Criterium van Sheard
• Compensatie heteroforie
• Voorspellend bij exo’s
Criterium van Percival
• Comfort zone
• Voorspellend bij eso’s
Invloed van refractie op oogstand:
• AC/A gradiënt methode
• AC/A heteroforie methode
Computer Vision Syndroom (CVS)
Computer vision syndroom: asthenope klachten bij beeldschermwerk.
De prevalentie oogklachten bij beeldscherm werk is ongeveer 40% van de populatie met serieuze
klachten.
De asthenope klachten ontstaan na visueel inspannend werk en bestaan uit:
• Vermoeide ogen
• Irritatie
• Branderig gevoel
• Rode ogen
• Hoofdpijn
• Wazig zien op scherm
• Wazig zien na werk
• Bewegend of dubbel beeld
Waarom oogklachten?
