Eye Trainer Guide: Visual Tracking Practice Tool

Eye Trainer is a free browser tool for visual tracking practice. Use the guide to choose a mode, open a pattern URL, adjust the target, and keep the safety limits clear.

Motion patterns, no big claims

The patterns are simple screen paths. Pick one, adjust the target, and use the app for a short practice session.

Keep the safety line clear

This is practice software, not medical care. Stop if you feel eye strain, dizziness, headache, nausea, or any other discomfort.

Controls

Useful settings
