Digital screen use linked to eye strain, physical pain, and sleep issues
Prolonged use of digital screens is linked to various physical health issues, including ocular strain, musculoskeletal pain, and sleep disruption. Experts note that excessive screen time can lead to digital eye strain, characterized by dryness, redness, and blurred vision, often caused by a significant reduction in blinking frequency. In some cases, using devices in low light has been shown to increase intraocular pressure, which may pose risks for individuals with glaucoma.
Beyond vision, improper posture during device use can cause “text neck” syndrome, muscle tension in the shoulders, and repetitive strain injuries in the wrists and fingers. Orthopedists recommend taking breaks every 30 to 60 minutes to move and stretch.
Furthermore, nighttime scrolling is identified as a major disruptor of biological sleep cycles. While much focus is placed on blue light and retinal damage, the disruption of the internal clock is a primary cause of poor rest. Notably, recent reviews suggest that blue light filters may not provide significant benefits against digital eye fatigue.
