How I am contradicting myself?
I think its a private matter about Rav Yosef’s eyes, now if he wants everyone to know the reason (I dont know or not if he does) thats another issue
In that thread I just posted public information anyone can google, Just like it acutally is no secret why rav Yosef wears the sunglasses, but the OP didnt know that. What if the OP had asked about something that was not well known and some people did know the answer. He is a public figure so its a bit harder to hide information about him
