How many bind and deaf are there in the world?

As of recent estimates, approximately 466 million people worldwide are affected by disabling hearing loss, with a significant number also experiencing vision impairment or blindness. The World Health Organization has reported that about 2.2 billion people have near or distance vision impairment, and among these, there is a subset of individuals who are both blind and deaf. However, specific global numbers for those who are both blind and deaf are less clearly defined, making it challenging to provide a precise figure. Overall, these conditions highlight the importance of accessibility and support for affected individuals.
