Optical Illusion
An optical illusion occurs when our brain interprets visual information in a way that deviates from reality, causing us to perceive something that isn’t actually there or perceive something in a distorted manner. These illusions happen because of the way our eyes and brain process images.
For example, an object might appear to change size, color, or shape based on the surrounding context or the way light interacts with it. Some optical illusions exploit the brain's tendency to make assumptions based on past experiences, leading to misinterpretation. They often play with depth perception, color contrasts, and shapes, causing our visual system to interpret stimuli in unexpected ways, making them fun and sometimes puzzling to figure out.

Optical Illusion IQ Test: Are You A Genius? Within 6 Seconds Spot The Inverted 18 among Inverted 81s - Solution
In this optical illusion, you are tasked with spotting the inverted "18" hidden among several inverted "81"s. The grid is filled with these numbers, which at first glance appear uniform, making it difficult to identify the difference. However, upon closer inspection, you'll notice that one "18" is flipped, while all others are "81"s in the same orientation.
The "18" is located near the bottom left corner of the grid, and the challenge lies in quickly discerning this subtle difference. This illusion tests your ability to focus on small details and enhances your visual perception, requiring sharp attention to detect the outlier among the seemingly identical numbers.
