What is an Autorefractometer and What Does it Do?
An AUTOREFRACTOMETER is a sophisticated piece of ophthalmic equipment used to measure the refractive power of the eye. In simpler terms, it helps determine the correct prescription for glasses or contact lenses.
How Does it Work?
This device uses a combination of infrared light and advanced optics to:
- Measure corneal curvature: The keratometer component measures the curvature of the cornea, the clear front window of the eye.
- Determine refractive errors: The refractometer component measures the overall refractive power of the eye, which can reveal the presence of nearsightedness (myopia), farsightedness (hypermetropia), or astigmatism.
Why is it Used?
- Objective measurements: Unlike subjective refraction tests (where the patient indicates which lens provides the clearest vision), auto-kero-refractometers provide objective measurements, reducing the potential for human error.
- Efficiency: The testing process is quick and non-invasive, making it a valuable tool for routine eye exams.
- Starting point: The results from an auto-kero-refractometer give the eye care professional a starting point for refining the prescription during a more detailed eye exam.
In summary:
An AUTOREFRACTOR is a valuable tool in modern optometry. It provides accurate, objective measurements of the eye’s refractive power, which is essential for prescribing the correct corrective lenses.
I wanted to know if all the calibration tools as well as accessories were available for each piece of equipment
This list is purely informative and in no way reflects reality. Please check the presence of the accessories in the photos below. No claim will be accepted. For more information you can consult the website
Do the photos correspond to the reference above or are they generic?
The photographs illustrating the products are contractual pictures. Photos are taken for each machine: each picture and each video are REAL ones.
Are your machines perfectly functional? And calibrated ready to cut?
The best machines and only “one first owner” models before, are choosen for being renovated process. Then, they are fully refurbished by our qualified technicians, and calibrated here in Montluçon, middle France. The products sold by SARL Digital Screen System are Second Hand market, so we encourage our customers to make an educated decision, take responsibility, and to remember that it’s still pre-owned ones, aesthetically and mechanically.
