Impact of Environmental Factors on Short-Term Eye Strain Relief during COVID-19 Quarantine: A Pilot Study

Abstract

Some policies implemented during the pandemic extended the time that students spend on electronic devices, increasing the risk of physical and eye strain. However, the role of different environments on eye strain recovery has not been determined. We recruited 20 undergraduate students (10 males and 10 females) from a university in eastern China and explored the restoration effects of their eye strain in different types of spaces (wayside greenspace, a playground, a square, and woodland) on campus through scale measurements. The results showed that the eye strain of the students accumulated by 15 min of e-learning was significantly relieved after 10 min of greenspace exposure compared to the indoor environment, and the recovery effect varied depending on the type of landscape. The effect of eye strain relief was found to be positively correlated with temperature, wind speed, visible sky ratio, canopy density, tree density, and solar radiation intensity, while it was negatively correlated with relative humidity. These findings enrich the research on the restoration benefits of greenspaces and provide a basis for predicting the effect of different environments on the relief of eye strain.

Eye Strain and Coated Glasses Preference: A Self-Reported Cross-Sectional Study of Urban and Rural Bankers in a Digitally Driven Modern Banking Landscape in Trinidad and Tobago (Preprint)

“…The demographic section of the results also declared a significant impact of areas (urban/rural) towards the preference to use anti-glare coating. The finding contrasts with past literature that shows the adoption of such innovative solutions more strongly in urban populations [28][29][30][31].…”

Spatial Vision Inequalities: A Literature Review of the Impact of Place on Vision and Eye Health Outcomes

“… 20 , 21 For eye health, green spaces have been associated with decreased eye strain and decreased refractive error. Lu et al 22 found that exposure to green space for 10 minutes improved eye strain among university students using a 15-minute eye strain stimulus task (post-stimulation eye strain level of 8.20 ± 8.15 vs. post-relax eye strain level of 5.85 ± 6.45; P < 0.001). Huang et al 23 found that a higher neighborhood greenness level decreased the odds of having astigmatism in preschoolers’ by 45% (aOR = 0.55; 95% CI, 0.43–0.70; P < 0.001) and myopia by 38% (aOR = 0.62; 95% CI, 0.38–0.99; P < 0.05) after adjusting for the child's age and gender, parental education, monthly household income, and parental vision status.…”
