Which is right?

The img sometimes fails to be seen here.
One of the most often asked and most controversially answered questions is, “What should I do when I meet a blind person?” A quick Google search will turn up plenty of answers, which are quite different from each other. So, clearly, there is no general agreement on what to do when you meet a blind person.
There are no special rules or do s and donuts that can deal with this situation. There is only one principle, Blind people are nothing more nor less than people who happen to be blind. As such, it is our own job to take care of ourselves, and we are grateful to no one else for special care or leadership. For we think we are equal to normal people.
The best thing to do is nothing. Don't suppose you know what we need. If we do need something, we'll politely let you know.
Forget everything you've heard about the blind,even if you consider yourself to be an expert. Blind people have plenty to say about experts. Especially, forget anything you've heard or read about “Ten Things to Do If You Meet a Blind Person”. The advice will probably just cause more embarrassment. Most of it is made up by sighted people anyway and doesn’t necessarily stand for the blind's view.
There is completely no way to second-guess the situation by imposing any pre-formed ideas. Even if  you have known other blind people, don't think you know what to do with every one of them. The thing that often makes us angry is to hear "It’s OK. My mother （sister, cousin, friend） is blind."
Blind people are as different from each other as any two people on this earth. There are no similarities among us that you can depend on. Even the degree of vision, hearing or touch that we use can be very different. Most blind people do have some degree of vision, and even the very few of us who are totally blind may use our touch and hearing very effectively.
