I found this great article about another low vision person learning to use and love their white cane for independent travel. IT’s on the Blindsight blog.
One of the highlights of my life was learning to use one. The white cane gave me security and freedom I did not previously have.
If you are losing your eyesight, are blind or low vision, I highly recommend you learn to use a LONG white cane. It givwes tremendous feedback about the environment.
