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.
