Scientists discovered we were wrong about our belief regarding insect vision. It seems they can generate images at much higher resolution than we used to think, so they can perceive more details. The previous theory was given by the fact that their eyes are made up of a series of lens-like units, which seemed unable to capture clear images of the surroundings.
Scientists thought insect vision was poor
An insect’s eye contains thousands of compound units which resemble lenses. These units, instead of working individually, capture only parts of images which should cluster into one single low-quality picture. However, it seems that they can do more than that.
A team of researchers from the University of Sheffield discovered that insect vision could be better. Those compound eyes are capable of producing high-resolution images thanks to the receptors inside them. When light comes into contact with the eyes, these receptors have to perceive the movement produced by it. They developed a study, which was published in the journal eLife.
Researchers managed to understand the high-resolution mechanism behind insect vision
To understand how the entire process works, researchers used a high-speed microscope, as its mechanism is similar to the one behind insect vision. As their head and eyes move, they perceive the world in short bursts of images. As these bursts combine with light, they are able to create a much broader picture of the surroundings, containing all the details.
These photo receptors placed inside the compound eyes surprised the scientists, as they proved they can produce much clearer images than it was previously perceived. Their mechanism is accurate enough to produce high-resolution insect vision.
In fact, all animals, together with humans, perceive the world through eye movements and short bursts of images which follow one another. Insect vision turned out more advanced, as the receptors inside the eye compounds found an accurate way adjust the light they receive to all these movements and bursts. In the end, the result is a clearer image.
