  • What Is LogMAR Visual Acuity and How Is It Measured?

  • What Is the LogMAR Chart? Definition, Research Vision Testing . . .
    Learn what the LogMAR Chart is Discover why this logarithmic test is the gold standard for medical research, how a score of 0 0 equals 20 20 vision, and why it provides more accurate data than Snellen
  • Measuring Acuity: LogMAR and Snellen Charts Explained
    LogMAR stands for logarithm of the minimum angle of resolution Developed in Australia in 1976, a LogMAR chart also has lines of letters, but each line contains the same number of letters and the spacing is standardized to minimize crowding effects
