The problem with intromission theory of vision The intromission theory of vision is the belief that light hitting an object will bounce off the object, and the scattering photons will enter the pupils of the eyes creating the image of the object in your brain. This is not physically possible. Let me explain. Anyone familiar with the old "dot matrix printers" should be able to follow this reasoning. A single dot (photon) will not create an image on the page. The more dots printed, the more visible an image becomes. But more dots any the only issue. These dots have to be in a specific order, on the page, to create a recognizable image. And then you also have the issue of coloring the dots, in the precise locations, to create any specific image. Now the likelihood of randomly scattering photons, bouncing off an object, hitting your pupil in the precise order and frequencies, in the correct volume of dots (photons) to recreate an exact image of what you are seeing is physically impossible. And also, it must happen to both eyes with exactly the same pattern and frequency. There are three major factors that I observe, which are not consistent with current vision theory. 1. Image formation. 2. Image focusing. 3. Image transference to the brain. There is no way for random scattering photons to create the image of the object you are viewing. There is no way for the eyes to focus on photons. Our eyes actually focus on the object itself. However, light entering the eyes is necessary for transferring the image to the brain. And this is where I think the illusion of intromission theory comes from. Light does have to enter the eyes. But the eyes are resistant to direct light. so the light entering the eyes must be ambient light. Or else all that you would see is a blur. Not any specific or recognizable image. I think the lens of the eye is a translucent mirror. Imagine looking at a clear pane of glass. Even though you can see clearly through the glass, you can also see your image in the glass. This is how I postulate the images are formed in the eye. Then you have the retina and iris that are involved in focusing and color of the image. And finally, the ambient light transfers the image of the object to the brain. This is the only way that I can account for our ability to see everything at one time, from different distances, with different colors, in real time as we are moving and the objects are in movement. How do you see a bird in flight over your head? The light is coming from above the bird, and will be reflected in every direction. However, we observe the underbelly of the bird, while in flight. This also explains how we are able to view distant objects in space, in real time, without the light from these objects reaching us. Such random scattering of photons from every object in space, would not allow for anyone to see any image of stars and galaxies, with precision, based on current vision theory. But if our our eyes function as translucent mirrors, with only the need for ambient light to transfer images to our brain; then there is no limit on what we can observe in real time. Which is what we observe. Think about it.
