Measurement may be through the use of an eye fixed chart invented by Ferdinand Monoyer, by optical instruments, or by computerized tests just like the FrACT. In the expression 6/x imaginative and prescient, the numerator is the distance in metres between the topic and the chart and the denominator the gap at which a person with 6/6 acuity would discern the identical optotype.
