How does refraction cause an optical illusion please answer?
Optics is the study of how light (moreso Electromagnetic Radiation) travel and interact with objects (solid state physics, electrodynamics etc.). Optical illusions deal with how light is interpreted by the human brain. So optics studies how light gets to the eye, optical illusion is about how the brain perceives that light.
When light is absorbed by a rod cell what happens?
The optic nerve then gets triggered, and sends a signal to the brain. Our amazing optical centers then translate the signals into an image of what we're seeing.
How do artists create optical illusions?
When light from a lighter medium enters a heavier medium like from air to glass the refraction occurs towards the normal. However when light passes from a heavier medium to a lighter medium the refraction occurs away from the normal. As the incident angle in this case keeps incresing the refracted light keeps moving away from the normal until it reaches a critical angle when total internal reflection occurs. Thus on a hot day when you travel on a highway that is paved, the air near the surface gets hotter and lighter than the air slightlyabove it. As we drive we can see this total internal reflection occurring which gives you the illusion that there is a water puddle at a distance when in actuality there is no water. This is a mirage and this is an example of optical illusion. The brain processes the signals and gets slightly confused and we see illusions. There are many such optical illusions in nature (and man made).
How does an optical code read?
Optical Code is read on the principle of beam reflection. Initially a beam is made to incident onto the optical code. As the beam gets reflected, it is analyzed for the verification of the code.

Does reading help the brain?
Yes, the brain gets all the words in the mind and eventually the mind would be able to use that word. It also gets the brain familiar with other words.
