Dynamic Behavior of Human Eye
نویسندگان
چکیده
This paper presents novel details on the dynamic behavior of human eyes (see Fig. 1). A high speed camera is used to capture the movement of the eye surface, which is excited by an air jet. For a group of subjects the dynamic response ends shortly after the excitation is over. For another group of subjects this first phase ends with a distinct offset in the displacement, which takes a significantly longer time to vanish. The two distinct phases are the result of dynamic response of the cornea and the total eye, respectively. Understanding this eye dynamic is an important step towards the increase in reliability of diagnostic tools for glaucoma.

متن کاملStudy of Optical Models Regarding the Human Eye
Introduction: Until now, many models have been presented for optical study of the human eye. In recent years, surgery on the anterior section of the eye (such as cataract and photo-refractive surgery) has increased, so a study on the optics of the eye and evaluation of vision quality has become more important. Material and Methods: In this article, some of these models are considered. They incl...

Many people experience vibration effects on whole-body throughout their lives frequently. Vibrating energy absorbed is exposed all-body caused with vibration hazard in the vertically on body and biodynamic responses from body in speed 2.37 to 5.14 m/s could captivate with car seat on user body, so the vibration energy transferred to a seated people body. In this paper, the human body is modeled...
