24 Mar Online Optical Illusion Based on Size
Psychological Articles Explaining Online Optical Illusions
In the wide range of online optical illusions available on the Web, many of them are based on the relative size of the visual elements in a visual frame. The perception of the visual elements is not an independent action. We perceive a visual element in connection with other visual elements. The same is true for online optical illusions. Psychological and Neuropsychological articles suggest that an object appears larger when placed with smaller objects and vice versa. This phenomenon has been incorporated into online optical illusions and has fun, amazing effects.
Comparison of Two Circles
Comparisons of geometrical figures are very popular online optical illusions found on the Web.
Figure 1 shows an online optical illusion that compares two circles surrounded by circles of different size.
Figure 1
In this online optical illusion, black circles of smaller sizes surround one white circle while bigger black circles surround another circle. When we look at this online optical illusion, the white circle surrounded by smaller back circles looks bigger than the circle surrounded by bigger black circles. But, are you sure that the size of these white circles are different? You will be surprised to know that these circles are actually same in size. Is it hard to believe? Then, draw a diameter of each of these circles and measure the length. You will find that your eyes are deceiving you. The truth is they are the same size.
The same effect holds true in other geometrical figures as well.
Comparison of two lines
Figure 2 shows an online optical illusion with two vertical lines of same size. However, when you look at this image, your brain perceives the vertical line on the right to be longer. It is due to the smaller space within the two horizontal lines as compared to that of the vertical line in the left.

This visual effect is used in many online optical illusions to trick the human eye. You can also easily create an online optical illusion of your own using this visual effect.
