G-Screen is a free online glaucoma awareness tool that guides the public through a peripheral vision screening experience using validated visual field technology. Developed by Australian optometrist John Nguyen (BOptom, 20+ years clinical experience), G-Screen is available at g-screen.online and can be completed in under 6 minutes on computer/tablet with internet access – no appointment, no referral, no cost.
The tool uses MRF/GLANCE Optical’s FDA/TGA-registered visual field technology and is supported by an advisory panel including glaucoma subspecialists A/Prof George Kong and Prof Algis Vingrys (Emeritus Professor, University of Melbourne). Results include personalised education and a prompt to see an eye care professional for full assessment.

G-Screen is designed to reach the unscreened majority – people who have never had a visual field test and don’t know they’re at risk.
