Inventory analysis after 2025 campaign

This is a very rough interpretation of the results. Raw graphs are also shown here

This considers all dispensed glasses since the 2023 campaign and also unsuccessful searches made in (parts of) the 2024 campaign and all of the 2025 campaign.

The analysis for singlefocal is much worse than for multifocal since we have much more dispensed multifocals and therefore more data.

Check the grafana dashboard for the percentage of multi- vs. singlefocal per location.

sa single

we need

much more of zero-ish axis (from 160 to 0 to 20) with any sphere
also few more where at least one eye sphere is 0 specifically (and any other params)

we have

enough with axis not zero-ish (so 50 to 120) (and at least one cylinder > 0).

sm single

we need

more with a zero-ish axis, specifically:
- a lot more with a sphere of -1.5 to +1.5,
- some with any negative sphere and 0 to -0.5 cylinder
- also few with sphere of 0 (in at least one eye)
MAYBE? tiny amount more of glasses with high cylinders (-1 to -4) and 160 to 0 to 20 axis

we have

more than enough of axis around 90-ish (i.e. not close to 0 axis)

sa multi

we need

more with with any positive spheres and 0-ish axis / zero cylinder.
- rather with higher add (i.e. bigger than 2.5) than lower (less than 2), but also some of the latter

we have

more than enough of 90ish axis (like 70-110) (and therefore non null cylinders)
- especially for spheres higher than +1.25 much more than enough

sm multi

we need

muuuuch more with close to 0 axis and 0 to -0.75 cylinder, any positive spheres
some more of glasses with a smaller add value, i.e. -1 to -1.75 (and an axis that is roughly 0-ish) and any sphere

we have
