HIGH QUALITY: Adopting high quality material, which is durable and also environmental friendly
RETINOSCOPE PRACTICE: Coordinate with the retinoscope practice, simulate real eye. There is scale on the lens-barrel which represents different ametropia
DIFFERENT PUPIL: 3 levels of difficulty with change in the pupil size, switchable by simulation of small, general and mydriatic pupil.
ARC WALL: 3 layers of arc walls for refraction lenses or setting of different degrees of astigmatism and axial cylinder
EASY TO USE: Simulated design is more convenient to practice optometry, easy and flexible to operate. Degree of astigmatism axial angle disk: 0~180 degree
