There are two steps. First, plot the addresses of the stores that carry your product (https://www.mapcustomizer.com/)

Second, find optometrists near there (Yelp, Google, LinkedIn Advanced Search)

In all honesty, it probably took you longer to write the question than it would to find what you're looking for. :)

I'm happy to help more, book a call and we can get your rocking.

All the best,

I'd start by mapping out all the options and seeing what they cost you in time and money (eg: are you techical enough to code this up in your sleep, or is it easier for you to pay someone).
Optons:
1) like Shaun said. map it using https://www.mapcustomizer.com/ or http://mapjam.com/
2) getting a quote on https://www.upwork.com/ for a human to do it for one city first to see the ROI.
3) plug in a street address of a store into yelp as 'near' field and type in opthamologist.

After testing each one for one city, you can decide if you want to automate it or just scale the option up.

Feel free to schedule a call with me.

Hi,

I am currently actively working on a similar project. We perform actually marketing for medical practices throughout the United States. And interesting enough, I partnered with a company that markets pharmacies near the physician practices.

We are using a combination of WebMD along withhttp://factfinder.census.gov/faces/nav/jsf/pages/index.xhtml

Essentially, we break the information down according to the household income and other demographic information for our target population. We then contact the medical practices and pharmacies within the area where we know we can sell the products and services.

I hope this helps.
Best of luck,
