WebA MORE ACCURATE PHOROPTER…. Vision-R 800’s exclusive optical module controls powers at 0.01 D and delivers continuous and instantaneous changes of sphere, cylinder and axis, at the same time. Refraction is made more accurate and prescriptions can be made in 0.05 D steps. Patients can now get the full potential of their vision! WebJun 13, 2024 · Putting a +3.00 D trial lens in the schematic eye will result in a -3.00 D neutralization in the phoropter. The same goes for cylinder power, too! Know your working distance and stick to it! You can tie a string to the end of your retinoscope and quickly check the distance from the phoropter to your retinoscope before starting.
