What this trial studies

This study investigates the protective effect of TheaLoz Duo lubricating eyedrops on the ocular surface of handheld console and computer gamers suffering from dry eye symptoms. Participants will be randomly assigned to receive either the eyedrop treatment or a control condition over two months, with assessments conducted at the Aston Dry Eye Clinic. The study aims to determine if these eyedrops can alleviate symptoms of dry eye disease caused by prolonged screen use.

Why it matters

Potential benefit: If successful, this study could provide a simple and effective solution for gamers to protect their eye health and reduce discomfort associated with dry eye syndrome.

How similar studies have gone: While there is limited evidence specifically for gamers, similar studies have shown that lubricating eyedrops can be beneficial for individuals with dry eye symptoms.
