# Raw\_datasheet\_RT_LED_M_V2.xlsx

describes the data obtained in two different levels of background luminance in three conditions 

### Description of the data and file structure

There are four Excel sheets.

The first sheet contains the personal data obtained for each middle age subjects followed by questionaries.

The second one Excel sheet contains visual reaction time in milisecond in different conditions for middle-age subjects

The third Excel contains the personal data obtained for each control subjects followed by questionaries.

The fourth Excel sheet contains visual reaction time in milisecond in different conditions for control subjects
