Ezer Refraction System ETR-770
The Ezer ERT-700 is an advanced compact refraction system engineered to deliver a complete and efficient eye exam within an ultra-small footprint. Designed to meet the needs of modern optical environments, this system integrates essential diagnostic tools into a single streamlined unit, allowing practitioners to perform both subjective and objective refraction without the need for a traditional lane. Its innovative design makes it the perfect solution for clinics and optical stores looking to maximize productivity while minimizing space requirements. Additionally, the ERT-700 is widely used in telemedicine applications, enabling remote refraction capabilities where the examination unit can be located in one site while the specialist performs and controls the refraction process from a different location, such as their home or a central office. This flexibility opens new opportunities for expanding access to eye care services without geographical limitations.
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.

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.
Tele-Refraction Ready
The ETR-770 is designed with the future of eye care in mind, offering full support for tele-refraction capabilities. Through its integrated software, practitioners can perform remote exams using secure audio and video communication tools. The system includes data storage functionality and supports cloud-based infrastructure, allowing access to patient information across multiple locations. With servers distributed globally, it ensures stable and reliable performance regardless of geographic location, making it an ideal solution for telemedicine and multi-site operations.
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 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.
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.
User-Friendly Operation
Ease of use is a core component of the ETR-770 design. The system features an intuitive control interface that can be operated either directly from the control panel or through dedicated PC software. This flexibility allows practitioners to choose the workflow that best suits their practice. The interface is designed to reduce the learning curve, enabling staff to quickly become proficient while maintaining a smooth and efficient patient experience. Every interaction is optimized to simplify the refraction process from start to finish.
Connectivity & Integration
The ETR-770 is built to integrate seamlessly into modern digital practices. It includes multiple connectivity options such as USB, LAN, and RS232, along with wireless capabilities through Wi-Fi and Bluetooth. These features allow the system to communicate with other diagnostic devices and practice management systems, facilitating data sharing and improving overall clinic efficiency. This level of connectivity ensures that the ETR-770 can easily become part of a fully digital workflow.
High-Quality Illumination & Display
To ensure accurate diagnostics, the ETR-770 incorporates a high-resolution display system with LED illumination. 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.
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.
