Overview
The excessive use of screens particularly amongst digital gamers can adversely impact the health of the surface of the eyes with symptoms and signs of surface damage. While strategies including limiting screen time exist, these may be ineffective given the widespread rise of digital device use and gaming culture in the modern era. There is limited evidence for the protective effect of lubricating eyedrops on the ocular surface for handheld console and computer gamers.
The 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.
Participants 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. Participants will attend 3 visits in total, each separated by 1 month apart. During each visit, routine clinical assessments of the front of the eye will be conducted. Subsequent findings from this timely study will help improve care of the surface of the eyes for a growing population of gamers worldwide.
Description
This study will be a randomized, outcome assessor-masked, cross-over clinical study to assess the potential impact of TheaLoz Duo lubricating eyedrop on symptoms and signs of dry eye disease in handheld console and computer gamers. All visits will be conducted at the Aston Dry Eye Clinic in Aston University, Birmingham, United Kingdom.
