For at least the last decade, I’ve been obsessed with lazy eyes. First and foremost, with celebrities who have them – Paris Hilton, Keri Russell, Tina Fey.

But secondly, and perhaps more terrifyingly, with the possibility that I might have one myself. And that, even worse, like the sufferer of persistent halitosis, I’d be the last to know about it.

Obviously, that’s a ridiculous concern. Which I know because I’ve both analyzed enough of my own photos to confirm eyeball alignment, and because, every time I tell someone about my ocular neurosis, they jump in to reassure me.

But fast-forward to a month or so back, when I’m picking out a pair of sunglasses from one of Jess’ client, Jordan Silver, owner of a high-end vintage sunglass boutique. I call in to my uncle (and optometrist) Robert, and ask his office to fax over my prescription.

Diopter. Astigmatism. Prism.

Prism?, I ask.

Yes, Jordan explains. Prism. Correction for a tendency of the eyes to try and pull apart in use.

As in, a lazy eye?

Well, technically, yes. Not the kind (like strabismus) that fascinates me most. But a form of lazy eye nonetheless.
