Great use of gestalt principle

I thought this was a good example of the use of gestalt principle. It gives off the message clearly. Since the message on the advertisement says "see more clearly", I like how the designer used a very clear background. One looking at the advertisement does not get lost while viewing it, but rather knows exactly what the advertisement is trying to represent. It is very clear, clean, and concise. I like how the designer made it clear that the picture was of a blue sky and green grass. The eye glasses in the middle draws attention to the viewer right away. This advertisement is an example of a great use of gestalt principles.
