ETDRS Chart
Standardized ETDRS Vision Testing Across Multiple Distances
The Huvitz HDC-100 ensures accurate and consistent visual acuity measurements through fully standardized ETDRS charts calibrated for multiple testing distances. Each chart maintains precise scaling and uniform letter size reduction using the LogMAR system, allowing eye care professionals to obtain decimal-level accuracy and enhanced reliability in vision assessments.
Low Vision 0.03/0.05/0.08
Specialized Test Charts for Low-Vision Patients
The Huvitz HDC-100 is designed to support accurate assessments for patients with low visual acuity, offering chart levels of 0.03, 0.05, and 0.08 for precise measurement when standard charts are insufficient. This advanced functionality enables eye care professionals to perform detailed low-vision evaluations, ensuring optimal diagnostic accuracy for every patient.
Black & White Reversed Chart
Black & White Inverted Charts for LASIK Patients
The Huvitz HDC-100 provides black-and-white inverted charts specifically designed to evaluate contrast sensitivity and visual performance in LASIK patients. By minimizing glare and enhancing contrast perception, these charts enable more precise and reliable post-surgical vision assessments.
Random Chart
Randomized Test Charts for Reliable Vision Assessment
The Huvitz HDC-100 features randomized chart sequencing to prevent patient memorization and ensure more objective test results. During repeated examinations, charts of identical size appear in different randomized combinations, enhancing test reliability and diagnostic accuracy for consistent visual performance evaluation.
10-Step Brightness Control
10-Level Contrast Adjustment for Advanced Vision Analysis
The Huvitz HDC-100 offers a 10-level contrast control, ranging from 100% to 1.5%, enabling precise contrast sensitivity testing and postoperative vision assessment. This feature provides clinicians with enhanced flexibility to evaluate subtle visual performance differences, particularly useful for patients recovering from ophthalmic or refractive surgery.
User-Centered Vision Testing Environment Enhanced for Convenience
Screen Portrait
Adjustable Testing Distance and Vertical Display Mode
The Huvitz HDC-100 provides customizable testing distances ranging from 1.5 m to 8 m, adjustable in 0.1 m increments, ensuring optimal flexibility across different clinical environments. Supporting both horizontal and vertical display modes, this system seamlessly adapts to a variety of exam room layouts and testing conditions, enhancing usability and workflow efficiency for practitioners.
HDR Series Networking
Playback of Educational Images and Videos
