This computer refractometer test sheet provides information: ① Continuous testing of the right eye is relatively stable; ② Continuous testing of the left eye 5 times, the detection deviation is too large (±1200 degrees); ③ Recommended reference values , right eye: -4.25-0.50×79; left eye: -3.00-0.25×150.

If [R, 350; L, 275] can be used to correct one eye to 1.0 and both eyes to 1.2, it should be considered that the correction power is reasonable.
