Objective: To evaluate contrast-color sensitivity (CCS) of central vision, contrast-frequency sensitivity (CFS) and dynamic visual acuity (DVA) in healthy people and patients with ischemic optic neuropathy (ION).
Material And Methods: The study was performed for 115 eyes with normal static visual acuity (1.0) in 111 healthy people; 25 patients (39 eyes) with acute anterior ION and 26 patients (26 eyes) with chronic ION. Assessment of static visual acuity and refraction as well as ophthalmoscopy of the eye fundus were performed.
Results And Conclusion: Based on the data analysis of CFS, DVA and photometry of CCS, the quantitative estimation of age-related changing in light sensitivity and changing sensitivity of ill and healthy eyes of patients with acute and chronic ION has been carried out. The differences between changing of these functional parameters are used for discussion of the role of age-related changes of visual system hemodynamics in decreasing of light sensitivity. The possibility of usig the data of light sensitivity decreasing in the early diagnostics of visual system ischemic impairment is discussed.

Piezoelectric polymer textiles offer distinct advantages in the fabrication of wearable nanogenerators (NGs). One effective strategy to enhance the output capacity of NGs is to modulate the piezoelectric performance of the textiles. This paper focuses on further improving the piezoelectric properties of nylon-11,11 textiles through post-drawing and annealing treatments.

Numerous studies have shown the potential effect of bioactive agents against weeds. In this study, we developed two binary formulations with nonanoic acid, citral, or thymoquinone as herbicides and evaluated their physicochemical properties. The presence of the bioactive compounds in the formulations was confirmed through FTIR spectroscopy.

Non-celiac gluten/wheat sensitivity (NCGWS) is a syndrome for which pathogenesis and management remain debated. It is described as a condition characterized by gastrointestinal and extra-intestinal symptoms rapidly occurring after gluten ingestion in subjects who have had celiac disease or wheat allergy excluded. To date, the diagnosis of NCGWS is challenging as no universally recognized biomarkers have been yet identified, nor has a predisposing genetic profile been described.

Single-Photon Avalanche Photodiodes (SPADs) are increasingly utilized in high-temperature-operated, high-performance Light Detection and Ranging (LiDAR) systems as well as in ultra-low-temperature-operated quantum science applications due to their high photon sensitivity and timing resolution. Consequently, the jitter value of SPADs at different temperatures plays a crucial role in LiDAR systems and Quantum Key Distribution (QKD) applications. However, limited studies have been conducted on this topic.

Pediatric macular disorders are a diverse group of inherited retinal diseases characterized by central vision loss due to dysfunction and degeneration of the macula, the region of the retina responsible for high-acuity vision. Common disorders in this category include Stargardt disease, Best vitelliform macular dystrophy, and X-linked retinoschisis. These conditions often manifest during childhood or adolescence, with symptoms such as progressive central vision loss, photophobia, and difficulty with fine visual tasks.
