Not sure if this is your older or younger son. When DS first learned about blinking/winking he would go around blinking at everyone. However, he also told us that is what he was doing "I'm winking". So, it may be he just figured out how to do this.
DS wears glasses - we had no clue he needed them but since I had glasses since 1st grade (eye patch in K) we took him in for a checkup around age 3 and found he needed them. I don't recall him blinking alot before that.
