Ok so I have an Astigmatism in both eyes. I’ve worn glasses since I was in middle school last time I went to get my eyes checked the dr asked me had anyone ever told me I had a slight lazy eye. Can they develop in adult hood?

Define lazy. Some use the term to describe one eye drifting away fro the focus point. Many use it to designate when the brain has decided to decrease the accepted input from a weaker eye to eliminate a blurred or distorted image. This often comes on quietly if the issue causing it is not treated early. I would clarify what your eye doc means & ask them.
