Outstanding Features 45 Integrated Examination Charts The system includes 45 charts for visual acuity, refraction, binocular vision, color vision, astigmatism assessment, and amblyopia-related functions. Multiple Optotype Options Available charts include Landolt C, tumbling E, letters, numbers, and children’s optotypes, allowing the practitioner to adapt the examination to different patients. Adjustable Testing Distance The examination distance can be configured from 2.0 to 7.0 meters in precise 0.1-meter increments, supporting rooms of different sizes. Single Optotype, Row, and Column Isolation The practitioner can display a complete chart or isolate an individual optotype, horizontal line, or vertical column, reducing visual crowding and improving control of the examination sequence. Binocular and Refraction Testing Integrated functions include red/green testing, polarized binocular balance, astigmatism charts, and other specialized targets used during subjective refraction and binocular vision assessments. Color Vision Testing Dedicated color vision and color-deficiency charts can be selected directly from the remote control for convenient screening during routine examinations. Amblyopia Training Function The system includes a dedicated amblyopia training mode, providing an additional visual function for applicable professional workflows. Convenient Remote-Control Operation The included remote control provides direct access to chart selection, optotype isolation, red/green functions, system settings, chart navigation, and power control. High-Resolution TFT Display The 21-inch TFT LCD screen provides a resolution of 1440 × 900 pixels, a small pixel pitch, and high contrast for clear chart presentation. Adjustable Display Parameters The settings menu provides access to brightness, contrast, visual acuity notation, RGB values, language, operating mode, working distance, screen settings, and factory reset. Desktop or Wall-Mounted Installation The monitor can be installed on a compatible desktop base or mounted directly on a wall using the included hardware, providing flexibility for different examination-room layouts.
