Dae Shik Kim, PhD, et al.

Most blind individuals use a long cane to detect drop-offs and other sunken surfaces. In the current study, younger cane users detected drop-offs more reliably than older cane users. Cane users who lost their vision earlier in life also detected drop-offs more reliably than those who lost their vision later in life. The findings of this study may help blind individuals select appropriate cane techniques for better drop-off detection based on how old they are and when they lost their vision.
