PARIS — A multifocal IOL with an innovative design has shown promising results, with most patients reporting good outcomes, according to a clinician. Lentis Mplus IOL (Oculentis) has overcome ...

The design for the bilayer bifocal lens was inspired by the rapid development of multi-functional holographic devices. "Researchers have devised many methods to improve the information capacity of ...

The new design is much simpler and makes it easier and more efficient to adjust the intensities at the two focal points. To demonstrate this advantage, Fan’s team used their bifocal lens in two types ...

For children diagnosed with worsening myopia, bifocals might be a better choice than standard lenses for nearsightedness; researchers have found that the condition doesn’t seem to progress as ...

While traditional bifocals slowed myopia progression significantly ... An additional advantage of the executive design is that the entire lower portion of the lens has the positive power, thereby ...

Hence, our design concept can only be realized in a ... at the example of a plasmonic beam switching metasurface and a bifocal metalens. The method proposed has the benefit that it is highly ...

Bifocal contact lenses allow a person to see clearly both at a distance and up close by correcting near, intermediate, and distance vision. Anyone interested in trying bifocal contact lenses can ...
