ABSTRACT
Background: In General, optical powered glasses are used to have good focus and clear vision. But, this practice may also bring noticeable variation in light intensity which in turn affects neural behavior. These changes can be interpreted from the EEG recordings. Thus, in this present study, the grounds for amendments in different physiological variables due to light intensity through optical glasses experienced by the subject have been reviewed and verified. Experiment: Changes in light intensity through optical powered glasses have been demonstrated using a Light Dependent Resistor (LDR) test for various cases. From this study, it was found that positive powered optical glass increases the light intensity falling on an eye, while negative powered optical glass reduces light intensity. Case Study: A case study was performed using experimental and subjective analysis were made to confirm that misfocused or unclear vision bring changes in frontal frequency and makes subject fatigue and eyes strain which is prone to severe headache and development of seizures. Recommendations: It is to be noted by the EEG practitioner to confirm that, whether optical powered glasses used by the subject is to be match with refractive error of an eye. If not, the frontal frequency gets increased and may suspect as seizures or other any abnormality.
