Fun for the Eyes

I love optical illusions. I find it so very interesting that our brain can so easily misinterpret what our eyes see. In the picture below, you can see a black and orange line that spirals through the geometric shapes of triangles and diamonds.





Actually, if you will follow the line with your finger, you will find that each is a complete circle. There is no spiral!




This is another fun picture. Squares A and B are the same shade of gray.



I know that you may have a more diffucult time believing me on this one. Right click on the image and save it to your computer. Then open the image with Paint or other similar program. Then just cut out a piece of one and move it to the other square. Or you can print the image and then cut or fold the paper to prove it to yourself. The contrast of light and dark created by the shadow fools our brains into believing that B is lighter than A.


And then there are those that can draw what is an impossible reality.

Have a great day...but don't always trust your eyes!

It's unfair to post pictures like these in front of someone trying to cope with trifocal glasses at the same time. I hope my eyes uncross sometime soon. B.

Amazing illusions. We must remember that what we see isn't always the truth. Fun post!

it's amazing to see how illusion has tricked our brain and fooled us!
