Vision impairment encompasses a spectrum from mild low vision to complete blindness. Walking mobility is affected by vision impairment at every level of severity -- depth perception errors, contrast sensitivity loss, and peripheral field loss all increase trip and fall risk. There is an important distinction that must be made clearly at the outset: the long white cane used for orientation and mobility (O and M) by blind and severely vision-impaired people is a different tool from a walking support cane. Each has a distinct purpose, and they are not interchangeable.
The Two Types of Cane in Vision Impairment
| Cane Type | Purpose | Technique | User Group |
|---|---|---|---|
| White cane (long cane / symbol cane) | Obstacle detection; navigation; signals visual impairment to others | Two-point touch technique; arc scanning of path ahead | Blind or severely vision-impaired; taught by O and M specialist |
| Support / walking cane | Balance; weight-bearing support; fall prevention | Standard weight-bearing cane technique; held contralaterally | Any person with gait instability, joint pain, or balance deficit |
| Support cane (white or coloured) | Combined signal and support for partially sighted with balance deficit | Weight-bearing support; short length | Partially sighted with both navigation and balance needs |
When Vision-Impaired People Need a Support Cane
A person with vision impairment may need a support walking cane (in addition to or instead of a white orientation cane) when:
- Concomitant joint disease (arthritis, peripheral neuropathy) affects gait stability independently of the vision loss
- Diabetic retinopathy (the most common cause of acquired vision loss in working-age adults) is associated with diabetic peripheral neuropathy, which independently impairs proprioception and balance
- Age-related macular degeneration in older adults is associated with general age-related gait decline; the patient needs both vision rehabilitation and gait support
- Glaucoma with peripheral field loss: peripheral field loss impairs obstacle detection to the sides; a support cane in one hand while navigating is appropriate
Dual Use: White Cane and Support Cane Together
Some people with vision impairment use both a white cane (in one hand) and a support cane or forearm crutch (in the other hand) simultaneously. This provides both obstacle detection and weight-bearing support. This dual-cane approach requires coordination and is typically taught by an O and M specialist. It is most common in people with combined vision impairment and peripheral neuropathy or lower limb weakness.
DaiWalk Cane Features for Vision-Impaired Users
For vision-impaired users using a DaiWalk walking cane for support, the Anatomic Grip provides tactile orientation (the user can feel the correct grip orientation by shape alone, without looking). The Steady Tip 6.2 cm2 contact patch provides consistent ground feedback through the shaft -- vibration damping in wood allows subtle surface texture variations to be felt through the cane, providing additional environmental information.
