    摘要: Several devices for determining a distance of an object a user of an electro-active lens is looking at are presented. Once the distance is determined, the devices may alter the optical power of the electro-active lens to ensure that the object is correctly focused. Optical range finding is a possible means for carrying out this task. An active rangefinder may emit optical radiation from a transmitter directed at the object. The optical radiation may then be reflected off the object. The reflected optical radiation may then be received with an appropriate receiver. The received optical radiation may then be processed by appropriate circuitry to determine a distance to the object. A passive rangefinder works without a transmitter. Instead, an appropriate receiver receives ambient sources of light from the object. The received light may then be processed by appropriate circuitry to determine a distance to the object.

    摘要: A film suitable for use in an ophthalmic system is provided. The film may selectively inhibit blue light within the wavelength range of 400 nm to 460 nm to reduce phototoxic light to the eye while maintaining photopic vision, and may be color balanced to allow for the system into which the film is incorporated to be perceived as colorless to a viewer observing and/or using the system. The system may have a photopic and scotopic luminous transmission of 85% or more and a phototoxicity ratio of less than 80%. When used in an ophthalmic system or other system disposed between an observer's eye and a light source, the film may reduce the flux of blue light to the internal structures of the eye while reducing or minimizing dilation of the pupil.

    摘要: 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.

    摘要: 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.
