YOU could have 20/20 vision if you can spot the hidden deer in this outdoor scene.

The tricky optical illusion has tested players as they only have seven seconds to spot the animal.

A brief TikTok video from Cody Smith (@american_sportsman_tv) has baffled viewers.

In the video, an outdoor shot from a nightcam can be seen.

Two raccoons can easily be spotted eating away at something on the ground but another animal is also in the shot.

Viewers however were challenged to spot the hidden deer and not the two raccoons.

“Only Pro Hunters can spot the deer,” the video’s voiceover said.

The camera shot also showed the trucks of several tall trees in the background and several small and bare shrubs.

Here is a hint if you need one.

Focus on the space between the trees on the left-hand side of the scene.

Some TikTokers also shared a useful tip in the video’s comments.

“U can see the eyes glow,” one person wrote.

If you were unable to find it in time do not worry as the answer is down below.

Why not try another brain teaser to really test your eyesight?

You could have the eyes of a hawk if you can spot the cleaning sponges among the dirty dishes.

Players have 20 seconds to spot five sponges in this image.

This image from Hiatt Hardware tests how far players can see past the dirty dishes.

Plates, glasses, and pans have piled in the sink and across the counter.

There was even a half-eaten watermelon and unfinished wine to look past.

Here is a clue for those who need one.

All of the sponges are yellow and green.

Here is a second hint.

One of the sponges could be drying on a rack, unlike the others.

The answer is down below for those who may have been unable to spot all five in time.
