Handy and convenient app that transposes any eyeglass prescription from minus cylinder form to plus cylinder form, or from plus cylinder to minus cylinder. Helpful for optometrists, ophthalmologists, opticians and their staff. Avoid errors in prescription transmission, or use to double check transposition accuracy.

Axis 160

Axis 160 is listed as 169 needs to be fixed, scrolling takes a long time, wish we could just type in the RX, and can only look up one eye at a time would be nice if we were able to do 2 eyes at once. Definitely outdated and needs an update. Looks like they just uploaded it and forgot about it. All in all it does get the job done. Hopefully someone will see this an put out an updated version!
