Characteristics
1.
It is possible to carry out both refractive power measurement as well as pupil information
with one machine.
2.
It is possible to measure the refractive power ranging from –8.0 D to +8.0 D.
3.
When measuring refractive power, it is possible to measure up to a minimum pupil diameter
Ø4.0 mm.
4.
It is hand held machine that can measure both eyes simultaneously in a short time at a
distance of about one meter.
5.
It can measure at the distance from the subject and align the measurement distance by
ultrasonic.
6.
It provides visual and audible sound for the child to focus on the measurement.
7.
This machine provides a fast data for easy evaluation of the most pediatric subjects of
limited compliance.
8.
It uses infrared light for eye measurement. This infrared light is invisible to the human eye
and nonhazardous.
9.
Because this machine uses infrared light to preform measurements, to accurate
measurements it is important to avoid interfering infrared ambient light in the examination room.
It is better to darken the examination room.
