THIS stunning optical illusion shows horses on top of a mountain, but users struggle to see how many there are.
Bev Doolitte’s portrait of five ragged-skinned horses standing together on a snowy ledge has been a mainstay on the government’s website for years.

But scientists from the National Institute of Environmental Health Services claim that there are seven horses in the photo – not five.
What appear to be four white and brown horses and a foal are grouped together and blend into the brown rocks and snowy background, giving the image an optical illusion.
According to a group of NIEHS scientists, the painting was made of seven horses, including some partial horses such as the horse’s head and rump.
One of the scientists said: “I see one on the left side looking out, and in the middle four faces are grouped close together – in that group the brown nose of one (second from the left) covers the right side of the face of the one crouching lowest.
“On the right is a small horse standing sideways, and above it is the last part of the seventh. Unless I’m hallucinating.”
But some claim that if you can spot all five horses, you have perfect eyesight.
While you’re looking through photos to find boring ungulates, why not try some of our other optical illusions?
If you can spot a tiger in our freeze frame image in less than 10 seconds, you may only have 20/20 vision.
Earlier this week, The Sun challenged its readers to spot a hidden dog inside an optical illusion in less than 15 seconds.
But if you like something different and a little more challenging, try spotting all four faces in this stunning vintage flower picture.
