It seems like you can't walk more than a few blocks in the city without some strange person trying to make eye contact with you.
They lock eyes, smile, sometimes they wave or say hello, all the while acting like the fact that they put forth the effort to make eye contact entitles them to a free peek at your peepers.
But you can battle inappropriate eye contact by consulting this comic strip from Iguana Mouth and finding a method of eyeball avoidance that works for you.
However, I wouldn't suggest transforming into an eldtritch monstrosity unless you have a really good health insurance plan.
