Optical Illusion
An optical illusion is a fascinating visual phenomenon where the images we see deceive or trick our brain, making us perceive something differently from how it actually is.
These illusions play with shapes, colors, patterns, light, and perspective, creating effects where objects might appear distorted, hidden, moving, or even changing size.
Although our eyes capture the visual information, it’s our brain that interprets it and sometimes, it gets fooled by clever designs.
Optical illusions are not only entertaining and fun to solve, but they also help scientists and psychologists understand how human perception works, revealing the complex ways our brain processes visual information.

In this optical illusion IQ test, your task is to spot the number 3 hidden among numerous 8s within just 8 seconds. At first glance, the puzzle seems deceptively simple, but the challenge lies in how similar the shapes of 3 and 8 are.
Both have smooth, curved lines, making it easy for your eyes to mistake one for the other when scanning quickly. The brain naturally groups similar patterns, so it’s easy to overlook the subtle gap or difference that distinguishes a 3 from an 8.

Optical Illusion IQ Test: Are You A Genius? Within 8 Seconds Spot The Number 3 among 8 - Solution
In this optical illusion IQ test, the challenge was to spot the number 3 hidden among dozens of 8s within just 8 seconds. At first glance, the grid appears uniform because the shapes of the numbers 3 and 8 are quite similar, both featuring smooth curves that can easily fool the eye into thinking they’re identical.
However, on closer inspection, you can see that the number 3 is located toward the right side of the image, standing out once you notice the gap where the lower loop of the 8 is missing. In the picture, it’s helpfully highlighted with a red circle.
This puzzle is a great example of how subtle visual differences can challenge our perception, testing not just eyesight but also mental focus and attention to detail. If you spotted it quickly, congratulations you truly have a sharp eye!
