The Essilor Vision-R 700 (V01) is an automated phoropter designed for performing refraction tests to determine optical correction or compensation, providing examinees with optimal vision. It is classified as a Class I, Type B medical instrument, marked with CE and compliant with FCC standards. Its estimated minimum lifetime is 7 years from the first marking in 2020.
Function Description:
The Vision-R 700 facilitates subjective refraction by inserting optical corrections, diopter compensations, and/or filters in front of the patient's eyes. It can perform measurements under monocular or binocular vision conditions, allowing for a comprehensive binocular vision examination. The instrument enables continuous variations of optical characteristics such as sphere, cylinder, axis, and prism. Its "automatic" nature means it integrates control of test projection systems from the same control panel.

Usage Features:
- Patient Data Input: Allows for objective refraction data input from lensmeters, auto-refractometers, aberrometers, or manual entry. Data can be imported from Essibox.com.
- Instrument Configuration: Users can set instrument data to zero, switch between manual and automatic modes, and import/export data.
- Patient Setup: Adjustments include horizontality of the refraction head, inter-pupillary distances (monocular or binocular), and forehead rest position (which affects vertex distance).
- Far/Near Vision Modes: Easily switch between far-vision and near-vision modes, which automatically adjust inter-pupillary distances, convergence, and LED lighting.
- Test Selection: Offers various test formats, including standard tests (far-vision, binocular-vision, near-vision) and "Smart tests" which use an algorithm for semi-automatic refraction. Users can select from a list of available tests, pre-selected favorite tests, or standard/personalized test programs.
- Optical Module Control: Allows changing the checked eye (right, left, or binocular) and modifying controlled settings (Sphere, Cylinder, Axis, ADD, Horizontal Prism, Vertical Prism). Power and incrementation steps can be adjusted.
- Value Locking Function: Useful for locking in specific values during examination.
- Masks and Filters: Apply black masks or spherical power masks to eyes. Filters can be personalized for monocular or binocular vision.
- Occlusion Type: Customize the type of occlusion applied to the unchecked eye.
- Patient Data Management: Add patient folders and manage patient information.
- Contextual Assistance: Provides on-screen help and phraseology for tests and console actions.
- Refraction Comparison (Bluetouch): Compares new refraction data with previous saved data (e.g., from lensmeter) and displays differences. Includes an "Alert function" for significant dioptric changes.
