Americans of all ages are impacted by vision loss. According to the Centers for Disease Control and Prevention, of the 14 million citizens experiencing debilitating visual impairment, 1.6 million are over the age of 50. There’s a serious need for enhanced therapeutic and rehabilitation treatment methods to assist these patients in performing daily activities.
Conditions like cataract, macular degeneration and glaucoma are common causes of vision impairment, especially in older adults. Mobility becomes a major issue for these patients, making it difficult for them to live a healthy lifestyle without full-time assistance. 
Mobility proves major issue for visually impaired
Although there are no current reports on how many people use canes and walking sticks to prevent accidents, according to the American Foundation for the Blind, the National Center for Health Statistics found that in 1990,approximately 109,000 people with vision loss in the U.S. used long canes to get around. The National Federation of the Blind also noted statistics from Guiding Eyes for the Blind stating that 10,000 guide dog teams were working with the visually impaired to prevent accidents and collisions in 2014. 
The Falls Prevention Center of Excellence explained that those with visual impairments have more than double the chance of falling than people with normal vision. For older adults, this risk is even greater, as seniors often simultaneously experience a number of additional age-related factors, such as hearing loss and arthritis. These patients need reliable devices and treatments to assist them with their mobility issues.
New wearable device improves mobility
Massachusetts Eye and Ear Infirmary has recently developed a wearable device to help people with peripheral vision loss. The device was designed to warn patients when they come too close to an object to prevent them from colliding with it.The device is unique, as it sends auditory warnings to the user when he or she is approaching an object instead of when he or she passes by or stands close to it. ……
