onstottj / refraction-converter

A small command-line utility (Java) to convert refractions with astigmatism from plus to minus notation, and vice versa

Refraction (with Astigmatism) Notation Converter

How to run it

1. Install Maven and add it to your PATH
2. In this project folder, run mvn package
3. Execute it with java -jar target/converting-refractions-sample-1.0.jar

Another option is to download converting-refractions-sample-1.0.jar into a folder and run it with java -jar converting-refractions-sample-1.0.jar.

Enter a plus-cylinder refraction like "+0.25 +1.25 x170" to convert it its negative-refraction, "+1.50 -1.25 x080".

Notes

This was developed using TDD.

The refraction, converter, and input validator classes are ready to be re-used. They could be made into their own Maven library by separating them out into their own artifact.
