The Distribution of Spatial Contrast in Manmade Environments Produces Regional Visual Form Deprivation

Widespread eFD is potentially experienced across the visual field in manmade environments. The extensive peripheral eFD and diminished contrast complexity of manmade environments suggest that gaze-limiting activities such as reading or using a mobile phone result in extended periods of peripheral eFD, which may contribute to myopia development. Therefore, enhancing the distribution of contrast in artificial environments to limit regional eFD may serve to prevent myopia onset.
