Summary: The variable brightness of the night sky affects plants, animals, and humans, but knowledge about this variability is still insufficient, especially regarding the influences of the moon, clouds, and artificial lighting. Long-term measurements are necessary to make accurate statements about these effects.

Summary: Spectral Filter Array cameras provide a fast and portable solution for spectral imaging. This study investigates texture classification methods applied directly to the raw image, and shows that the Convolutional Neural Network outperforms other methods in terms of classification performance. The study also demonstrates the model's ability to adapt and scale for different environmental conditions.

Summary: This study analyzed the interaction between spectral transmittance of old-aged subjects before and after cataract surgery and blue light-filtering intraocular lens implantation, and the spectral power distribution of common street lamps. The results showed improved visual performance after surgery and intraocular lens implantation, although the blue light-filter seemed to prevent the visual system from benefiting from lamps with greater emission at short wavelengths.

Summary: This experimental study confirmed that the presence of YAG pits in IOLs leads to a deterioration in image performance, with a reduction in the total intensity of transmitted light between 450 and 700 nm wavelength. The contrast is significantly reduced, and test targets showed worse results compared to unmodified counterparts. Further experiments should investigate the effect of YAG pits on diffractive IOLs.

Summary: This study examines the impact of filters and intraocular lenses (IOLs) on the vision and productivity of workers in workplaces with specific illumination conditions. Results show that using IOLs with yellow chromophore significantly reduces light transmission. However, the use of IOLs, with or without yellow chromophore, does not affect the protection levels of filters.

Summary: Spectral-domain resonances for cavities formed by two distributed Bragg reflectors were analyzed both theoretically and experimentally. The study demonstrated the sensitivity and figure of merit of the cavity, as well as its application as a spectral filter. The findings suggest that the DBR-based resonators offer advantages including normal incidence of light and narrow-spectral-width resonances.

Summary: By coding a convolutional neural network based on the spectral transmittance of a programmable optical filter, optical imaging can be seen as equivalent to the results of hyperspectral data postprocessed by the CNN. This enables simultaneous implementation of hyperspectral data acquisition and CNN postprocessing, leading to more intelligent, informative, and real-time optical detection and sensing in remote sensing applications.

Summary: In a study comparing monofocal, trifocal, and trifocal toric intraocular lenses, it was found that trifocal and trifocal toric IOLs did not have a significant additional impact on retinal measurements using spectral-domain OCT compared to monofocal IOLs. The study included measurements of macular thickness, macular volume, and retinal nerve fiber layer thickness before and after implantation of the lenses, with similar changes observed across all groups.

Summary: In this study, a linear variable optical filter (LVOF) in the visible spectral region was prepared by combining a multi-target magnetron sputtering coating method with a self-made one-dimensional displacement baffle sample stage. The performance of the LVOF was significantly improved through vacuum-annealing.

Summary: The study aimed to determine if the use of a blue light-filtering intraocular lens (IOL) could prevent the onset of wet age-related macular degeneration (AMD). However, results showed no significant correlation between the presence of a blue light filter in the IOL and the occurrence of wet AMD. Patients with non-blue light-filtering IOL were injected later with anti-VEGF compared to patients with blue light-filtering IOL, contradicting the potential clinical benefit of the blue light filter.

Summary: This article introduces a finite-time neural network adaptive dynamic surface control design for single-input single-output nonlinear systems. The control algorithm utilizes a novel nonlinear filter and finite-time Lyapunov stable theory to ensure tracking error convergence within a small neighborhood of origin in finite time. Simulation examples demonstrate the superiority and effectiveness of the proposed control algorithm.

Summary: This study assessed the main corneal response differences between normal and subclinical keratoconus using a Corvis(R) ST device. The results showed statistically significant differences in various corneal biomechanical parameters, indicating the potential usefulness of noncontact tonometry combined with discriminant function theory for detecting subclinical keratoconus.

Summary: This study aimed to investigate the relationship between clinical characteristics and differences in lipid peroxidation in the subretinal fluid (SRF) of rhegmatogenous retinal detachment patients. Results showed that malondialdehyde (MDA) and protein content in the SRF increased in patients with high myopia and more extended retinal detachment, suggesting the importance of oxidative imbalance in managing these cases.

Summary: The study assessed the spectral transmittance of different layers of the human cornea, finding that UV range had the lowest transmittance while visible and IR ranges were almost equal. Bowman's layer had the highest absorption, leading to the lowest transmittance due to the thickness of the stroma.

Summary: This study assessed the visual quality and stabilization of corneal edema patients after cataract surgery. The results showed that there was an improvement in visual acuity after surgery, but there were still visual quality losses related to corneal changes in the edema group. The control group had better contrast sensitivity at high spatial frequencies. Clinical refraction may improve visual quality, but in corneal edema patients, these losses are related to corneal changes and do not change after three months of surgery.

Summary: In this study, the evaluation of color vision mechanisms in young moderate smokers compared to non-smokers showed that smokers had higher total error scores and worse sensitivity values, with significant differences in the upper visual hemifield. The findings suggest that even young moderate smokers may experience sensitivity loss in the blue-yellow mechanism, particularly in regions of lower retinal ganglion cell density.
