Clinically Validated Assessment
This screening combines two validated clinical instruments: the Binocular Vision Dysfunction Questionnaire (BVDQ) and the Symptom Severity Index (SSI), both extensively used in research and clinical practice.
A threshold score of ≥15 on either measure suggests possible BVD and warrants comprehensive evaluation.
Who Should Take This Assessment?
This screening is designed for adults experiencing unexplained symptoms that may indicate binocular vision problems:
Persistent headaches
Dizziness or balance issues
Reading difficulties
Double or blurred vision
Light sensitivity
Anxiety in crowds
Step 1: Select Your Symptoms
All symptoms start as “Never”. Simply tap any symptom you experience. Once selected, use the slider to indicate how often it occurs: Occasionally, Frequently, or Always.
Step 2: Rate Symptom Severity
For each symptom category, indicate how bothersome it is from 0 (not bothersome) to 10 (extremely bothersome). Only tap symptoms that affect you.

Understanding Your Results
This screening is an educational tool and is not a diagnosis. Only a comprehensive eye examination by a qualified provider can diagnose binocular vision dysfunction.
