Announcing a Technological Breakthrough for Testing Visual Acuity...

Advanced Refraction Equipment - the Stimuli^TMVisual Acuity System

• Randomizes optotypes and eliminates patient memory effect.
• Calibrates for long, short, or folded exam rooms.
• Wide Dynamic Range, High Sensitivity
• Offers pediatric patients special video and fixation targets.
• Resolves to Sub-pixel accuracy.

The Stimuli™

The Stimuli™ is a refraction device that replaces the old technology, the automated projector. Stimuli™ eliminates the "memore effect" by bringing virtually unlimited charts to the patient in a random manner. All functions are at the practitioners' fingertips.

All-Inclusive Computerized Projection System

The Stimuli™ System includes the Apple iMac computer with built-in monitor, Stimuli™ Software and the hand controller.

Adaptable to Your Requirements

All Stimuli™ units can be calibrated from long, short, or folded examination rooms for direct or mirrored viewing. Chart information can be graphical, via on-screen display, or audible via verbal line read-out. Stimuli™ features automatic daily start-up and shutdown.

Exceptional Capabilities

The Stimuli™ supports many types of acuity charts, optotypes, associated vision tests and fixation devices in a simple remote controlled unit. The Stimuli™ system offers more than 16 major selectable features, including LogMar, Snellen or Decimal units. An internal CD player may be utilized for room background music.

Intuitive, Wireless Hand Control

The buttons are grouped in a logical layout with the most commonly used buttons grouped in a circular pattern around a single button in the middle. The controller allows the practitioner to remain in eye contact with the patient while conducting the examination and selecting one of the features.

Available Tests

Upon initial start-up, the first test is the multi-line acuity chart. Other available charts include:

• Red/Green that can be isolated and reversed
• Unique sizable 4-dot
• Fixation test on black or white screen
• Astigmatic dial with controllable indicator and time and date charts. Once a chart is selected, the different optotypes can be changed

Excellent for Examining Pediatric Patients

In addition to standard pediatric animals that never require repair, a Stimuli™ Pediatric version is available with a suite of appealing optotypes-tumbling E's and C's, cartoons and tests.
