Eyeyeyeyeye,
Axis error
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.

benichols,
Axis incorrect
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.
