Simulation eye practice

1. Retina pattern has accurate colour rendition with the physical dimension matching focal length ratio.
2. Ametropia (-5.00D to +4.00D) ,You can put any power on it to train,inculding the cylinder lens.
3. 3 levels of difficulty with change in the pupil size (3, 5, 7mm) ,Switchable by simulation of small, general and mydriatic pupil.
4. 3 layers of arc walls for refraction lenses or setting of different degrees of astigmatism and axial cylinder.
5. Degree of astigmatism axial angle disk is 0~180° .
6. Flexible stand with height adjustment.
7. Material: plastic and metal Size: 130x80x80mm
