Electric Manual Phoropter, For Eye Testing, Color : Grey

The major components of the phoropter are the battery of spherical and cylindrical lenses, auxiliary devices such as Maddox rods, filtered lenses, prisms, and the JCC (Jackson Cross-Cylinder) used for astigmatism measurement. The prismaticlenses are used to analyze binocular vision and treat orthoptic problems.

From the measurements taken, the specialist will write an eyeglass prescription that contains at least 3 numerical specifications for each eye: sphere, cylinder, and axis, as well as pupillary distance (distance between eyes), and, rarely, prism for one or both eyes.
