Default Same Material?

This is a very interesting statement. I went to lens.com to check on this. You claim that daily disposable contact lenses made by Bausch & Lomb "use the same lens material" as their monthly disposable contacts.

I found out that the only daily contact lenses Bausch & Lomb makes are SofLens Daily Disposable contact lenses. They are made of 41% polymer (hilafilcon B) and 59% water.

Optima 38 contacts, monthly contacts manufactured by Bausch & Lomb, are composed of 62% polymacon and 38% water.

The other monthly B & L contact lens is PureVision, which is 64% balafilcon A and 36% water.

I'm no materials expert, but those all sound like different materials to me. How can you say that all B & L dailies and monthlies use the same material?
