ML RP is a optical system that is mounted into a frame. The system makes the image smaller which means a wider field of view. A good analogue is to compare the ML RP with a peephole for doors.
The ML RP is an inverted Galilean system with a magnification of 0.5X.
The system is very easy to mount in a frame. It should be used as a bi system mounted above or under the patient's normal angle of vision.
A correction and a filter can be incorporated into the system.
The ML RP Monocle looks like a magnifier that you have in a strap around your neck. Instead of magnifying, ML RP Monocle minifies. This means a wider filed of view.
The standard power of the lens is -7, but ML RP Monocle is avalible also in powers -8 and -9.
