ClinConnect Summary
The STABLE trial is studying whether providing glasses to young motorcycle drivers with poor vision can help reduce accidents while they are driving. This research is taking place in Ho Chi Minh City, Vietnam, and aims to see if correcting myopia, or nearsightedness, can make roads safer. The trial will involve about 625 students aged 18 to 23 from five universities who regularly ride motorcycles. They must have at least one year of driving experience, use their motorcycle as their main way to get around, and drive a minimum of 50 kilometers each week.
Participants will be fitted with glasses if their vision can be improved to a better level. Throughout the study, researchers will monitor how often these drivers experience near-crashes or actual accidents while driving. The trial will last about 33 months, including 18 months of collecting data. By the end, researchers hope to show that better vision leads to safer driving, which could encourage stricter rules around drivers’ vision checks and promote the use of corrective eyewear.
