Near Work–Induced Contrast Adaptation in Emmetropic and Myopic Children

“…10 There is evidence that the eye growth process is guided by a feedback system involving the visual signal quality (reviewed in Wildsoet 11 and Wallman and Winawer 12 ). A good quality visual signal, made up of a variety of spatial frequencies and contrasts, [13][14][15] is critical for normal visual development. Eyes experiencing poor retinal images induced by diffusers or minus lenses have excessive growth and become myopic.…”

“…Eyes experiencing poor retinal images induced by diffusers or minus lenses have excessive growth and become myopic. 12,[15][16][17] Reading involves looking at high-contrast text 12 at near for prolonged periods of time. Spatial frequency and contrast content may be limited, and this may be exacerbated by contrast and spatial adaptations.…”

Ocular Aberrations and Image Quality, Contact Lens and MYOPIA Progression

“…[1][2][3] Local retinal mechanism refers to a condition that local retina could minimize the image degradation on the corresponding retinal location by changing the axial eye growth rate. [4] The homeostatic control signals of the eyes growth try to keep the image sharply focused on the retina ("grow to clarity" model). [5] If the eye is in myopic status, the image of a distant object falls in front of the retina and if the eye is hyperopic, the image falls behind the retina.…”

Retinal cell imaging in myopic chickens using adaptive optics multiphoton microscopy

“…As typically found, fellow control eyes exposed to normal vision remained nearemmetropic (1.3 ± 1.6 D). The animals (4 week-old) were sacrificed with an overdose of ethyl ether anesthesia (see further details on [34]) and the ocular globes were immediately excised. After cutting the ocular globe along the horizontal plane behind the scleral ossicles, the vitreous was extracted and the retina detached from the fundus.…”
