Reducing motorcycle accidents by improving eyesight
Slashing Two-wheeled Accidents by Leveraging Eyecare: a Stepped-wedge Cluster Randomised Controlled Trial to Assess Impact of Spectacles on Reducing Crash and Near-crash Events Among Myopic Motorcycle Drivers in Ho Chi Minh City Vietnam
This study is testing if giving glasses to young motorcycle drivers in Vietnam can help reduce accidents and near-misses on the road.

What this trial studies
The STABLE trial aims to evaluate whether providing spectacles to correct myopia can decrease the number of crash-near-crash events among young motorcycle drivers in Vietnam. This stepped-wedge cluster randomized controlled trial will recruit 625 students from five universities in Ho Chi Minh City, assessing their driving safety under naturalistic conditions using a Data Acquisition System. A pilot study with 35 students will precede the main trial to test the system and develop a crash event dictionary. The study seeks to highlight the importance of vision correction in enhancing road safety in low and middle-income countries.
Who should consider this trial
Good fit: Ideal candidates are students aged 18 to 23 with uncorrected or under-corrected myopia who regularly use motorcycles for transportation.
Not a fit: Patients with ocular or systemic abnormalities affecting vision will not benefit from this study.
Why it matters
Potential benefit: If successful, this study could significantly reduce motorcycle accidents among young drivers by improving their vision.
How similar studies have performed: Previous studies have indicated a strong correlation between poor vision and increased crash risk, suggesting that this approach has potential based on existing evidence.
