About this study

CVS-F3 is a survey form consisted of up to 30 questions regarding Computer Vision Syndrome (CVS) complains, thereafter a randomized sample of students will be subjected to complete ophthalmic examination including visual acuity and refractive measurements, intraocular pressure measurements, Slitlamp and fungus examinations, mfERG examinations. the sudents will be requested to decrease their screen time and the examinations will be repeated one month later.

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • University students

Exclusion criteria

  • Amblyopia
  • Anisometropia
  • strabismus
  • Previous eye surgery

Treatment and study plan

mfERG (multifocal-retinogram)

Diagnostic Test

mfERG will be performed for the students to document the effect of CVS on retina

Primary outcomes

  1. visual acuity

    Time frame: 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

  2. near vision

    Time frame: 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
