Spy Sunglasses — Who's watching your back?


These sunglasses allow you to see behind you while you're looking directly ahead.

They're like having a rear view mirror that no one knows about.

I had a pair back when I was in college — they really do work as advertised.

The only problem with them is that if you continue to stare to the rear, your eyes start to get really tired because the sunglasses do their trick when you look to one side without moving your head, using only your extraocular muscles.

Normally when you look to one side, you focus at a distance and move your head — visualizing your back with these requires you to focus up close on the inside surface of the lens while not moving your head, just your eyes.

Still, worth having.

From the website:

    Spy Sunglasses

    These spy glasses look like an ordinary pair of designer sunglasses, yet they have a unique feature — they allow you to see behind you.

    The lenses on these spy glasses have a special coating that allows you to look straight ahead and still see what is going on behind you.

    High quality designer aluminium frame with glass lenses with UV400 protection.

    It'll be like you have a rear view mirror with you.

    You won't need to turn your head so often.

    Stylish and great for walking and biking.

I was just wanting to make sure i understood this correctly, with these glasses a person can be looking str8 ahead and see directly behind them, is that right? You don't have to turn your head to the left or right to see what is directly behind you?

I would think you'd be focusing at a distance even if you're looking at a reflection. You're looking at an image that's far away, not at something printed on the glass.

The fatigue you experienced may have come from looking left or right for a long time (not something we're used to doing), or the mismatch between the focus in your mirror-gazing eye versus the other eye.

I'll leave out what size jeans (really, really huge, why not? size 8 looks really small in comparison!) I claimed to purchase recently (about me and joking to give some nonsense back!).

So, if you were to cross these with the Weight Loss Sunglasses, does that mean that nobody you'd see coming up behind you would look fat? Or, maybe they'd all just look unappetizing?

Skinny, unsavory people creeping up behind me...
