Hazard detection with a monocular bioptic telescope (2015)

Amy L. Doherty Eli Peli Gang Luo

Purpose: The safety of bioptic telescopes for driving remains controversial. The ring scotoma, an area to the telescope eye due to the telescope magnification, has been the main cause of concern. This study evaluates whether bioptic users can use the fellow eye to detect in hazards driving videos that fall in the ring scotoma area.

Conclusions: Detection of driving hazards is impaired by the addition of a secondary reading like task. Detection is further impaired when reading through a monocular telescope. The effect of the partially‐occluding bioptic supports the role of the non‐occluded fellow eye in compensating for the ring scotoma.
