We run an online glasses company currently doing around 80 orders a day.

Our biggest issue is estimating Seg height from the customer. Currently we have around 20% refund on progressive lenses.

Anyone have any recommendations how to better estimate seg height for each frames lens? I know companies like zeelool and zenni have seemed to figure out a way to estimate Seg Height.

I also noticed this company seems to have some sort of solution: https://www.eyeglasses.com/segment-height.html

We're open to any recommendations and have anyone has a solution we are willing to pay. Let me know
