Depending on customer’s preference, LCD-1000P uses Circular Polarisation as image separation for binocular testing; whereas LCD-1000 uses Red/Green image separation method. Circular Polarisation provides 100% image separation that prevents ‘ghost-image’, enhances readability, improves display contrast and reduces glare. Both LCD-1000P and LCD-1000 offer the same features.

Masking: It is possible to mask all Optotypes in horizontal row or vertical column or single character. The masked Optotype can either be displayed in its default position or in the screen middle position. Masking will be maintained when selecting the next Optotype chart.

Randomisation: All Optotype charts can be randomised when the chart is in full screen, masked (horizontal / vertical) or single character.

Reversed-Contrast - White on Black*: The LCD-1000(P) Optotype can be set to reversed-contrast where the screen background is black, as some practitioners may prefer to use this option on patients with specific needs. When using a white background, the brightness can be set to accommodate the room light condition.

Red / Green Filter: The Red/Green filter can be overlay on all Visual Acuity Optotype charts for quick assessment of monocular or binocular balance, * Only available in combination with RC.

Spatial Frequency Contrast Sensitivity test: The Spatial Frequency Contrast Sensitivity test is available in: • 4 Frequency (cycle per degree) and 5 Contrast levels (%) • 5 Frequency (cycle per degree) and 10 Contrast levels (%) The test results are graphically displayed and can be exported for further analysis.

Pseudoisochromatic colour vision test*: The LCD-1000(P) Pseudoisochromatic colour test charts provide colour perception examination to patients suffering from colour deficiency.

Crowded Optotype*: Optotype can be displayed in normal ‘grid’ format or ‘overcrowded’ format. You can isolate Single Optotype by using the 4 isolating bars.

Contrast test: Contrast Sensitivity test helps to determine what level of contrast a patient could detect for a given Optotype size. The LCD-1000(P) contrast level can varies from 100% ~ 6%.

Maddox White LED: The LCD-1000(P) uses an integrated white LED light for the Maddox test. The intensity of this LED light is adjustable up to 10 levels to suit customer’s preference. You can also use this LED light as patient’s fixation point.

* Only available in combination with RC

 LCD-1000(P) integration with DR-900 Digital Refractor: The LCD-1000(P) functions as a standalone system, using the designated remote control. LCD-1000(P) can also be used with Rexxam Digital Refractor DR-900 (via infrared connection) to function as an integrated refraction system.
