“…Because Ocular organ region is very much near to the electrodes placed on the frontal region to acquire EEG [17]. Ocular potential is induced near and around the ocular region because the eye acts as a dipole where the cornea is more positive than the retina [13,19]. The episode of the blink takes place, when the eye lid slides over the cornea.…”

“…The episode of the blink takes place, when the eye lid slides over the cornea. In this episode eye lid picks up the potential from the positively charged cornea and imposed on to the nearby frontal electrodes of EEG which are placed near around Ocular region [19,21,22], equivalent is obtained in Eq. ( 2).…”

“…Due to firing of these neurons the electric potential induced over the scalp. This potential would be in an order of microvolt and millivolt when acquired using subdural electrodes [8,13,16,18,19,20]. Light is a transverse and electromagnetic wave that be experienced by the humans by perception of vision.…”

The influence of light on Electroencephalogram seems to be more critical, when physician depends on its readings to diagnose subject brain disorder according to its level. Although, bright light brings various changes in human physiological variables. But, Neurophysiological changes for specific light level still remain unclear. Thereby, in the present study, the response of brain electrical activity towards various light levels has been classified and verified. The reasons for alteration in different physiological variables due to bright light which results change in the state of electroencephalographic recordings has been reviewed. Additionally, the effects of bright light towards Ocular artifacts are also put forward. A novel hypothesis has been made using subjective analysis and experimental analysis in low luminance or darkness. It is observed that a poor lighting condition affects both behavioral task and brain activity.

“…The changes in light intensity which illuminate on to the human eye also reflect on electroencephalographic readings. [1][2][3] Optical powered glasses are used by people to correct refractive errors of an eye. These optical powered glasses help them to have clear vision and proper focus to perform any visual task.…”
