This study tested whether a new dynamic color temperature mode on screens can prevent dry eye and visual fatigue. Thirty adults read text on a screen for 50 minutes under different color settings. Researchers measured eye fatigue and dryness before and after to see if the new mod…

This completed study tested whether taking anti-aging compound capsules twice daily for four weeks could reduce eye fatigue and discomfort in 25 healthy adults aged 20 to 60. The capsules contained a mix of botanical extracts, omega-3s, vitamins, and minerals. Researchers measure…

This study tested whether a special yellow-light, anti-glare phone screen could reduce eye strain and dryness caused by using a phone for 2 hours in a dim room. 70 adults with mild nearsightedness took part. Researchers measured tear quality, eye redness, and other signs of eye f…

This study tested whether a 'comfort reading mode'—changing background and text colors on a screen—can prevent dry eyes and visual fatigue. 35 adults read on a screen for 45 minutes under different color settings. Researchers measured eye fatigue and dry eye symptoms before and a…

This study tested a new type of blue-blocking glasses designed to reduce eye strain from computer screens. Twenty-five adults wore the glasses while working on digital devices, and researchers measured changes in eye fatigue, tear film stability, and focusing ability. The goal wa…

This study tested whether a 'dynamic defocus' display mode can help reduce visual fatigue in adults who regularly use screens. 36 participants watched videos with different display settings, and researchers measured eye focus ability and tiredness. The goal is to find a simple wa…

This study tested whether acupuncture can relieve eye fatigue. Thirty adults who often feel eye strain from screens were split into two groups: one got real acupuncture, the other got a fake (sham) version. Researchers measured how well the eyes could focus before and after treat…

This study tested whether special anti-reflection and circularly polarized films placed on smartphone screens can reduce dry eyes and eye strain caused by close-up screen use. 120 adults with mild nearsightedness used phones for 45 minutes in light or dark settings. Researchers m…

This study tested whether 0.05% cyclosporine eye drops can improve symptoms of mild to moderate dry eye. Researchers enrolled 60 adults and compared the drops to standard artificial tears. The goal was to see if the drops reduce eye inflammation and ease discomfort like tired eye…

This study tested whether using a red-light device twice a day for a month can reduce visual fatigue in people aged 40 and older with presbyopia (age-related difficulty seeing up close). Sixty-six participants either used the real device or a sham device. Researchers measured cha…

This study tested whether taking a daily probiotic capsule for 35 days can reduce dry eye symptoms in adults aged 20 to 65 with confirmed dry eye. Researchers measured tear production, tear quality, and eye surface health before and after the treatment. The goal was to see if pro…

This study tested two approaches—oculomotor (eye movement) exercises and muscle energy technique—to reduce visual fatigue in 44 adults with forward head posture. Participants did the exercises for 4 weeks, 3 days a week. The goal was to see which method better improves eye strain…

This study measured muscle activity in surgeons performing hysterectomies with robotic assistance versus conventional laparoscopy. The goal was to see which method causes less physical strain, potentially reducing work-related injuries. Four trained surgeons participated, and the…
