Eye Pro 2013:
Cartesian/Polar Converter
This program converts from Polar (e.g. 1.35 D x124 Degrees) to Cartesian notation (e.g. X= -0.50; Y= -1.25) and vice versa.
FEATURES:
Cartesian (X;Y) to Polar (Cylinder/Axis) notation Converter:
•Easily convert each Refraction from the classical Polar (e.g. +3.25 x 30 Degrees) to Cartesian notation (e.g. X = 1.63; Y = 2.81) in order to perform standard statistics such as Average and SD on a group of eyes. The final result can then be converted back to traditional Polar notation for descriptive purposes.
WHEN TO USE:
•Polar to Cartesian conversion:
Before calculating Mean and SD, each individual value must be converted from Polar to Cartesian notation.
• Cartesian to Polar conversion:
This is to be used at the end, to convert the calculated Mean and SD back to Polar notation, which is more useful for descriptive purposes.
