Most of us use our eyes on an ongoing basis to decipher the world around us and to lead us through difficult times. If you don’t use your eyes to the full extent possible, however, you may be missing out.

There are many tests you can take that will allow you to see how good your visual sense is. These tests will also provide an opportunity for you to strengthen your visual acuity as well.

In some ways, you are dealing with optical illusions that trick the mind. Although it is not fully understood, it is thought that the eyes are sending too much information to the brain when we look at such an image.

This is the case with an image that has been circulating online recently. It has been said that only 1% of everyone who sees the picture is able to solve it.

The image itself uses something that is known as the McCollough effect. It uses a series of lines to trick the mind into seeing something that isn’t there or not seeing something that is there.

After you stare at the image for a few minutes, you may have an opportunity to see something that didn’t exist at first. In addition, there are ways that you can reduce the effect and make it easier to see.

One way to do so is to turn your head to the side 90°. You can do something similar by reversing or rotating the image.

What you are actually seeing is an afterimage because you are removing the stimulus yet still using your sense of sight. Scientists claim that it has to do with the activation of our visual system.

In addition, strong colors will make an impression on the visual system that sticks around. This is something that often happens when a flash from a camera stays with us for an extended amount of time.

According to the Journal of Experimental Psychology, you can experience this effect for up to three months if you stare at the color gratings for a long time.

If you would like to test this for yourself, you can do so with these images. They won’t hurt you, it’s just a simple and enjoyable test.

The two images stimulate the effect by staring at the center for a few minutes and then going back and forth between the pictures. When you look at the image to see red, green, or pinks that may not have existed before.

This is a fun test but there may also be an effect that is harmful. It involves staring at images of horizontal and vertical lines that might make you see a different color during the day. Some people who tried it have claimed to have a mixed reaction. Some had a headache.
