Hello, may you help me?

Our teachers said it was possible to use:

She has to have had to wear glasses since childhood.

I didn't find it anywhere, so that I'd like to ask:
Do I have to think about the tense? Does it mind that it's a present perfect??
Shouldn't I use just 'She has to wear glasses since her childhood'?

The meaning was: A girl which is 16 wears glasses. When she was 5 doctor tell her to wear glasses. She has been forced to wear them.

Thank you!

"She has to had have wear glasses since her childhood." This is incorrect. The correct way to say it is "She has had to wear glasses since her childhood".

Is it necessary to think about the tense? If I used just: She has to wear glasses since her childhood , would it be incorrect?

It would be OK.

This is one of the rare occasions when I disagree with bhaisahab. For me, that it unacceptable; it must be, "She has had to wear glasses since her childhood".

from?

I agree that it requires the present perfect. She has had to wear them

And "since" not "from."

Barb, can you please tell us what you think about the use of the Present Perfect discussed in this thread:
