@CSIC features #PLOSONE article on internal code of blur in an institutional Press Release



The Press Office at CSIC highlights our recent publication on how the eye is adapted to their own high order aberrations: “Each person has an internal code for the perception of best perceived images”

A classification-images based psychophysical test reveals internal code for blur, published in #PLOSONE


The eye appears adapted to the orientation of the native high order aberration. For the first time, using a classification-images inspired psychophysical paradigm, the orientation of the best perceived blur by subjects has been reveals, matching the orientation of the optical blur. The study, a collaboration between the Visual Optics and Biophotonics Lab and Peli’s lab at the Schepens Eye Research Institute-MEEI (Harvard University) has just been published in PLOS One.

Evaluating static and dynamic accommodation with high speed quantitative OCT, published today in BOE


OCT was used to quantify biometric and lens shape changes with accommodation in human eyes in vivo, from 3-D static  and from 2-D dynamic measurements. The geometrical contributions to the accommodative response and fluctuations of accommodation were also estimated. This study represents the first fully OCT-based quantitative assessment of real time accommodation.

The study was performed in collaboration with Maciej Wojtkowski’s lab at Copernicus University.
