Read and her colleagues have since confirmed research from the 1980s showing that praying mantises really do have 3-D vision. In a 2016 paper, they used beeswax to stick tiny blue-and-green 3-D glasses on the faces of praying mantises and showed them 3-D movies of what appeared to be tasty-looking prey, finding that the insects lunged only at targets in the 3-D movies, not the regular 2-D ones.
3-D vision is a handy ability for praying mantises, which are skilled hunters of their fellow insects and are known to take down the occasional small bird.
Scientists already know how to confuse human 3-D vision - and so they set out to see if praying mantises would also fall, er, prey to those same tricks.
According to fellow researcher Jenny Read, this was a simpler method of 3-D vision
, and could have implications for building lighter machines, such as drones.

It is now an accepted fact that stereoscopic images (3-D images) cause an "intense eye accommodation activity"7 such as headaches, nausea, blurred vision, diplopia, asthenopia and visually-induced motion sickness(VIMS), which is characterised by tiredness, headache and soreness of the eye,8,9 collectively known as the 3-D vision syndrome.8,9 The phenomenon of the 3-D vision syndrome has been strengthened by researches conducted in Rome, Italy.
After a thorough literature search and with the best of our knowledge, no substantial data is available on this topic (3-D vision syndrome) in our region.
NASA is asking coders to create algorithms for Robonaut 2, or R2, that will improve its 3-D vision
. The Robonaut Vision Tool Manipulation contest kicks off on Feb.
This is accomplished by restoring natural 3-D vision
and depth perception when performing laparoscopic procedures and is independent of a surgeon's skill level.
The new system, which is based on Versatile Volumetric Vision, a high-functional 3-D vision
system developed by AIST, can automatically discern various ampules and syringes and sort them out with precision.
The B-42 dual lane portion cutter offers accurate portioning due to a precise, high capacity 3-D vision
The Scion(R) 3-D Vision
[System.sup.TM] is the first totally integrated system that can be used with all stereo and monocular endoscopic imaging products existing in the marketplace.
