Double Blind

I opened Facebook this morning and what do I (ha ha) see? An ad for not one, but TWO eye patches! Now, I’m not only wondering why Amazon thinks I need an eye patch, but do they think that I’m missing BOTH eyes and I need a pair of them? If that was the case then why not sell me sunglasses? And, if I WAS missing both eyes, how the HELL am I going to read their eyepatch ad?
