Portable Brain Wave Refractometer

Abstract

In this paper we demonstrate a new technique in which we use the Portable Brain Wave Refractometer (PBWR) to rapidly and accurately measure the error of refraction of eye. The aim of this study is to evaluate PBWR as a minimally invasive method of measuring the attention, meditation levels and the error of refraction of myoptic vision. Two psychologically-based tests were conducted to assess the suitability of the brain wave device to measure and categorize a user's level of attention and meditation. The two states of brain wave represent the normal or abnormal visions. The electroencephalography (EEG) lies in the mobile recording and real time feedback of emotional and cognitive states. This fast testing method for correcting the error of refraction of myopic vision can get the visual acuity (V.A.) to 0.8-1.2.
