Prescription Management for Optical Shops: Never Lose a Customer's Eye Power Again

Published 26 October 2026 · 4 min read · By Anjali Yadav

A regular customer walks in and says, "Same power as last time, please." You open the register, search through pages from last year, and cannot find it. The customer has to get their eyes checked again, or worse, goes to another shop.

A customer's prescription, the "eye number" or "chashma number" most customers ask about, is the most valuable record in an optical shop. Saving it properly is the easiest way to win repeat business. Here is how Opticdigit helps.

What a complete prescription record includes

For each eye (right and left):

• SPH (sphere)
• CYL (cylinder)
• AXIS
• ADD (for reading or progressive lenses)
• PD (pupillary distance)

Along with:

• date of eye test and who tested,
• lens type, material and coating chosen (for example ARC, HC, Blue Cut),
• frame purchased,
• notes for the next visit,
• where relevant, clinical notes such as BP, sugar or IOL power after cataract surgery.

Problems with paper and generic apps

• Registers get lost or damaged. Water, torn pages or a full book that went to the storeroom.
• Hard to search. Finding one customer from two years ago takes time.
• Typed into item names. General billing apps have no prescription fields, so staff type "-2.25/-0.75x90" into the product name. It cannot be searched later.
• No link to billing. The power is in one place, the bill in another.
• Lost lens orders. Which job went to which lab, and is it back yet? On paper, nobody knows until the customer asks.

How Opticdigit manages prescriptions

• Eye number on the bill. SPH, CYL, AXIS, ADD and PD for both eyes are entered on the invoice itself and saved to the customer's history.
• Linked to the customer and the bill. Search by name or mobile number and see their full history: past powers, lenses and frames.
• Power change at a glance. Compare this year's power with last year's.
• Clinical records alongside the power. On Premium and above, record BP, sugar and IOL power with the eye prescription.
• Lens pre-orders and lab tracking. On Premium and above, book a lens order against the prescription and track it from lab to fitter to delivery.
• Reminders for the next check-up. Opticdigit sends an automatic eye check-up reminder by SMS when it is due.
• Safe in the cloud. Records are backed up online, not stuck on one computer.
• Works everywhere. Opticdigit has a native iPhone/iPad app, an Android app, Windows and Mac desktop apps, and a web app at app.opticdigit.com, with offline billing on every plan.

Why it brings more business

1. Faster service. Repeat customers are served in minutes.
2. Trust. Customers feel looked after when you remember their power.
3. Upselling made natural. "Last time you took ARC lenses; would you like Blue Cut this time for screen use?"
4. Repeat visits. Automatic yearly reminders bring customers back to you.

Moving your old register into Opticdigit

You do not need to enter every old record on day one. Start with:

1. Customers who come regularly.
2. Customers from the last 12 to 24 months.
3. Every new customer from today.

Within a few months, most of your active customers will be in Opticdigit.
