Optical illusions have gained a lot of popularity recently, as they get our brain to exercise, and can be the perfect test of our observational skills and keen eye. People who want to use their free time effectively can solve puzzles, which provide both entertainment and problem-solving solutions. The brain creates visual illusions through its incorrect processing of what the eyes detect during visual perception. It occurs when the information sent by the eyes conflicts with how the brain processes, and understands what it sees. Our brains create false perceptions through these illusions, which make us see things that do not exist while they distort the actual appearance of objects. The human eye perceives motion through visual processing which makes stationary pictures seem to move, and two identical objects appear to have different dimensions.Find the caterpillarA user named rastroboy shared this photo on the subreddit Find the Sniper. It shows a close-up of a flower, with the center and petals clearly visible in fine detail. In the middle of the bud, there is a brown object hanging down. Hidden somewhere in the image is a caterpillar.The caterpillar is extremely well camouflaged and looks just like part of the flower. Its natural coloring makes it almost invisible against the flower’s center. Your job is to find the caterpillar in 10 seconds Hint: Focus your eyes on the very center of the photo.The revealThe caterpillar is right in the middle of the picture. That brown thing sitting on top of the flower’s center, slightly to the left, is actually the caterpillar. Many users managed to spot it once they looked closely at that spot.One user said, “I think that’s a Synchlora Moth Caterpillar clinging to the plant’ left side.” Another said that it was, “on the left edge of the seed head.”Types of optical illusionsThe human brain experiences three main categories of optical illusionsLiteral Illusions: The brain creates non-existent images through its process of uniting different elements from an image. The way we view an image, can make it appear as either two faces or a vase.Physiological Illusions: The visual system becomes overactive because of excessive light exposure, excessive movement and color stimulation. The visual effects they produce include both afterimage appearances and moving objects, that seem to move.Cognitive Illusions: These rely on how the brain subconsciously interprets information. The Müller-Lyer illusion represents one example of an illusion which makes lines appear longer or shorter based on surrounding shapes.
