Subjective Refraction


Subjective Refraction

Automated Subjective Refraction

Provide your patients with a vision testing experience that exceeds their expectations

Combine these two ZEISS refraction instruments to give an exam room experience that delivers precise results your patient can trust. With the ZEISS subjective refraction unit, you can create a stress-free environment and save chair time at the same time.

As an eye care professional, your patients expect you to provide them with the best vision based on accurate refraction. However, this process demands a high level of trust and can lead to uncertainty in the prescription. Supported by advanced vision testing technology by ZEISS, you can transform the refraction process into a great experience, removing doubts and turning a stressful situation into a pleasant patient experience.

Start your subjective refraction by seamlessly transferring the prescription generated by the ZEISS i.Profilerplus® to the ZEISS VISUPHOR 500. Then use ZEISS i.Scription technology, provided by the ZEISS i.Profilerplus, to guide your patient to new lenses and better vision right in the exam room.

    Modern and precise ZEISS vision testing at its best in one unit

    This subjective refraction unit by ZEISS provides a comprehensive eye examination to the patient by combining the central exam elements, vision testing charts and phoropter, into one smart solution.

    ZEISS VISUSCREEN 500 with Polatest technology comes with a variety of vision tests to perform monocular and binocular testing with different test charts, as well as special tests for children. Demonstrate the effect of the lenses with ZEISS i.Scription® technology using the integrated LED. In addition to the infra-red remote control, the ZEISS VISUSCREEN 500 can be operated via an intuitive iPad app for a fast and easy way to switch between test charts.

    Personal workflows allow the compilation of different test chart sequences based on the individual preferences of various examiners. ZEISS VISUSCREEN 500 can be easily combined and upgraded with ZEISS VISUPHOR® 500, a digital phoropter, to streamline your examination workflow and create a modern, professional impression for your patient.

    The full integration into ZEISS i.Com mobile closes the loop among your devices by transmitting your patient’s measurements from the ZEISS VISULENS 500 or ZEISS i.Profilerplus / ZEISS VISUREF 100 directly to your subjective refraction unit, providing a quick and straightforward way to initiate your manifest refraction.
