Because of their forward-facing eyes, these animals lose the ability to see behind themselves, but they gain a type of X-ray vision that maximizes their ability to see in leafy environments. These animals evolved in cluttered environments, such as forests or jungles. Humans, primates, and other large mammals like tigers, however, have eyes pointing in the same direction.
These sideways-facing eyes give an animal panoramic vision-the ability to see in front and behind itself. Most animals-fish, insects, reptiles, birds, rabbits, and horses, for example-live in non-cluttered environments like fields or plains and have eyes located on either side of their head. Now, a new study by scientists at Rensselaer Polytechnic Institute in New York and the California Institute of Technology (Caltech) has uncovered a truly eye-opening advantage to binocular vision: the ability to see through things. Every material except lead.PASADENA, Calif.- The advantage of using two eyes to see the world around us has long been associated solely with our capacity to see in three dimensions. People fly, teleport, throw fire and magic-and yes, see through nearly every material in the world with their X-Ray vision. But mainly, because comic book physic don't have to play by the same rules as the real world if they don't wish to. So why isn't there a comic in which Superman's powers are accused of exposing people to radiation? Technically, Watchmen already covered that controversy. More than enough radiation to cause horrifying ecological and biological damage. Were Superman to go around using his X-Ray vision on anything and anyone around him, he'd be spreading around quite a lot of radiation. Not exactly what X-Rays are capable of, but comic books aren't exactly known for scientific accuracy. In that issue, he was able to see basically every single detail of a battle when looking through the ceiling of a building.

It was featured in Zack Snyder's Man of Steel and current Superman comic series writer Brian Michael Bendis featured the power in his Superman: Leviathon Rising #1 title released in March. While it might not be one of his go-to superpowers, Superman still puts his X-Rays to good use now and then. If he were able to see through anything and determine any detail from any distance, how are any of his villains going to get the upper-hand every now and then? Much like Kryptonite itself, this limitation was created to keep Superman from being all-powerful.
Lead is much too dense for X-Rays to breach, which is why patients around the world wear lead vests to protect themselves when getting their own X-Rays. So if Superman's heat vision can blast through lead, why can't his X-Ray vision see through it? Because actual X-Rays can't either! Superman might be able to see color, materials, and other fine details through his X-Ray vision, but actually X-Rays only discern the denseness of the material of what they're looking at. In the Men of Tomorrow arc, the Super Flare created a mushroom-cloud of chaos, demonstrating one of the most destructive uses of Superman's powers in comic book history. In fact, the heat vision was even upgraded when Geoff Johns created the "Super Flare" superpower in his late-New 52 Superman run in 2015. Since then, heat vision has become one of Superman's foremost powers, while X-Ray vision is more of a joke.
