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. They are also super fun to solve, and can be the perfect recipe for a bored evening! An optical illusion is actually a visual phenomenon where the brain misinterprets what the eyes perceive. It occurs when the information sent by the eyes conflicts with how the brain processes and understands what it sees. These illusions often trick us into seeing things that are not there, or perceiving objects differently from reality. For example, a still image might appear to move, or two shapes may seem unequal in size even though they are identical.This brain‑teaser is a trick that tests one’s eyesight!This is an image of a battlefield‑themed tableau, decorated with everything, from rifles, rucksacks to helmets and, believe it or not, a tiny rubber duck, all set against a brown canvas! Not only that, there are two camouflaged bullets hidden somewhere, in the scene.The picture, posted in the r/FindTheSniper subreddit, by Redditor Maintenancelcy9958, presents a packed scene of gear. At first glance the assortment looks perfectly ordinary-rifles sit beside pouches, radios, flashlights, boots and other stationary equipment. However, hidden amidst the chaos are two bullets – their minuscule forms blending so seamlessly with the surrounding items, that they’re nearly impossible to spot on a casual look. However, can you spot them? Go ahead and give it a go, but remember, you just have 15 seconds to do so!The revealGive up? Here’s the answer. The first hidden bullet rests in the bottom‑left of the image, snug next to a rubber duck and a suppressor. Its pattern merges with the surrounding tan and green gear seamlessly, and anyone who doesn’t zoom in closely will miss it entirely. The second bullet lies up in the corner tucked near the batteries, and almost invisible, amid the clutter. When it finally comes into view, the clever camouflage of both bullets becomes obvious – a test of the observer’s eye.Types of optical illusionsThere are three main types of optical illusions:Literal Illusions: These occur when the brain combines elements of an image to create something that doesn’t exist. For example, an image might look like two faces or a vase depending on how you interpret it.Physiological Illusions: These are caused by overstimulation of the visual system, such as excessive exposure to light, movement, or color. They can create effects like afterimages or motion illusions.Cognitive Illusions: These rely on how the brain subconsciously interprets information. Examples include illusions like the Müller-Lyer illusion, where lines appear longer or shorter due to surrounding shapes.
