Mix images of Tony Blair and Margaret Thatcher. Then, look at the images in different sizes to determine if you need glasses. The small images should be used to see Marilyn Monroe and Margaret Thatcher. As the photos grow, they will gradually become the ex-prime minister of the UK or the genius in physics. If the woman is still visible, it’s time to get checked out. You may need glasses, or you should have your existing ones adjusted. As your eyes adjust to larger images, the small Margaret Thatcher image should slowly become one of Tony Blair. Image: MIT. The same holds true for hybrid images. If you are far enough away from either of these images, you’ll see the female (Monroe) or Thatcher. As you move closer to the image, the picture will slowly turn into the male (Einstein and Blair) if you have good vision. What’s a hybrid image? An optical illusion is a hybrid image that can be perceived differently depending on the size and viewing distance. Philippe G. Schyns of University of Glasgow, Scotland and Aude Oliva of MIT (USA) developed a technique to create hybrid images that exhibit this optical illusion. This was described in 1994.. In the journal Art & Perception , Dr. Oliva discussed hybrid images. Dr. Oliva stated that hybrid images are a result of multi-scale image processing in the human visual systems. The smallest image will look more like Marilyn Monroe, while the biggest one should be like Albert Einstein. If you have perfect eyesight.

According to the Canadian presenters, “Depending on your ability to focus and pick up contrast, your eyes will only pick out specific details.” We can pick out fine details such as Einstein’s moustache or wrinkles up close. But, the closer we get, the less detail our eyes will be able to see. You see only the general features of Marilyn Monroe’s face, such as her nose, mouth and shape.
