In the United States, your optician is required to provide your prescription as part of your eye exam cost. It is illegal to withhold it for payment.
BUT, it is not a requirement that they provide the pupillary distance. Any eyeglasses purchase needs this data. By not providing it, the optician adds friction to your purchase anywhere except their own store.
But, pupillary distance is not particularly complicated to measure. It can be done with a piece of paper printed accurately. This model was created to streamline the process of ordering glasses for a household where 4 people use them. The model is not particularly unique in implementation - I did prioritize the tabs being usable by either hand. This helps with different handedness and when you want to take a selfie of the measurement.
One side also features reversed numbers for use in mirrors or selfies. Simply flip it over and read the numbers the correct way around in your mirror.
The free market is only an option when we are free to take our business elsewhere. Take back a small amount of choice.
Printing instructions:
- Layers - this is a thin model, so going lower will give you a crisper finish. 0.12mm is ideal.
- Perimeters - the text is hard to keep crisp and clear. Sticking to 1 perimeter and enabling “extra perimeters if needed” will keep the appearance clean.
- Infill - 20-30% is a good amount. The single perimeter means this should be higher than might be expected to give the model some structure.
- Top/Bottom - go for two layers for each. Again, a thin model, but this will provide some moderate resilience.
REMEMBER: Pupillary distance is the measurement of distance between the pupils. Each side of this model shows the distance from the center (i.e. the nose). You need both left and right values, then you add those together to give your PD value. If you have 30mm right and 30mm left, your PD is 60mm (30 + 30).
The model cannot do this for you as any assumption of symmetry would leave people with asymmetric eyes unable to use this tool.
