The 'mirror method' is great for troubleshooting PALs, especially when the client has some kind of vergence issue, cyclo-dextro phoria, ect...
Here are the steps:
1. put the PAL markings on the lens.
2. place the mirror (approx. 8 inches square) in the middle of the dispensing table, flat
3. place a dot in the middle of the mirror.
4. have client look at the dot, with their eyewear/demo lenses on
5. carefully mark the demo lens on the patient, while looking in the mirror...this gives you the exact location of where they converge to read, a more subjective method....I would recommend practicing on co-workers first, it is tricky marking the lenses, kind of like a dentist, working upside down and backwards in a mirror.
It could be used to fit PALs off the mono subjective near PD, but that is a bit radical.
