Abstract:

The subject of the study is the role of the visible spectrum of everyday lighting in causing myopia in adolescents. The aim is to investigate the effects of narrow spectral compositions of everyday light on eye growth, identify induced changes in morphology and mechanical properties of the sclera by a rapidly evolving biological model; and based on experimental data, to identify the possibility of preventing the development of myopia in children and adolescents. Methods. The work was conducted using Japanese quails. LEDs with narrow spectral ranges (blue (450 ± 25 nm), red (630 ± 50 nm) and yellow (560 ± 50 nm) were used as light sources. The sizes and morphological features of the structural elements of the eye along the optical axis were studied in the native state using high-resolution acoustic methods, and in vitro with light and electron microscopy. The mechanical properties of the sclera were studied using a standard tensile machine. The main results were obtained for the first time at a physiological level of illumination from birth to the age of fertility (45–65 days). The narrow spectrum induced changes in anteroposterior axis length (APA), especially in lens thickness, morphology and mechanical properties of the sclera, were revealed in laboratory animals (Japanese quails), as they matured. Experimental data confirm the formation of ametropia in the eyes, when the spectrum of daily lighting shifts towards blue or red light. Practical significance. The results of the study allow us to pay attention to the spectral characteristics of everyday lighting sources, including display devices, which significantly affect the formation of eye ametropia in ametropia in children and adolescents, and provide recommendations for its prevention.
