We all know the basics about taking care of your eyes - like keeping certain substances out of them - but one specific issue has been on the internet's eyesight agenda this week.

In the aftermath of the eclipse which plunged the United States into a brief moment of darkness earlier this week, many people have been left wondering if they've damaged their eyes by looking directly at the sun without suitable protection.

As a result, this simple at-home eye test has been doing the rounds online.

It involves staring at an optical illusion-type square grid and it designed to provide you with an idea about the state of your eyes before you rush off to an optician's in a panic.

Starting to worry about your eyesight and fancy giving it a go? Let's do it.

To use it, cover one eye up and stare at the dot right in the center of the grid - then repeat with the other eye.

This mind-blowing optical illusion which reflects objects as different shapes will leave you baffled

If any of the lines are missing or become wavy, or if you notice any other unusual differences such as dark areas, strangely sized boxes, or blurry edges, you know something is up.

The earlier you diagnose any problems, the better position you'll be in to help your issues.
