Visual Vertical Lite makes subjective visual vertical (SVV) testing simple and accessible using equipment you already have. Traditional SVV testing can require specialised equipment and a controlled visual environment. Visual Vertical Lite provides a practical alternative using your iPhone, a bucket and a small piece of Blu Tack. HOW IT WORKS Mount your iPhone inside the bottom of a bucket using Blu Tack. The person being tested holds the bucket to their face and adjusts the line on screen until it appears vertical. Visual Vertical Lite measures the resulting deviation from true vertical and displays the result in degrees. TEST THE WAY YOU NEED Choose from: • Left eye • Right eye • Both eyes open Visual Vertical Lite is designed for quick, individual measurements, making it ideal when you simply need to perform a one-off SVV test. SIMPLE RESULTS Results are presented immediately in a clean, easy-to-read format, including the measured deviation and direction. BUILT-IN GUIDANCE Not familiar with the bucket method? The included guide walks you through equipment setup, positioning, testing and interpretation of the results. LITE OR FULL? Visual Vertical Lite includes the core functionality required to perform individual SVV tests. For sequential testing, multiple readings and automatic averaging across test conditions, choose the full Visual Vertical app. UPDATED FOR MODERN iOS Visual Vertical Lite has been comprehensively updated with a redesigned interface, clearer navigation and support for current versions of iOS.
