Team sizes at optometry practices in Missouri
39.3% of Missouri's optometry practices with employees had fewer than five people in March 2023, compared with 47.9% nationally. 81.7% had fewer than ten. At that size the phone is shared, so routing (who rings, when, and what happens after hours) matters more than the number of desk phones.

|---|---|---|---|
| 1–4 employees | 168 | 39.3% | 47.9% |
| 5–9 employees | 181 | 42.4% | 32.2% |
| 10–19 employees | 61 | 14.3% | 15.5% |
| 20–49 employees | 14 | 3.3% | 4.0% |
| 50 or more employees | 3 | 0.7% | 0.4% |

What optometry practices in Missouri use the phone for
Eye-care offices combine exam scheduling with eyewear and contact-lens orders, so callers want both appointments and order status. Calls about broken glasses or eye irritation also need to reach someone quickly.
Calls an optometry practice in Missouri might handle in a typical week include:
- Someone calls about sudden eye irritation and asks whether to come in.
- A patient calls to reorder contact lenses.
- A patient calls to check whether new glasses are ready for pickup.
Texting patients
Optometry offices text patients when an eyewear or contact lens order is ready for pickup, along with appointment reminders.
Texting from a local number in Missouri requires carrier registration (10DLC), a one-time $49 fee on Callata.
