Compare images


Compare images The exercise 'Image Comparison' offers a more playful way to train your eyes. The task is to examine two almost identical images for their differences. Compare these two images by looking closely at the same areas with both eyes on the left and right. Since you don't know where the differences are hidden, you always have to look from one side to the other. Depending on the degree of difficulty, there are more or less differences to be found and the errors are easier or more difficult to find. With more than 10 different categories, you won't be bored.
