Effect of Surrounding Blur on Foveal Visibility For those reasons, blur is an intrinsic feature of retinal images. Previous studies [ 1 — 5 ] have demonstrated that a certain period of exposure to the EIZO FlexScan T962 blur blur adaptation improves visual acuity, suggesting the presence of a neural circuit that compensates for blur. More recently, Artal et al. In addition, blur adaptation reportedly affects perceptual blur sensitivity [ 5 ] and judgment of focus [ 78 ]. In[…]
