Automatic refractometer FKR-8900

Refraction is to check the concentration of light after entering the eyeball. It uses the state of emmetropia as the standard to measure the difference in vergence and dispersion between the examined eye and the emmetropia. Since many people will become attached to glasses almost in their lives, optometry is one of the most basic, most commonly used but important jobs for optometrists. Therefore, as far as the term optometry is concerned, in social life, regardless of Ophthalmologists, or ordinary people, are very familiar.

Product Advantages

1. It integrates optometry/corneal curvature measurement functions.

2. Leading optical technology, good measurement consistency, to ensure accurate and reliable measurement data.

3. The most advanced image processing technology makes the image clearer and the measurement speed faster.

4. The humanized auxiliary focus ring function makes the focus capture faster.
