A white cane for the blind and visually impaired has become a symbol of independence as well as an opportunity to bring awareness to others to provide extra precaution and courtesy to the user.
A white cane benefits those with all different kinds of visual losses
such as loss of depth perception, central vision or peripheral vision.
Declining Depth Perception
The loss of depth perception or the
ability to perceive distance is another common symptom for those with macular degeneration. Combined with the loss of contrast sensitivity, these two vision changes can affect one’s life and safety in many
different ways. Difficulty distinguishing how far away an object is can make driving unsafe. The inability to distinguish the curb from the sidewalk provides an increased risk for falls and difficulty seeing and navigating stairs also provides another safety risk.
Loss of Contrast Sensitivity
Those with vision changes association with macular degeneration are at a high risk for falls and accidents.
Loss of depth perception is reduced when there is loss of visual
contrast. Two healthy functioning eyes working together are required
for good depth perception.
So even if you have one good eye, depth perception is decreased. While this vision loss can’t be completely overcome there are some strategies and vision aids one can use to help compensate.
"I hated to admit that I was blind, because it was a change in my self-image. I still had that majority view of blindness, that it was a terrible thing.
I knew that the white cane identified me as a blind person, and I only thought of this negative purpose," shares Thomas Bickford, author of Care and feeding of the Long White Cane.
Thomas Bickford soon learned that the cane would serve as his friend and
give him confidence to travel safely and independently.
The author of Care and Feeding of the Long White Cane recommends:
"The cane needs to reach a good two steps in front of where you are stepping. As a practical matter, if you find yourself overstepping the cane, dropping off curbs you didn't find, try a longer cane."

A short video on white cane use:
The National Federation of the Blind (NFB) offers free white canes to eligible participants in the fifty states, the District of Columbia and Puerto Rico.
The length of the cane matters. First time users will start out with a shorter cane, while those with more experience will progress to a longer one. The NFB recommends that adult first time cane users measure from their shoulders to the floor. One can request a free cane more than once. So when a longer cane is needed, another request can be made.
President Lyndon B Johnson proclaimed October 15th as White Cane Safety Day in 1964 with these words:
"The white cane in our society has become one of the symbols of a blind person's ability to come and go on his own. Its use has promoted courtesy and special consideration to the blind on our streets and highways. To make our people more fully aware of the meaning of the white cane and of the need for motorists to exercise special care for the blind persons who carry it Congress, by a joint resolution approved as of October 6, 1964, has authorized the President to proclaim October 15 of each year as White Cane Safety Day."
"The mission of White Cane Day is to educate the world about blindness and how the blind and visually impaired can live and work independently while giving back to their communities, to celebrate the abilities and successes achieved by blind people in a sighted world and to honor the many contributions being made by the blind and visually impaired."
