Study finds sight‑assistance device could put drivers at greater risk

Bioptic telescopes (BTs) are miniature binoculars that can be attached to regular eyeglasses to help people with low vision see more clearly. While they are permitted in other parts of the world, Australian standards have lacked clear guidance, creating pressure for policy development.

Led by Associate Professor Rwth Stuckey, La Trobe researchers used a Human Factors/Ergonomics framework to undertake a systematic review for the Victorian Department of Transport in 2025, analysing international evidence on BT use then assessing risk in varied Victorian driving conditions.

The review identified major gaps in existing research, particularly concerning cognitive demands and complex environments. BT use requires increased attention, which may heighten crash risk—especially when drivers encounter unexpected hazards. Cognitive walkthroughs of 19 driving tasks showed that BT use was often impractical and in many cases increased risk, particularly in high‑demand situations such as overtaking or navigating complex intersections.

The study concluded that although BTs may support personal mobility for some individuals, they provide minimal safety benefits and may increase overall road risk.

These findings informed Victoria’s 2025 decision to prohibit BT use for licensing, a policy now explicitly stated in the Department of Transport and Planning guidelines.

This research delivers a robust evidence base for a contentious policy area, supporting decisions that prioritise public safety over unproven technologies. Future research may revisit BT use in the context of autonomous vehicle developments, but current evidence strongly supports Victoria’s precautionary stance.
