Arm && Interventions

Group	Intervention	Description
Non-complaining group	mfERG (multifocal-retinogram)	the students in this group are not complaining of CVS symptoms but will be examined to diagnose CVS or exclude it
Complaining group	mfERG (multifocal-retinogram)	the students in this group are complaining of CVS symptoms but will be examined to document their complains and correlate to clinical findings

Primary Outcome Measures

Name	Time	Method
visual acuity	1 month	visual changes i.e. uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) using logMAR measurements following reduction of screen time
near vision	1 month	near vision changes following reduction of screen hours using card test, near visual acuity chart and near point test while the measurements will be diopters and lines of near chart
