Are your eyes playing tricks on you!?

The Chubb illusion is an optical illusion wherein the apparent brightness (luminosity) of an object varies dramatically, depending on the context of the presentation. For instance, a dark object surrounded by darker objects may appear brighter than an actually brighter object, surrounded by even brighter objects.

The Hermann grid illusion produces the illusion that there are gray spots or squares at the intersections of the streets or canals.
