Optical illusions never fail to amaze us.
With the use of colour, pattern and light, the mind can easily be tricked by what it sees.
Now the experts at contact lenses specialists Lenstore have shared a mind-boggling optical illusion which will trick your mind.
So are you ready for this one?
It’s asking people to stare at the cross for the dots to disappear.
Alternatively, follow the white dot around for 30 seconds to a minute until the grey dots appear green.
If you’re wondering why your vision goes all funny, there’s a simple explanation to it and it’s called the Troxler’s Fading.

Swiss physician Paul Troxler found that focusing your vision on one element can make all the other objects disappear or fade.
The effect happens when the optical illusion affects visual perception.
We’ve seen this happen before with the Pac-Man optical illusion as it baffled the internet.
Lenstore asks people to focus on the cross in the centre of the red circles popping in and out of sight.
You will find that the space in the red circles leave behind are replaced by green spot afterimages.
After a while, you might find that the red spots seem to disappear altogether (due to “Troxler’s Fading”).
If you look at the brainteaser, something very odd happens if you stare at it for 30 seconds.
When the image was posted on Reddit last year, many were baffled by how their vision changed.

Previously, another optical illusion confused people as it involved a parrot’s eye.
After the time is up, there is an afterimage which keeps appearing even after exposure to the original ends.
More specifically the parrot is a negative afterimage; and the colours are reversed from the original.
