Ever stared at an eye test chart and walked away with a result you didn't fully understand? You're not alone — and this guide is here to change that. Whether it's a Snellen, LogMAR, Jaeger, or Lea Symbols chart, each type measures something different, and knowing what they mean can make a real difference to how you manage your eye health. In this in-depth guide by Eye Q Eye Hospitals, you'll discover all six types of eye test charts used in modern ophthalmology, exactly what each one measures, and how to read your vision test results — including your prescription numbers (SPH, CYL, AXIS, and ADD) explained in plain everyday language. We also cover what 6/6 vision really means, how LogMAR scores work, when children need the Lea Symbols chart, and why a comprehensive eye exam goes far beyond what any chart alone can reveal. Whether it's your first eye test or your tenth, this guide gives you the clarity you deserve. Discover now — and start understanding your vision results like never before.
