Study Finds 81.2% of Spaniards Perceive Vision Deterioration from Screen Use

A survey by Visión y Vida and the Fórum de Gafas, Lentes y Monturas involving 1,402 respondents indicates that 81.2% perceive their vision has worsened due to habitual screen use. The study highlights that 35.8% spend five or more hours daily on computers or tablets, while 65.1% report occasional visual fatigue. However, experts caution that these findings reflect subjective perceptions rather than proven causality, noting a lack of solid scientific evidence linking screens directly to vision loss. Instead, screens may reveal underlying visual system inefficiencies. Regional data shows Catalonia leads in high computer usage at 45.8%, while Galicia reports higher light sensitivity issues. The report emphasizes prevention and public awareness regarding near-vision demands without confirming direct physiological damage from devices.
