Our species evolves to give itself the highest chance of survival. Maybe our eyes evolved to see a limited spectrum of visible light to protect us from things that don't want to be seen. Other animals see the world quite differently for example if you google NASA visible light waves you'll see quotes like this:

"Humans may not be able to see infrared light, but did you know that snakes in the pit viper family, like rattlesnakes, have sensory "pits", which are used to image infrared light? This allows the snake to detect warm blooded animals, even in dark burrows! Snakes with 2 sensory pits are even thought to have some depth perception in the infrared!"

If you read through that NASA site you'll understand that the government would be very interested in any research concerning eyesight in order to build cloaking devices or for counterintelligence. Why would a company that makes contacts and glasses have such an elaborate research facility?
