Temporal organization of physiology is critical for human health. In the past, humans experienced predictable periods daily light and dark driven by solar day, which allowed entrainment intrinsic circadian rhythms to environmental light–dark cycles. Since adoption electric light, however, pervasive exposure nighttime lighting has blurred boundaries day night, making it more difficult synchronize biological processes. Many systems are under control, including sleep–wake behavior, hormone secretion, cellular function gene expression. Circadian disruption perturbs those processes associated with increasing incidence certain cancers, metabolic dysfunction mood disorders. This review focuses on role artificial at night in regulation, mechanisms through aberrant affects brain. Converging evidence suggests that alters brain regions involved emotion regulation. occurs direct neural input from clock or indirect effects, altered neuroplasticity, neurotransmission Recently, been recognized its health effects. summarizes linking mood.

Visual Fatigue Induced by Viewing a Tablet Computer with a High-resolution Display

Korean Journal of Ophthalmology, Год журнала: 2017, Номер 31(5), С. 388 - 388

Опубликована: Янв. 1, 2017

In the present study, visual discomfort induced by smart mobile devices was assessed in normal and healthy adults.Fifty-nine volunteers (age, 38.16 ± 10.23 years; male : female = 19 40) were exposed to tablet computer screen stimuli (iPad Air, Apple Inc.) for 1 hour. Participants watched a movie or played game on computer.

Risk factors associated with myopia in schoolchildren in Ireland

British Journal of Ophthalmology, Год журнала: 2019, Номер unknown, С. bjophthalmol - 313325

Опубликована: Фев. 11, 2019

Aim To examine the demographic and social factors associated with myopia in schoolchildren Ireland. Methods Thirty-seven schools participated, representing a mix of urban rural socioeconomically disadvantaged non-disadvantaged areas Examination included cyclopleged autorefraction (1% cyclopentolate hydrochloride). Height weight participants were measured. Parents filled participant’s lifestyle questionnaire, including questions on daily screen time use daylight exposure. Myopia was defined as spherical equivalent ≤−0.50 D. Results Data from 1626 (881 boys, 745 girls) two age groups, 6–7 years (728) 12–13 (898), examined. prevalence significantly higher children aged old (OR=7.7, 95%CI 5.1 to 11.6, p<0.001) non-white ethnicity (OR=3.7, 95% CI 2.5 5.3, p<0.001). Controlling for group ethnicity, also linked height (p<0.001) following groups: using screens >3 hours per day 2.1 6.3, p<0.001), obesity (OR=2.7, 1.9 3.9, sedentary (OR=2.9, 4.4, frequently reading/writing (OR=2.2, 1.4 3.5, p=0.001), less exposure during summer (OR=5.00, 2.4 10.3, spring season births (OR=1.9, 1.1 3.3, p=0.02), paternal history (OR=2.4, 1.8 bottle fed first three months life (OR=1.7, 1.3 2.5, p=0.02). Conclusions The associations found between Ireland suggest that longitudinal research investigating these may be beneficial advising preventative public health programmes.

Screen time duration and timing: effects on obesity, physical activity, dry eyes, and learning ability in elementary school children

BMC Public Health, Год журнала: 2021, Номер 21(1)

Опубликована: Фев. 28, 2021

Abstract Background As internet use becomes more widespread, the screen time (ST) of elementary school students increases yearly. It is known that longer durations ST can affect obesity, physical activity, dry eye disease, and learning ability. However, effects just before bedtime have not been clarified. Therefore, we examined duration timing on children. Methods We conducted a survey 7419 in Tokyo, Japan using questionnaire food education. (just bedtime) served as explanatory variables, relationship between eyes, ability was analyzed logistic regression analysis. Gender, year, height, weight were considered confounding factors. First, whether related to each objective variable, univariate model examine all variables. Thereafter, performed multivariate analyses for variables showing significant difference models. Results A association observed academic performance, indicating may lead decreased performance. associated with immediately contributed reduced Furthermore, results investigating combined effect (immediately these factors revealed has greater Conclusion Our findings indicate children ability, they suggest only but also important.

Plasmonic Contact Lenses Based on Silver Nanoparticles for Blue Light Protection

ACS Applied Nano Materials, Год журнала: 2024, Номер 7(6), С. 5956 - 5966

Опубликована: Март 6, 2024

Constant exposure to blue light emanating from screens, lamps, digital devices, or other artificial sources at night can suppress melatonin secretion, potentially compromising both sleep quality and overall health. Daytime elevated levels of also lead permanent damage the eyes. Here, we have developed protective plasmonic contact lenses (PCLs) mitigate exposure. Crafted poly(hydroxyethyl methacrylate) (pHEMA) infused with silver nanoparticles, these serve as a barrier filter light. Leveraging properties effectively filtered out undesirable (400–510 nm), demonstrating substantial protection (22–71%) while maintaining high transparency (80–96%) for desirable (511–780 nm). The maximum level reaches peak 79% 455 nm, aligned emission sourced LEDs in consumer displays. presence nanoparticles was found an insignificant impact on water content lenses. maintained retention within range 50–70 wt %, comparable commercial optical performance remains unaffected tears lens storage solution over month no detected leakage nanoparticles. Additionally, MTT assay confirmed that were biocompatible noncytotoxic, cell viability 85% after 24 h incubation. These could be potential protect against most intense wavelengths emitted by displays offer remedy counteract deleterious effects prolonged
