How can our eyes mislead us?
The basis of optical illusions is visual deception. It isn't your eyes playing a trick on you. Your eyes send signals to our brains through the retina, your brain then registers the information to create the image you are seeing. In the case of a visual illusion, the image the brain perceives differs from reality.
"These illusions happen very fast, perhaps in milliseconds," Dr Mareschal says. "And we found that even the higher brain cannot always correct for them, as it doesn't in fact know they are illusions." This is one reason why people's eyes sometimes mislead them when looking at objects in their visual landscape.
Optical illusions happen when our brain and eyes try to speak to each other in simple language but the interpretation gets a bit mixed-up. For example, it thinks our eyes told it something is moving but that's not what the eyes meant to say to the brain.
Think of it as a ghost image overlapping a new image. This creates a rippling effect called the moiré effect. When similar patterns are repeated and merged together, it changes your visual perception of the object. That's why your brain thinks the image is moving.
Researchers from the University of Hertfordshire have concluded that the concept of lying eyes is a myth.
The eye has limited frequency response, since it can only see electromagnetic radiation in the visible wavelengths. The eye distinguishes a new image multiple times a second, so it cannot be used to accumulate light over a long period in order to intensify a faint image.
“Obi-Wan Kenobi once said 'your eyes can deceive you, don't trust them. ' It seems to be getting harder. Distinguishing reality from the illusions people make for us, or the ones we make for ourselves.
An individual's eyes can reveal a lot about them, including their mood, feelings, and even emotions. By simply looking at them, eyes can convey a warm, bright, and inviting vibe as well as a cold and repellent one – they are the window to a person's soul.

What is the general problem with the eye?
The leading causes of blindness and low vision in the United States are primarily age-related eye diseases such as age-related macular degeneration, cataract, diabetic retinopathy, and glaucoma. Other common eye disorders include amblyopia and strabismus.
Often referred to as the reflection of the mind, eyes give an idea of a person's thoughts and feelings. Moreover, the shape of eyes also contain clues to personality traits. People with such eyes are likely to have a broad mind and are willing to accept different viewpoints. They will also be keen to help other people.
Eyes soften in love, harden with anger, widen in fear, narrow in suspicion, roll in exasperation, glaze with boredom, and weep in sadness. Experimental research with microphotography examining pupil dilation, blinking, and tearing might indicate if someone is lying.
