Past version This app has a drum system and is easy to use I have found some glitches Firstly the axis drums have an erroneous axis of 169 which should be 160 Secondly a negative axis appears This is not a big problem in that by subtracting that number from 180 gives the correct axis For example if lens worn is 2 50 1 75x167 and the Over Refraction is Plano 0 25x30 the result is 2 50 1 75x 9 9 is equivalent to x171 Update Axis problem is fixed Recommend increasing range of spheres to 20D Or having an optional window to type in the needed power Typing in an axis may save time spinning the drum                 Axis error Eyeyeyeyeye
I would gladly change my rating if this bug is fixed but I can t find anywhere to contact the developer It calculates axis wrong If you enter 2 00 1 75x175 for glasses and over refract 0 00 0 50x90 the result it gives is 1 51 1 26x83 it won t round this result either which is incorrect I cannot currently recommend purchasing this app until the error is corrected     Axis incorrect benichols
