Optician India

By Óscar Pérez García

Many practices feel secure when progressive lens sales are strong and the bottom line looks healthy. Net profit growth is certainly encouraging, but it does not always reveal how sustainable the business will be over the next 10–15 years. For that, we need to understand not only how much we sell, but also who we are selling to.

Most opticians repeat the same cycle every year: close sales, compare results with the previous year, celebrate if net profit improves, and worry if it falls. However, one crucial strategic question is often missing: “Who is buying from me today, and who will buy from me tomorrow?”

To address this, we propose a simple but powerful indicator: the Optician’s Youth Ratio (RJO).

Defining the Optician’s Youth Ratio (RJO)

The RJO is designed to measure the relative weight of young patients within the total ophthalmic lens sales of an optical practice. It is simple to calculate and easy to monitor year after year, turning age structure into a clear numeric indicator.

Let:

[x] = number of lenses sold to customers up to 44 years of age.
[y] = number of lenses sold to customers aged 45 years and above.
[x + y = z], where [z] is the total number of ophthalmic lenses sold in one year.
To standardise the metric, we normalise the total volume to 100:
Set [z = 100], so [x + y = 100].
The Optician’s Youth Ratio (RJO) is then defined as:
RJO = [x / 100].

In other words, the RJ represents the percentage share of lenses sold to patients aged 44 or younger within your annual lens sales.

A Practical Example from Daily Practice

Consider a medium-to-large optical practice in 2025 with the following annual lens sales data:

[x = 1,319] lenses sold to customers up to age 44.
[y = 2,152] lenses sold to customers aged 45 and above.
Total [z = 3,475] ophthalmic lenses sold.
Normalising this to 100:
[x + y = 100].
The distribution becomes 38 (up to 44 years) and 62 (45+ years).

Therefore:

RJO = [x / 100 = 0.38].
Tracking this indicator over several years for the same practice yields the following RJO values from 2019 onwards:
0.34 – 0.38 – 0.36 – 0.39 – 0.37 – 0.36 – 0.38.

The conclusion is clear: despite natural fluctuations, the practice is not losing its young customer base. Its capacity to attract and retain younger patients remains stable over time.

Why Young Patients Matter More Than Today’s Profit

High progressive lens sales are profitable and often drive significant revenue for the practice. However, a deeper analysis shows that a 35?year?old patient can have a much higher lifetime value than a typical presbyopic patient.

A 35?year?old who uses prescription spectacles, sunglasses, sports eyewear and contact lenses, changes glasses every two years, and has children who also wear spectacles, represents a broad and recurring revenue stream. This profile reflects cross-selling potential, multi-pair sales, and family referrals.

The RJO captures something more subtle than immediate profit: the real renewal of your customer base. A low or declining RJO means that, although the practice is generating income today, it is not building the foundation of tomorrow’s clientele

Other sectors have already experienced similar situations. For years, many television networks reported strong audience numbers and high profitability, but their viewers were aging. When advertisers examined the average age of their audiences, the market value of those channels fell sharply.

In the same way, an optical practice with an excellent current balance sheet but an aging patient base may see its market value erode in the medium to long term.

RJO as a Strategic Indicator, Not Just a Business Metric

A declining RJO in a real-world optometry or optical practice is not merely a business problem; it is a strategic problem. It signals that the practice is not sufficiently attractive to younger generations, and that the brand may be losing relevance for future customers.

This has direct implications for succession and exit plans. If the owner intends to retire and sell the practice in 10 or 15 years, the buyer will not only look at current revenue or the value of equipment and furniture. They will evaluate:

The age profile of the active customer base.

The rate at which new, younger patients enter the practice.

The perceived strength and attractiveness of the brand for upcoming generations.

An aging, stagnant clientele reduces the perceived value of the business, whereas a vibrant brand with ongoing generational renewal significantly enhances it.

In other words, the true value of an optical practice is not limited to its present-day profit and loss statement; it also lies in the demographic health of its patient portfolio. RJO offers a simple, quantitative way to monitor that dimension.

Implementing RJO in Your Optical Practice

One of the strengths of the RJO is its ease of implementation. Most practices already record patient age and type of product purchased, so only a basic extraction and classification of annual lens sales by age group is required. By calculating the RJO every year and analysing its trend over time, the optician gains an early warning system regarding generational renewal.

Used consistently, this indicator can guide marketing and management decisions such as:

Investing in communication channels and messages that resonate with younger adults.

Reviewing the product mix (frames, lenses, contact lenses, sports eyewear) to ensure relevance for younger demographics.

Designing family-oriented programmes and loyalty strategies that connect parents and children to the practice.

RJO is offered as a practical tool for opticians and eye care practitioners who wish to go beyond traditional financial metrics and manage the real future value of their business. For those interested in deepening their approach to marketing and management, this concept is part of a forthcoming book project, in which professionals are invited to participate with feedback and experiences.
