Features:
1.Non-contact and non-invasive:The light power is safe for eyes; There is 35cm(14 inches)between the instrument and the eyes.
2.Child-friendly:Little cooperation is required, suitable for infants and those who have a language barrier.
3.Speedy Inspection:One Key operation to complete the automatic detection of two eyes:
4.Accurate Result:The advanced optical detection principle provides an accurate result: including myopia, hyperopia, astigmatism, axial and anisometropia.
5.Comprehensive detection modes:Infant mode is specially designed for infantsl Myopia model is customized for myopia people and even high myopia people (HAR-880 only); Adult mode is suitable for all adults.
6.Easy targeting:Luminant cross-shape facilitates the targeting for operator.
7.Ultrasonic distance measurement:Automatically monitor the distance with audiable and visual hint.
8.Printer: Thermal printer is connected by infrared.
