Vision Quality of Life with Time Survey (VisQuaL-T) Online Calculator

Vision problems can sometimes make dizziness worse. Reading, screens, busy places, driving, or visually demanding tasks may cause symptoms like dizziness, headache, eye strain, blurry vision, trouble focusing, or sleepiness. The VisQuaL-T asks how long someone can do certain activities before symptoms start. Your score does not give a diagnosis, but it can help show which visual activities may be harder to tolerate and help guide a conversation with a healthcare provider.

Why use the VisQuaL-T?

The Vision Quality of Life with Time Survey (VisQuaL-T) helps clinicians understand how long a patient can tolerate common visual activities before symptoms begin. This can provide useful context beyond vision or vestibular testing alone. The VisQuaL-T may be helpful when evaluating patients with dizziness, visual motion sensitivity, eye strain, headache, blurry vision, trouble focusing, screen intolerance, or symptoms that worsen with visually demanding tasks. It can also be used to track patient-reported change over time.

Common Clinical Uses

Clinicians may use the VisQuaL-T to:

Assess tolerance for visually demanding activities
Identify tasks that trigger dizziness, headache, eye strain, or blurry vision
Support baseline documentation and care planning
Guide treatment goals related to visual activity tolerance
Measure patient-reported change over time
Document functional progress during treatment

Score note: A higher score means symptoms tend to start later during these activities. The VisQuaL-T is a symptom survey and does not diagnose the cause of dizziness or vision symptoms.
