brain tumors affect whatever part of the brain they are in. If they are in the occipital lobe (the part of the brain that processes vision) they will affect the vision in multiple ways depending on where in the occipital lobe they are. I have heard of blindness, inability to see color (black and white vision), and many other peculiarities in vision due to tumors in the occipital lobe.
Scientists do experiments to see what is going to happen. First, they make a hypothesis or guess about what they think will happen. Then, they do an experiment to see if their guess is right or wrong.
You experimentally test it
To understand. To see if they're right.
My teacher verified my test to see if it was finished.
I think your brain processes visual information first because you naturally see things before you hear them. Like when you see a person hit a pitch, you see it but and instant later you hear the "crack". That has to do with light traveling faster than sound.
You see light when your vision receptors take in the electromagnetic wavelengths and your brain processes the light, as well as color.

Your brain interprets the optical illusion based on the information received by your eyes. The eyes detect the visual stimuli, and the brain processes and interprets this information to create the perception of the optical illusion.

There are many tests that can help, but first I must see an x-ray of your head. Because i'm not sure your brain is big enough to understand the real answer.
No, our eyes see things right-side up, but the brain processes the images upside down before correcting them.
Objects are perceived in the following order: first, light reflects off the object; second, the light enters the eye through the cornea and is focused by the lens onto the retina; third, the retina sends signals to the brain through the optic nerve; finally, the brain processes these signals and interprets them as the object we see.
light gets reflected off objects and enters your eyes. Your eyes then transmit this information to your brain, which processes it and allows you to see the objects around you.
At first when the eyes will see only what they can see, but then then the brain will make the eyes see what there looking for.
Light from the sun, or other light source, reflects from the tree into your eye. Structures in your eye focus the light onto your retina, which sends nerve signals to your brain. Your brain processes those signals and you "see" the tree.
Color is the perception of different wavelengths of light by the human brain. The brain processes the signals received from the eyes and interprets them as various colors based on the stimulation of different color-sensitive cells called cones in the retina. The brain then combines this information to create our perception of the colors in the world around us.
