Everything about Peripheral defocus
Peripheral defocus is the optical blur that occurs in the peripheral retina of the eye. It is an important factor in eye development and the progression of near-sightedness (myopia). In an uncorrected myopic eye, the central image focuses in front of the retina, while parts of the peripheral image may focus behind it, creating a relative hyperopic shift in the periphery. When light in the peripheral retina focuses behind the retina, myopia is more likely to develop or worsen. Conversely, when peripheral light focuses in front of the retina, eye growth tends to slow down. Wikipedia →
