Visual Impairments Simulation
Blindness is defined as having visual acuity of 20/200 or worse in the better eye with correction, or a visual field of 20 degrees or less. This affects approximately 39 million people worldwide, with an additional 246 million having moderate to severe visual impairment.
Some Statistics:
- 39 million people worldwide are blind
- 246 million have moderate to severe visual impairment
- 90% of visually impaired people live in developing countries
- 80% of visual impairments are preventable or treatable
People who are blind rely on assistive technologies such as:
- Screen readers - Software that converts text to speech or braille output
- Braille displays - Hardware that converts text to tactile braille characters
- Voice control - Software that allows navigation through voice commands
- Keyboard navigation - Using Tab, arrow keys, and shortcuts instead of a mouse
Try navigating this form using only your keyboard (Tab key) or with the screen reader simulator enabled to experience how blind users interact with web content.
