Huvitz Carta de acuidade visual HDC-100

Over 100 standard optotypes
The Huvitz HDC-100 Digital Chart offers a versatile library of over 100 optotypes, enabling accurate and efficient visual assessments in a variety of clinical settings. Designed to meet the needs of eye care professionals, it includes English, numerical, Landolt C, and Snellen optotypes, as well as child-friendly image optotypes—ensuring comprehensive testing for patients of all ages.

Standardized ETDRS vision test at multiple distances
The Huvitz HDC-100 ensures accurate and consistent visual acuity measurements using fully standardized and calibrated ETDRS optotypes for multiple testing distances. Each optotype maintains precise scaling and uniform letter size reduction using the LogMAR system, allowing professionals to achieve decimal-level accuracy and greater reliability in visual assessments.

Specialized optotypes for patients with low vision.
The Huvitz HDC-100 was designed to support accurate assessments in patients with low visual acuity, offering optotype levels of 0.03, 0.05, and 0.08 for precise measurements when standard optotypes are insufficient. This advanced functionality allows professionals to perform detailed low vision assessments, ensuring optimal diagnostic accuracy for each patient.

Inverted black and white optotypes for LASIK patients.
The Huvitz HDC-100 provides inverted black and white optotypes, specifically designed to assess contrast sensitivity and visual performance in patients undergoing LASIK. By minimizing glare and improving contrast perception, these optotypes allow for more accurate and reliable post-surgical visual assessments.

Randomized optotypes for reliable visual assessment
The Huvitz HDC-100 features random optotype sequencing to prevent patient memorization and ensure more objective results. During repeated examinations, optotypes of the same size appear in different random combinations, increasing test reliability and diagnostic accuracy for a consistent assessment of visual performance.

10-level contrast adjustment for advanced visual analysis.
The Huvitz HDC-100 offers 10 levels of contrast control, ranging from 100% to 1.5%, allowing for precise contrast sensitivity testing and postoperative visual assessment. This feature provides greater flexibility for professionals to evaluate subtle differences in visual performance, especially useful for patients recovering from ophthalmic or refractive surgeries.

Adjustable test distance and vertical display mode.
The Huvitz HDC-100 offers customizable testing distances ranging from 1.5 m to 8 m, adjustable in 0.1 m increments, ensuring optimal flexibility in different clinical environments. Compatible with both horizontal and vertical display modes, the system easily adapts to various exam room layouts and testing conditions, improving usability and workflow efficiency.

Reproduction of educational images and videos
The Huvitz HDC-100 allows the display of sample images and videos illustrating various refractive errors, including myopia, hyperopia, and astigmatism. This feature improves patient understanding and supports clinical education during consultations. Additionally, users can easily play customized videos or display images directly from a USB device, offering greater versatility for personalized demonstrations and clinic visual identity.
