MULTIFOCAL AND EDOF INTRAOCULAR LENSES IN 2020.
Ophthalmology (Rochester, Minn.), 2020Ophthalmic surgeons are being overwhelmed by the influx of multifocal intraocular lens options in recent years, with close to one hundred intraocular lenses currently on the market in 2020. This practical and technical update on a representative group of

We show that total, very well-behaved lenses are not very well-behaved when treated proof-relevantly in the setting of homotopy type theory/univalent foundations. In their place we propose something more well-behaved: higher lenses. Such a lens contains an equivalence between the lens's source type and the product of its view type and a remainder type,

A technique for accurately figuring very thin, lightweight lenses is discussed. The phase change required to focus a plane wave into a point is calculated and photographically plotted with exposure proportional to phase (scaled from 0 to 2pi). The plot is photoreduced and the photoreduction is etched, with the depth of etch approximately proportional ...

Ultraviolet-Absorbing Spectacle Lenses, Contact Lenses, and Intraocular Lenses
Optometry and Vision Science, 1990Optical materials that are available to the practitioner for protection of the eye against hazardous exposure to ultraviolet radiation (UVR) are discussed. Principles of protection, procedures for calculating safe ocular exposure duration, and transmittance curves of commonly prescribed spectacle lenses, contact lenses, and intraocular lenses are ...

X-ray focusing with efficient high-NA multilayer Laue lenses
Light: Science and Applications, 2017 Multilayer Laue lenses are volume diffraction elements for the efficient focusing of X-rays. With a new manufacturing technique that we introduced, it is possible to fabricate lenses of sufficiently high numerical aperture (NA) to achieve focal spot ...

Advanced LIGO and Advanced Virgo could observe the first lensed gravitational wave sources in the coming years, while the future Einstein Telescope could observe hundreds of lensed events. It is, therefore, crucial to develop methodologies to distinguish between lensed from unlensed gravitational-wave observations.

In classical aberration theory it is assumed that, in a centered system, each surface can be represented in even powers of the radial distance from the axis. When this is not the case, a modified aberration theory must be used.
