Total questions: 10
Worksheet time: 3mins
Which of the following is the most significant cause of accommodative dysfunction in prolonged digital device users?
Increased ambient illumination
Reduced blink rate
Constant near fixation distance
Spectral emission of blue light
The reduced blink rate during digital screen use is primarily associated with
Decreased corneal oxygenation
Increased tear film evaporation
Lagophthalmos
Decreased aqueous production
According to the American Optometric Association, the recommended maximum continuous screen time before taking a visual break is
10 minutes
20 minutes
30 minutes
40 minutes
Which of the following binocular vision findings is most commonly associated with Computer Vision Syndrome?
Divergence excess
Convergence insufficiency
Accommodative infacility
Intermittent exotropia
In patients with CVS, a higher near exophoria is commonly attributed to
Fatigue of the lateral rectus muscles
Reduced accommodative convergence
Poor fusional divergence reserves
Increased tonic convergence
Which parameter is least affected in computer vision syndrome?
Tear film breakup time (TBUT)
Meibomian gland function
Pupillary light reflex latency
Blink rate
Blue-light filtering lenses are believed to alleviate CVS symptoms primarily by
Enhancing contrast sensitivity
Reducing retinal phototoxicity and glare
Improving accommodative facility
Increasing pupillary constriction
The typical spectral peak of blue light emitted from LED screens that is implicated in digital eye strain is approximately
350–400 nm
400–450 nm
480–520 nm
520–580 nm
Which diagnostic test provides the most direct assessment of tear film instability in CVS patients?
Schirmer’s test
Meibography
TBUT
Tear osmolarity
