Comprehensive Refractometer View Tester Manual Phoropter Ophthalmic Equipment
Model: LTO-VT-8
1. Equipped with comprehensive measuring functions, it provides SPH, CYL, AXIS and pupil distance optometry
2. Durable and easy to operate
3. Easily and intuitively read the sphere focal scale value
4. High eco-friendly materials
5. Design fitting the face curve and no stimulation
6. Easy to take and clean
7. Free switch between the cross-cylindrical lens and the rotary prism
8. When rotating risk is turning by sphere,it can make sphere power adjust 3.00D for big scope.
9. It is designed expediently and smartly for particular cross cylinder.Supporting supplementary lens could increase scope of measurement.
