A The 1,0 line is easier to see than the 6/60 Snellen equivalent, B It allows for equivalence of target resolution requirement at varying working distances, C It is only available as a handheld chart as it is for use at different working distances, D logMAR charts all require a patient to know the alphabet. Customers love it because they are quick, short, and straightforward. Research has indicated that, while higher-order aberrations influence the amount of sphere and cylinder required to correct vision, subjective refraction can be predicted from the eyes optics alone by optimizing computed retinal image quality.7 Unfortunately, the data also showed that the range of predictability decreased with greater amounts of higher-order aberrations (e.g., higher RMS numbers). this.value = fields[0].value+'/'+fields[1].value+'/'+fields[2].value; 2011 Jul;27(7):509-17. doi: 10.3928/1081597X-20101214-01. A video clip introduction to the phoropter is provided on the website .
