optical elements that can contribute to a total desired add power. The multiple contributing optical elements can be aligned so as to be in optical communication to form multiple stable vision zones to enhance optical performance and the vision experience of the wearer. Distributing the total desired add power across multiple appropriately aligned optical elements that are in optical communication with one another can reduce the total distortion of the lens, minimize the number of optical discontinuities introduced, can reduce optical power jump as experienced by the wearer's eye when traversing any discontinuity, and can reduce the visibility of any introduced optical discontinuity as perceived by an observer looking at the wearer.
