If you stare at a clock and the first tick takes longer you're not imagining it – there's a scientific reason why | The Sun

THE first tick on the second hand of a clock may appear to take longer for a wild scientific reason.

You can look at a clock faster than your brain can register what it's seeing, making that first second feel longer than it actually is.

Famous science YouTuber AsapSCIENCE created a video explaining the interesting concept.

"Do you ever look at a clock and feel like the first tick of the second hand actually last a bit longer than the rest?" the science lover said.

"There's actually a really cool reason that this happens, and you're not just imagining it."

The AsapSCIENCE host explained that your eyes have two modes of operation: smooth pursuit and saccades.

Smooth pursuit is when you slowly watch something that's moving while saccades is when you quickly jump from one point to another.

"When your eyes make that jump from point A to point B it happens so fast that your brain can't actually take in any information," the YouTuber said.

"So instead your brain takes the image from point B and backfills that missing gap with image B."

Therefore, when you take a look at a clock, your brain is telling you that you've been staring at it from the second you looked at the last object.

"And as a result, the first second actually looks and feels longer than all the others," AsapSCIENCE said.

This comes as this mind-blowing optical illusion may reveal something about your memories depending on what you see in the image.

Optical illusions utilize many factors to confuse the human brain, such as color and shape.

One TikTok user with the handle @CharlesMeriot illustrates this in a 15-second reel.

In the video, Charles displays a green and yellow image that can be perceived in two different ways.

Some people may see two crocodiles facing each other first, while others may see an eagle mid-flight.

"What did you see first," the TikTok content creator asked his viewers.

"If you saw the crocodiles first, it means you have a fierce personality, you're very aggressive but you're looking for a relationship right now," Charles said.

"If you saw the eagle first, it means that you're very proud, you embrace opportunity, and you'll step on other people if they get in your way," he added.

Ambiguous illusions play up light, color and shapes to trigger your optic impulses.

These optic impulses are then relayed through your optic nerve to your brain where it instantaneously begins to interpret information, experts at eye-care company Clear Eyes explained:

"This is where the disconnect occurs that 'tricks' your brain into seeing—or not seeing—what’s really there."

Memories and personal experiences also play a role in the interpretation of ambiguous image optical illusions, according to new studies.

"Think of your working memory as your mind’s eye—the little nuggets of data your brain retains for short periods of time," experts at Clear Eyes noted.

"While these memories may only be temporarily stored in your brain, they influence your perception."
