Map Level on the left side in window is the aberration value of wavefront, and it is the
color table to draw map. The max and min value of the aberration of measured
wavefront is indicated by the unit of micrometer(um). The wavefront aberration of
emmetropes is 0, and the severer the myopia and hypermetropia is, it is to have higher
wavefront aberration of (+) and (-) sign respectively.
By using the color table defined in Map Level, the map in the center of window is to be
drawn according to the areal wavefron aberration(refractive power) within pupil area.
Emmetropes is as in green, hypermetropia is as in blue, and myopia is indicated as in
red: the severer the abnormality of eye is, the thicker their colors become. In case
including astigmatism, the refractive power topography of oval type is to be drawn to the
direction of astigmatic axis.
