boyfriend, he has weird eyes, why is that?

If his eyes point into the nose it is called being “cross-eyed”. What you are describing sounds like a lazy eye, the muscles of the one wandering eye isn’t strong enough to hold it in natural alignment like the other eye. There are varying degrees of having lazy eye from mild (hardly noticeabel) to severe (a good friend of mine can never drive a car because hers is so bad).

There is surgery to correct this. 40 years ago I had 2 surgeries that didn’t help much, today the procedures are probably much more successful

He may be rather sensitive about this, so if you decide to ask him about this then be very compassionate and caring when you address it. If it bothers you a great deal then you may need to look for another boyfriend, but hopeful you like him for what’s inside and not what’s seen on the outside???!!!
