The HDC-9000N/PF features a user-friendly menu structure and special visual functions testing.
Various Types of Standard Visual Acuity Charts
The more than 100 various charts for the HDC-9000N/PF support all manners of tests for the visual acuity and visual function. Standard charts include tests such as Letter, Number, Landolt C, Snellen E, Children chart and other specialty charts as well.
Polarized Charts and Functional Charts
HDC-9000N/PF provides a variety of polarized charts that can be applied to many types of tests using the Cross Cylinder, Red/Green, Polarization and other special lenses such as the Binocular Vision Test, tereoscopic Vision Test, Heterophoria / Heterotropia Test, Binocular Balance Test, Fusion and Suppression Test, Aniseikonia Test and more.
Smart Display Function
The HDC-9000N/PF provides single letter and horizontal / vertical line masking with the image always displayed in the center of the screen. This function prevents test errors caused by memorizing the position of characters in advance by patients.
HDC-9000N/PF offers the ETDRS acuity at various test distances and a wide variety of ETDRS LogMAR tests are also available. (ETDRS acuity testing has become the worldwide standard for visual acuity testing replacing the Snellen and Sloan acuity tests.)
Color Vision Test
HDC-9000N/PF presents 12 charts for testing Color Blindness and 9 charts for classifying the level of visual inability
The improved effect for the visual function can be expected by measuring the convergence and divergence power as it helps the eye move through the vergence chart.
Contrast Sensitivity Test
The HDC-9000N/PF also has a function to measure contrast sensitivity at various levels using letter charts and the bar. The results of tests are analyzed and displayed providing the patient with more details and a professional and analytical diagnosis.
For the color blindness test, the HDC-9000N/PF supports the professional test consisting of 85 color charts diversified by wavelength and the simple test of 15 color charts.
Dynamic Visual Acuity Test
HDC-9000N/PF supports the high quality dynamic visual acuity testing with ocular pursuit training and saccadic eye movement training.
Stereoscopic Vision Test
Various types of Stereoscopic vision testing charts provide standards for deficiency diagnosis.
Amsler Grid Test
The macular degeneration can be checked by the amsler grid on the HDC-9000N/PF.
Playing Video and Image Slide Function
