Understanding the different types of visual impairment is a good way to educate yourself on the various challenges that visually impaired individuals must navigate on a daily basis. This will help you gain a better idea of the importance of audible and tactile warning systems.
This video provides an overview of the different types of visual impairment. Total blindness occurs when an individual cannot perceive light or any forms, whereas light sense blindness occurs when an individual can sense the presence or lack of light but cannot distinguish forms. Both of these visual impairments fall under the category of legally blind, or when an individual’s visual acuity is 20/200 or less. Watch this video for more information on the other types of visual impairment.
