Prove you have 20/20 vision by finding the mouse and completing this brainteaser in under 12 seconds

Can you spot the mouse in this visual illusion within 12 seconds?

A new brainteaser is challenging people's cognitive abilities - if you can locate the tiny mouse concealed in the image within 12 seconds, you're said to have '20/20 vision'. This puzzle, a form of visual illusion, is particularly tricky - it's almost impossible to spot the mouse camouflaged amongst the mushrooms.

The image - a mix of different coloured mushrooms with a tiny mouse sneakily hidden among them - is designed to test cognitive function and visual perception. Neurological experts suggest that taking time for mental exercises, like regularly tackling brainteasers, can offer numerous cognitive benefits.

These benefits could potentially lower your risk of developing neurodivergent diseases, such as Alzheimer's, and protect against dementia. This mushroom-themed brainteaser has been posted on a brainteaser blog, offering a more challenging take on these types of visual perception puzzles.

This kind of brainteaser demands sustained attention, which helps train your brain to concentrate for longer periods - researchers believe that this type of mental exercise can also help improve focus in other areas of your life, reports the Mirror.

Having trouble spotting the mouse?

It's not an easy image to decipher. The best approach to solving this kind of visual puzzle is to divide the image into smaller sections, then concentrate on examining one area at a time.

This method of working through the image in sections can make locating the mouse somewhat easier. Granted, the solution to the puzzle is extremely well concealed, with the mouse blending seamlessly with the mushrooms.

However, if you focus on the middle-left section of the picture, you should be able to discern the mouse's head and ears protruding above a mushroom.
