Pondering the contact lens...
Its an amazing little thing, I get away with avoiding headaches, and they even enhance my appearance, even if just slightly.
I've been searching for my size today, it seems the lenses I enjoy wearing are of a special depth and diameter, problem is it makes it more difficult to find within certain guidlines. I can't find those cute tinted Acuvue colours in my size. I often wonder if there is something wrong with me when I can't find so many things in my size, for example women's undergarnments for breast support and of course the contact lens. It seems maybe there is something to do with the cornia and the breast after all they are both sort of soft yet firm and very round! Some people would go farther and say they are both related to the moon, but I disagree because I see the eye as more of a "Pluto" thing.. related to the depths of the soul.
Its only fitting my size is difficult to find!
With a little accidental study, we find that the concept for the contact lens starts in 1508 with Leonardo da Vinci (naturally!) ( really wish people would stop attributing these "codes" and junk to him when the real genuine research he came up with was far more interesting, as well as his conclusion that being a vegan was a kinder way to live)
Da Vinci described a cup containing water which was placed over the eye so that the cornia itself would not refract light, thus reshaping the surface of the eye and correcting vision. With this in mind, he was probably the inspiration for lazer correction since this too makes the refractive surface of the cornia become corrected.
It seems that the first successful atempt at creating fitted lenses in the eye was by zeiss, a company known for their work with optical lenses, still being used in cameras today. They were known for having the clearest quality of lenses.
I just accidently gleened this information, (but not all the details) off of this sight

But I still hadn't found what I was looking for, a reason my iris size is harder to find.. the truth is, when I looked at an "average" chart from 2002, which was placing matterials lenses were being made of, with the size of the fitting, my numbers lay far outside of the ones within the square of the chart. It also made it very clear why I always had so much trouble with special lenses and why my lenses used to cost so much more... but you wouldn't think a diameter would of 14.2 would be "large" but then combined with the base curve of 8.6, then the mystery is dispelled, simply that manufacturers have a size which is average, as in a shoe size, and with:
"Baskurva: 8.5
Diameter: 14.2"
Acuvue, you lost a potential customer, its too shallow and thus too small, but closest I can find with them. Too small and the lens can cause damage to the cornia after a few short months!
So I guess I have to stick to boring lenses :( the ones with the boring colours (non at all) and try hard to look for those "biocolour" lenses I've been searching for, as they are the only ones in my size.
