Optical illusion: Only a person with excellent eyesight can spot the lost glasses in less than 7 seconds

Ready for a quick challenge? This optical illusion is not just fun—it's also a great way to test how sharp your eyesight is!


A classroom full of students, all busy studying. A teacher is standing at the front, maybe explaining something on the board. The room is filled with school bags, books, water bottles, and of course, lots of chatter. But somewhere in this busy scene, a pair of glasses has gone missing. The twist? It’s right there in the picture—but so well hidden that most people miss it at first glance!


So here’s your challenge:

Can you find the lost glasses in less than 7 seconds?

Only people with excellent vision and good attention to detail can spot it that fast. Are you one of them?


Let’s take a closer look

In the image, you’ll see around 20 to 30 students sitting at their desks. Some are looking straight ahead, others are writing or talking to their neighbours. The teacher is in the front of the room, and the blackboard is filled with notes and diagrams.



At first, everything seems normal. But somewhere among the desks, notebooks, and faces, the glasses are hidden. It’s not placed out in the open. In fact, it’s hidden in the background. That’s what makes this illusion so tricky!


Why are optical illusions so interesting?

Optical illusions play tricks on our brains. They use patterns, shapes, and colours in clever ways to confuse our eyes. Our brain tries to make sense of what it sees, but sometimes, it takes the wrong path. This is why spotting the glasses becomes such a fun (and sometimes frustrating!) task.


But there’s more to it. Solving these illusions is actually good for your brain. Studies suggest that doing visual puzzles can improve focus, concentration, and even memory. It also gives your brain a mini workout, just like how running helps your muscles.


Still can’t find the glasses?

Don’t worry, you’re not alone. Many people take more than 30 seconds to find it. Some even give up! Here’s a small hint: Try scanning near the teacher’s desk. Don’t look at the obvious things. Look around them. Sometimes, the hidden item is right next to something that grabs all your attention.




Also, don’t just look at the centre of the image. Move your eyes around the edges too. Optical illusions often hide items near places you least expect—like behind an open book or even blending into someone’s hairstyle!
