Technical Highlights & Why Choose the Ezer ETR-770
The Ezer ETR-770 combines advanced functionality with reliable performance, making it a smart investment for practices looking to modernize their workflow without expanding their physical space. It offers 33 chart types for both near and distance vision testing, supported by high-quality LED illumination that ensures clarity and consistency throughout every exam. The system features a wide range of connectivity options, including USB, LAN, RS232, Wi-Fi, and Bluetooth, allowing seamless integration with other diagnostic devices and digital practice systems. Operating on a universal power supply (AC 100–240V, 50/60Hz) with low power consumption of approximately 75W, the ETR-770 is both efficient and practical for daily use.
Beyond its technical capabilities, the ETR-770 stands out for its ability to transform clinical workflows. Its compact design, digital efficiency, and telemedicine readiness enable practices to reduce exam time, improve diagnostic accuracy, and expand access to care. By allowing remote refraction and flexible deployment across multiple locations, it enhances productivity while delivering a superior patient experience. Its versatility makes it ideal for optical stores, clinics, and modern eye care environments, positioning it as a future-ready solution in today’s evolving ophthalmic landscape.

All-in-One Compact Design
The ETR-770 has been carefully designed to consolidate multiple diagnostic functions into one compact workstation. By integrating the phoropter, chart system, and control interface into a single unit, it eliminates the need for bulky equipment and large exam rooms. This makes it particularly valuable for optical retailers, small clinics, and high-traffic environments where space optimization is critical. Despite its compact size, the system delivers a full professional refraction experience comparable to traditional setups.

Advanced Display & Control System
To ensure accurate diagnostics, the ETR-770 incorporates a high-resolution display system with LED illumination 5.7-inch color LCD touch screen. This provides clear, bright, and consistent visual output, allowing patients to easily identify optotypes and enabling practitioners to make precise assessments. The quality of the display enhances both the reliability of the exam and the overall patient experience, reinforcing confidence in the results.

Ergonomics play a key role in daily operation. The main control dial, equipped with an integrated S / C / A mode key, allows for quick and smooth adjustments of refractive values, enabling practitioners to work with precision and speed.

Sophisticated Digital Refractor
Engineered with a refined and modern ergonomic structure, this refractor enhances both comfort and efficiency during examinations. Its thoughtfully designed form minimizes operator fatigue while providing a relaxed and stress-free experience for patients, all without compromising clinical accuracy.
Designed for precision and performance, the system delivers fast, smooth, and virtually silent lens transitions. This allows practitioners to make fine prescription adjustments effortlessly at the touch of a button, ensuring a seamless workflow and an enhanced patient experience.

Advanced Chart System
The ETR-770 features a comprehensive digital chart system designed to support a wide range of visual acuity tests. It includes multiple optotypes such as Tumbling E, letters, numbers, and pediatric charts, as well as specialized tests like cross cylinder, astigmatism evaluation, red/green balance, Worth 4-dot, and fixation targets. With a total of 33 chart options available for both distance and near vision testing, practitioners have the flexibility to perform precise and customized examinations tailored to each patient’s needs.

User-Friendly Operation
The clean, pole-free symmetrical design allows examinations to be performed seamlessly from both the right and left sides of the patient. This enhances workflow flexibility and enables multiple ETR-770 units to be arranged efficiently in a variety of clinical layouts.
Designed to adapt to any examination preference, the ETR-770 supports both sitting and standing positions. Its ergonomic versatility ensures a comfortable experience for practitioners while maintaining consistent accuracy across all measurement styles.

Flexible Installation
Unlike traditional refraction lanes that require significant space, the ETR-770 offers exceptional installation flexibility. The system supports an adjustable optical distance ranging from 0.1 to 2 meters, which simulates a standard 5-meter testing distance. This allows it to be installed in environments where space is limited without compromising diagnostic accuracy. Whether in a compact retail setting or a mobile clinic, the ETR-770 adapts easily to different layouts and operational requirements.

Cloud Connectivity & Remote Refraction
The ETR-770 is designed to support modern, connected eye care environments through advanced cloud integration and built-in WiFi capabilities. By leveraging advanced architecture, multiple devices can be seamlessly connected into a unified network, enabling centralized management and real-time communication across locations.
This connectivity allows practitioners to remotely access and control the refraction system from virtually anywhere. Optometrists can perform examinations without being physically present at the optical shop, communicating with patients in real time through integrated audio and video features. This not only improves efficiency, but also enables a single specialist to support multiple locations simultaneously.

Flexible Operation Modes
The ETR-770 offers dual-operation flexibility. Practitioners can operate the system directly from the on-site control panel or remotely via dedicated software, ensuring adaptability to different workflows and practice models.

Connect Everything. Work Smarter
Two built-in RS-232 ports allow the ETR-770 to link directly with an autorefractometer and a lensometer, creating a faster, fully integrated diagnostic workflow.

The ETR-770 is an excellent solution for optical stores seeking to maximize space efficiency, ophthalmology clinics looking to modernize their diagnostic capabilities, and optometry practices aiming to improve workflow and patient throughput. It is also ideal for telemedicine providers and mobile eye care units that require portable, high-performance equipment. Its versatility allows it to meet the needs of both traditional and emerging models of eye care delivery.
