The diversified defocus profile of the near-work environment and myopia development.

ABSTRACT:

Purpose

To quantify the defocus characteristics in the near-work environment at home and investigate the relationship with subsequent myopia progression.

Methods

Fifty subjects (aged 7-12 years) were recruited and followed for 1 year. The home near-work environment (writing desk) was measured at a baseline home-visit using the Kinect-for-Windows to capture a 3-dimensional image. The depth values of the image were then converted into scene defocus with respect to the subject's viewpoint. The defocus characteristics were quantified as the dioptric volume (the total amount of net defocus, or DV) and standard deviation of the defocus values (SD_D ). Information on home size, time spent outdoors, and in front of a desk were also obtained. Univariate correlation, and mul
