When I was first trying to figure out how likely it was I was on the spectrum, this was one of the things I assumed didn't apply. I would say to myself "Nah, never had a problem with eye contact"...until I thought about it properly, that is.
It is true that I never really had a problem with it. Certainly, when I was a kid, eye contact was not something that was seen as problematic compared with all my other issues with reading, writing, rocking, socialising, tantrums etc etc,
The strange thing about realising you are on the spectrum is realising just how many behaviours you assumed were normal are in fact not. I can make eye contact with people I am the closest to, apart from that, it takes real effort and makes me uncomfortable. If I am walking past someone at work or in the street I almost always find myself looking down at the ground in front of me or (as others have mentioned) busying myself with some imaginary task such as searching through my pockets or inspecting my fingernails. If I should somehow accidentally meet eyes with some stranger like this I feel massively anxious and tense. I get a sudden sense of panic I cant easily describe.
If I am able to mentally prepare myself for some eye contact in a situation where it serves some clear purpose and the other person is likely to expect it such as speaking to a cashier at a shop, I feel less overwhelmed but it is still uncomfortable.
I don't know if it is eye aversion or just poor memory but it occurs to me that I could not tell you the eye colour of anyone in my family apart from my wife.
