background: silicon hydrogel bandage contact lenses are used to enhance epithelial healing, control surface-generated pain, and prevent epithelial erosions after refractive surgery. considering the importance of faster reepithelialization in preventing complications of photorefractive keratectomy (prk) and the fact that the features and specifications of these commercially-available lenses are ...

Photochromic Materials. In their Communication (e202214202), Lars Heinke et al. report nanoporous films with oriented arrays of molecular motors for light-controlled adsorption and diffusion.

The supramolecular design of photochromic molecules has produced various smart molecular assemblies that can switch their structures and/or functions in response to light stimuli. However, most of these assemblies require large structural changes of the photochromic molecules for an efficient conversion of assembled states, which often suppresses the photoreactivity within the self-assemblies. ...

Anabaena sensory rhodopsin (ASR) is an archaeal-type rhodopsin found in eubacteria. The gene encoding ASR forms a single operon with ASRT (ASR transducer) which is a 14 kDa soluble protein, suggesting that ASR functions as a photochromic sensor by activating the soluble transducer. This article reviews the detailed photoreaction processes of ASR, which were studied by low-temperature Fourier-tr...

The celebrated Lambert-Beer law of light absorption in photochromic media is only valid at low intensities of incident light and low concentration of chromophore. Here we address the generic problem of photoabsorption dynamics, experimentally studying the case of azobenzene isomerization. We show that the nonlinear regime is very common and easy to achieve in many practical situations, especial...

Several resorcin[4]arenes functionalized with two anthracene units on opposite sides of the upper rim of the macrocycle were synthesized. We investigated the potentially photochromic properties of these systems, with the main focus on the intramolecular [4+4] cycloaddition of the anthracenes and its reversibility by thermal ring opening. Whereas compound 9 proved to be a switchable host system ...

Purpose: To evaluate visual function in patients with different types of light-filtering intraocular lenses (IOLs) Methods: In this prospective comparative clinical study Cataract patients with different types of IOLs in Khatam-al-Anbia Eye Hospital, Mashhad were enrolled and followed for three months postoperatively. Corrected distance visual acuity (CDVA), color discrimination under photopic ...
