Researching the accommodative mechanism of the human eye, including changes in the optical and physical properties of the human lens.


  • Gradient index model of the crystalline lens
  • Gradient index (GRIN) exact differential ray-tracing.
  • Etiology of presbyopia, myopia, lens paradox and age-related decline of human visual acuity.
