iOS 18 breaks this app
Just updated to iOS 18. The cross cylinder calculation no longer works. You cannot enter the axis number correctly for both current Rx and the cross cylinder amount.
Very useful tool
Quick and easy to use at work (I'm a student dispensing optician). Also wanted to suggest something to the developer and got a really prompt and honest reply.
Great app but!!!!!
Great general ophthalmic optical app. However I wish you were able to plug in any index of refraction for calculations. World these days revolves around more than just standard 1.53 shop index.
Great optical app!
Great app - a must have for any dispenser or technician.
