The spherical and chromatic are the primary aberration type that degrades the performance
of optical instruments used in human eye vision correction. This paper demonstrates and …

In recent years, waveguide-based planar solar concentrator technology has garnered
increased attention within the Concentrated Photovoltaics (CPV) sector due to its compact …

The popular treatment of cloudy eye (cataracts) replaced the cloudy natural lens with an
artificial intraocular lens (IOL). The main factor that determines the performance of IOL is …

The manufacture of contact lenses is a highly accurate process that focuses on selecting
appropriate material prescribed by specialists to eliminate certain vision defects, such as …

Globally, many people suffer from refractive errors. Using the nanocomposite materials with
a high Abbe number (νd) and a high refractive index (RI) has made an excellent promise for …

This paper estimates a specific detailed diffractive aspheric bifocal intraocular lens (IOL)
used to correct and reduce corneal aberration and a patient's standard surgical implantation …

The popular treatment of cloudy eyes (cataracts) replaces the cloudy natural lens with an
artificial intraocular lens (IOL). The spherical and chromatic aberration are the main factors …

Correction of chromatic and spherical aberration using different hybrid multifocal intraocular
lenses (MIOLs) was investigated. In this study, hybrid multi-focal length MIOLs of different …

ABSTRACT Glasses with compositions [(50-X) TeO2 20 B2O3 30 ZnO x Dy2O3] where X= 0,
1, 2, 3, 4 and 5 mol% were synthesized by melt quenching method. X-ray diffraction (XRD) …
