It provides series of Landolt Ring Optotype under different condition routines - daylight, twilight with/without glare. |
|
The system realizing the optotype by a unique method that enable to minimize the degradation of optotype. 2 ranges of optotype indication is available by switching as
NORM 1.0logMAR to -0.1logMAR 12degrees
WIDE 1.3logMAR to -0.1logMAR 15degrees |
|
The Machine provides Automated process for the test routine associated with beep sound guidance. |
