Prismatic Lazy Glasses actually work, pretty much
See the original posting on Boing Boing
I can’t remember quite how I came to be in possession of a pair of these Prismatic Lazy Glasses (Amazon), but the most shocking thing about them is they actually work. You put them on, lie down completely prone, and can see at a 90° angle: perfect for watching TV (or reading) in bed without sitting up or craning one’s neck.
The effect is not perfect. They create tunnel vision, and the imperfect build quality of the glasses and presumably the mirrors results in more eye strain that you’d normally experience. (Though certainly less than I experience with VR)
Whether eye strain wipes out the advantage of bodily relaxation is for you to decide; my only problem is falling asleep during practically everything.
Note that the link here is to a well-reviewed model from Amazon I assume is identical to the pair I have. I can’t imagine there are vast quality differences between different brands of $10 lazy specs, but you never know.
