Your analogy works too well to leave this alone. To test my understanding, would this work? Blind people have these disadvantages, whether sighted people see them or not. Even if it works, the rest of that paragraph is too effective to even consider changing it.
Many years ago, a friend who was blind and I took a three month road trip across American together. Along the way, I discovered that Miriam's hearing, sense of smell, taste and skin were far stronger, sharper, and refined than mine (by a long shot).
As we travelled, Miriam shared what she picked up with her heightened senses and it felt like she'd turned on a light switch in me. Suddenly I could hear, taste, smell and feel things I never had before. Before our trip, parts of me were so numb, I could not access them. It took time, but eventually, I learned to trust all of my senses.
Lesson learned; when people stop relying on eyesight alone, and start developing their other senses, they expand their experience of life in really big and important ways.
Obviously, I hope, I found your article valuable.
