Sunday, March 12, 2017 Revenue per Manufacturer

One of the many ways that I slice and dice the data that I pull from LentillasSi is sales per manufacturer. I track things like the gross margin for each, the number of units, the reorder frequency, etc. to try to get a better understanding of our sales.

Most of the data is private for competitive reasons, but some can be shared, and I will do so when possible. One shareable bit is the percentage of revenue per manufacturer. From this data, I've only included the big 4 (in revenue order): CooperVision, Alcon, Bausch & Lomb, and Johnson & Johnson.

CooperVision has been our best selling manufacturer forever. Biofinity and Proclear make up the bulk of the sales, but their newer dailies (especially Biomedics 1 Day Extra) are coming on strong. Although they made up 40% of our revenue, that's actually down from last year, when they made up 41%.
Alcon (formerly Ciba Vision) is the manufacturer that grew most notably from last year, from 22 to 24% of our revenue. Their sales are more spread out, with Air Optix Aqua leading the pack, Dailies Total1 as our most popular daily lens, and Air Optix Colors being our most popular monthly lens.

Bausch & Lomb
Bausch & Lomb leads with their SofLens line, but we also sell quite a few of their liquids. Both Renu and Biotrue are big sellers, and also highly regarded by our optician. SofLens 59 is one of highest selling products.
Johnson & Johnson
Finally, Johnson & Johnson makes one of our perennial bestsellers, Acuvue Oasys. Their daily products, especially TruEye and Moist, are not selling as well in Spain as they sell in other countries, although there is a lot of excitement about the new Oasys Daily Lenses. Johnson & Johnson has also discontinued the Acuvue Advance line, and we're now selling off our remaining stock.

LentillasSi - #1 in Customer Satisfaction is rated #1 in Customer Satisfaction by our users!

Our customers scored 9.8 / 10 in customer satisfaction. We already knew Susana was the best customer service rep on the planet, but now eKomi has certified the fact.

I've checked the rankings of all the websites that sell contact lenses in Spain, and quite a few more that sell in other countries, and I didn't find anyone ranked higher than us. eKomi only awards gold for sites with ratings of 9.6 / 10 or higher, and I found NO ONE else that has a gold ranking.

What Makes LentillasSi the Best

Besides Susana charming the customers, has a lot to offer: standard next business day tracked shipping, more than 2/3rds of ordered goods in stock (and that percentage is growing quickly), cheapest prices, lowest shipping costs (free in most cases), Confianza Online compliance, multi-layered web site security (including end to end encryption), and a fast, world class, "mobile first" website all contribute to the ranking.

We have systems built to check every step of the user process. If we can't find the city associated with your postal code, we get informed. If a client has problems creating an account or adding a product to the basket, we get informed. We are constantly monitoring and improving every little detail of the customer experience.

What the Future Holds

What we find encouraging is that there is still so much to do! Our sales are growing by leaps and bounds, but we are working hard every day to improve the experience. Improvements in payments, site speed, site usability, product selection and packaging are all in the works. We can't wait to find more ways to keep our customers happy!

Recently, while preparing the databases for use on a web shop, I generated a curious list....

Alphafilcon A, Balafilcon A, Comfilcon A, Delefilcon A, Enfilcon A, Etafilcon A, Galyfilcon A, Hilafilcon B, Hioxifilicon A, Lidofilcon A, Lotrafilcon A, Lotrafilcon B, Methafilcon A, Narafilcon A, Nelfilcon A, Ocufilcon B, Ocufilcon D, Omafilcon A, Phemfilcon A, Senofilcon A, and Stenfilcon A.

For the optometrists among you, you will recognize that these are contact lens material names. I found the fact that everything that ended in filcon (Phil Collins? ;->) had to be more than an accident, and I was right: they follow very specific rules set up by the United States Adopted Names Council.

From my experience with tracking what web users are searching for, there was only one material that was really on my radar: Comfilcon (used in CooperVision products). Checking Google Trends, it's clear why... it's basically the only material that non-opticians know about. What is also curious is that the materials searched for by name are ALL from CooperVision - none of the other manufacturer's materials are known by the general public.

The one exception to the naming convention is Polymacon, used in some SofLens products. So far, I have not found the reason that this material does not end in "filcon". I'll update this post when I find out.

Lentillas (Contact Lenses) in Spain

Susana from is telling me that they sell lentillas (Contact Lenses) there. Tell her I sent you and you will get... well, just the normal excellent service and lentillas baratas (cheap lenses) that you get every day and Lensbase.

They are growing by leaps and bounds (as is the Spanish online contact lens business in general), and you can read on the testimonials page exactly how happy the customers are.


Update: Susana and I no longer work for lensbase... we have set up our own webshop at We sell lentillas (contact lenses) even cheaper now, and the lenses are shipped from Spain, meaning you get them faster.

Money Saving Expert

I just reread the contact lens article on Money Saving Expert. It has lots of interesting info, mostly about saving money, but also sections like "Are daily lenses secretly the same as monthlies?". Check it out.

The Eye of the Beholder

Competence, like truth, beauty and contact lenses, is in the eye of the beholder.
