I swear I think advertisers are doing this intentionally. I see banner ads on the web all the time that catch my attention because from the corner of your eye, they look like something dirty, so you look. Advertisers know sex sells, so I think this is 100% purposeful. Look at the Adobe ad below just with your peripheral vision and tell me it doesn't look like a set of boobs with a low cut top. I'm on to you, advertisers!
