While they can be rather difficult to solve, brain teasers are a fun and exciting way to test the efficiency of your puzzle-solving skills.
A newly surfaced puzzle, which determines the sharpness of your eyesight, has left people scratching their heads as they attempt to solve it.
Allegedly only those with the sharpest vision can spot the hidden word in this tricky word search.
Although the task may not seem too difficult, you've got less than nine seconds to attempt the puzzle, which will decide whether you have eagle-like senses.
The word search, which is created by Jargan Josh, shows a jumble of letters within the grid of 16 columns and 14 rows, but your task is to find the word "pathologist".
If you're able to find the 11-letter word "pathologist" in the given time frame then the creator considers you to be a "highly attentive individual".
According to the website, the brainteaser is ranked "moderate-level challenge".
It says: "Individuals with good observation skills will be able to spot the word within the time limit."
"The way the letters in the grid are arranged makes it difficult to identify at first glance."
Don't worry if you weren't able to spot the answer as we've labelled it clearly for you below.

The word "pathologist" was written backwards and cleverly hidden in the second column of the word search.
