This is a question about glasses. when someone points at something, for example they'll say "hey can you get that blue container right there ? " and point at it and i'll still be saying "where ? " even if its in front of my face. my vision isn't blurry or anything so i don't know what it is and it happens every time someone points at something or tells me to get something. does this mean i need glasses, maybe to points things out a little bit more to me ?
