DISPLAYING THE MEASUREMENT RESULT
order aberrations, etc. are calculated. Description about the analysis
is given at the bottom part of the image. (Analysis center/Amount of
central movement (see page
104))
(5) Ocular Total Aberration map
A total aberration map, including lower order aberration of ocular
refraction. This map can distinguish near and far vision tendencies.
REF values are displayed at the bottom of the map.
For example, if the center of the map is cold in color (blue), near
vision tendency. If the center of the map is warm in color (red), far
vision tendency.
(6) Ocular HOA map A map to display ocular higher order aberration (e.g. irregular
astigma). This map displays irregular astigma which cannot be cor
-
rected by eyeglasses.
At the bottom part of the map, corneal higher order aberration, 4-mm
area and 6-mm area, are displayed with RMS values.
(7) Simulation Simulation of the target using ocular higherorder aberration.
Visions of target by 20/100 (0.2), 20/40 (0.5) and 20/20 (1.0) are dis-
played, from the top stage.
(8) Analysis center Whether the analysis center is the pupil center or the mechanical
center is shown. Also, the distance between pupil center and
mechanical center is displayed.
For details about the pupil center and the mechanical center, see
"
ANALYSIS CENTER" on page 104.)
Operation: • When tapped, the image is enlarged. (See "ENLARGEMENT DIS-
PLAY" on page 94.)
• When dragged in the right-left direction, the overlay can be
changed. (See page
98.)
Operation: • When tapped, the image is changed to the ocular aberration map.
(See page
81.)
• The map display step can be changed. (See "SETTING THE
TOTAL ABERRATION MAP DISPLAY STEP (TOTAL ABERRA-
TION MAP RANGE)" on page 146.)
Operation: • When tapped, the map is changed to the ocular aberration map.
(See page

TYPE SIMULATION 1 (UPPER)" on page 151.)
• To normalize the brightness or not can be changed. (See "SET-
TING THE NORMALIZATION OF BRIGHTNESS OF SIMULATION
(NORMALIZE DESTINY OF SIMULATIONS)" on page 152.)
