What's causing my left eye looking at the center and making me look cross-eyed?

I have been wearing eyeglasses for 20+ years no contacts and i just noticed in my latest picture, i look cross-eyed but my vision's not doubling. I have astigmatism too.What's causing my left eye looking at the center and making me look cross-eyed?
i personally have a lazy eye and hate it, but ive had a very bad eye problem when i was younger, i haven't rubbed / touched my eyes in about 2 years or more,





but for you're problem i would go to a eye specialist and have them take a look at it, because it could get worse in the future and you'll have one eye pointing at you're nose and the other eye looking straight out.
