Through the Eyes of A Dog

A contact lense allowing human night vision.

Organism: Dog

A dog has many different talents besides being man's best friend. A dog's pupil is much larger than a human's which allows their eyes to see more light. The center of the retina has more of the light-sensitive particles, which work better in dim light. The light-sensitive compounds in the retina respond to lower light levels. And the lens is located closer to the retina, making the image on the retina brighter. Dog's also have something called the tapetum. This mirror-like structure in the back of the eye reflects light, allowing the retina to reflect light twice to register light that has entered the eye.This is what also causes dog's eyes to glow at night.

Dogs Helping Humans

So how can a dog's eyes help us? Humans evolved in the daylight, which means our eyes are much stronger in the day time. When humans are in the dark, their vision is not very good. This is because the makeup of our eyes is different than the makeup of dogs.

With the creation of dog-like contacts, night vision will no longer be a problem for humans. Many people have a hard time driving at night because their vision is not as good in the dark. With these easy to use contact lenses, their eyes will be just like a dog's. These contacts could also be used by hunters, soldier, construction workers who work at night, etc.

How Does It Work?

I have created a special contact lens that will allow humans to see at night just as well as their dog. These contact lenses are just like any other contact lens that people wear. If you already wear contacts, don't worry. This lens can be placed over those. This lens works just like the eye of a dog. The lens allows the pupil to expand and the retina to draw in more light. They also give humans a tapetum in their eye, which is what gives dog's extra light at night.

Prototype 1: Here you see the normal human eye.
Prototype 2: The pupils are dilated in this image.
Prototype 3: The pupil continues to expand drawing in more light. The retina is more light sensitive.
Prototype 4: Tapetum is activated.
