Semi-automatic computer refractor WZ 988KR
Description
Technical Specifications
Core Nature
- A computerized optometry device is an electronic objective instrument integrating refractive examination and computer technology.
Measurement Capability
- It quickly & accurately measures eye refractive power, providing key data for ophthalmic diagnosis and spectacle fitting.
Objectivity & Standards
- Without subjective input from clinicians/examinees, it evaluates refractive parameters objectively per preset criteria.
Application Scope
- Used in ophthalmic hospitals, optometry centers, optical shops, it supports vision screening, preliminary diagnosis of refractive errors (myopia, hyperopia, astigmatism), and determines accurate lens power for fitting.
