Imaging with two skew ideal lenses.

In lens systems, the constituent lenses usually share a common optical axis, or at least a common optical-axis direction, and such combinations of lenses are well understood. However, in recent proposals for lens-based transformation-optics devices [Opt. Express26, 17872 (2018)OPEXFF1094-408710.1364/OE.26.017872], the lenses do not share an optical-axis direction. To facilitate the understanding of such lens systems, we describe here combinations of two ideal lenses in any arbitrary arrangement as a single ...

Pigmented Contact Lenses for managing Ocular Disorders.

Blocking a selected wavelength range from the light spectrum can have multiple benefits. Ultra-violet (UV) radiation is detrimental to the retina, necessitating its blocking through sunglasses and contact lenses. The near-visible light also has enough energy to cause damage but, is typically not blocked by commercial lenses. Filtering light can also be useful to patients with migraines, amblyopia, and color blindness. Here, to achieve blocking, incorporation of pigments extracted from colored agro-products ...
