Version 2.3:
Oh dear. Version 2.1 had more bugs in it than an entomologist's office. Sorry about that.
This version fixes the inability to even use the Effective Diameter tab.
For 2.2:
Fixed bugs on the Vertex Distance page which kept flipping around the vertex of Rx and specs values. Also fixed the precision value not being remembered.
Also the plus cyl form switch on the power entry screen was messing up the cyl power.
For 2.1:
Fixed bugs on lens thickness page which always showed "edge thickness" even for a minus lens, and only allowed 1 decimal point for the refractive index.
Also updated to work well with iOS 15.
If you want new features or calculations, don't hesitate to contact me!

Lens thickness calculation uses the approximate sag method to determine centre or edge thickness of lenses. Please note that this gives an indicative value only, and should not be taken as accurate.
The multifocal markup allows you to measure the heights of a multifocal once its dotted up.
