Prolonged screen use is common in daily work and study and may cause blurred vision, eye soreness, dryness, headache, and reduced attention. Light environment may be one way to improve visual comfort during screen use, but more controlled clinical evidence is needed.\n\nIn this randomized, parallel-group controlled study, 112 healthy adult participants will be assigned to either a full-spectrum screen bar lighting group or a brightness-matched control group without screen bar lighting. Participants in both groups will complete an approximately 2-hour standardized screen task in a controlled laboratory environment. The study will compare changes before and after the task in objective and subjective measures of visual fatigue and dry eye, including critical flicker fusion frequency, visual fatigue questionnaire scores, eye movement and blinking parameters, pupil parameters, tear film-related measurements, and dry eye symptom scores.

There is limited evidence for the protective effect of lubricating eyedrops on the ocular surface for handheld console and computer gamers.\n\nThe aim of this study is to investigate the protective effect of a lubricating eyedrop (TheaLoz Duo) on the surface of the eyes in handheld console and computer gamers. The main question it aims to answer is whether TheaLoz Duo could protect the surface of the eyes from dessication and alleviate symptoms of dry eye disease in handheld console and computer gamers.\n\nParticipants will receive either the lubricating eyedrop first for 1 month, followed by a control condition (no eyedrops) for another month, or the other way round.
