Default Boston XO2 Optical Center

While reading about the design of contact lenses, I learned that there's a portion in the middle of the contact lens that's called the "optical center." Around the outside of this is the rest of the contact lens that forms a kind of "rim" to stabilize the optical center.
I then learned that the border between the optical center and the outer rim is visible under a microscope, but not to the naked eye.

Cool huh?

Okay, so instead of the "optical center" it's called the "optic zone" and what MopJockey called the "outer rim" is actually called the "peripheral curve"? Does Mopjockey get any points?

lol it is interesting isnt it? If it is a multifocal, apsheric, or toric fit....there could be secondary and third curves placed onto the lens front or back depending on the prescription ordered.

Boy, so much for contact lenses being just simple discs of plastic.

Well, if it weren't for all that "secondary and third curves placed onto the lens front or back" stuff you mentioned before, then I think it would be a lot easier to buy contact lenses, no?

Yes, that's true. I guess those RGPs are not very flexible and so the fit has to be just right.

That is pretty cool. I wonder if anyone has been curious about looking at their Boston lenses under a microscope?

yes final comfort after adaptation is primarily the fit of the lenses. They have to fit bang on.

"Bang on." That's an expression I don't hear very much. I like it. Sounds like something I'd hear on Top Gear. "The acceleration is quick, and the shifting is bang on."

That sounds like a Monty Python sketch. "How to Talk Like You're British." That's got to be more popular than "Being Hit on the Head Lessons."

Yeah, right?

"Stop hitting me."
"Stop hitting you?"
"Yes!"
"What did you come in her for then?"
"I wanted to complain."
"That's next door. It's Getting Hit in the Head Lessons in here."
"What a stupid concept."

So how long does this adaptation period typically last, assuming a "bang on" fit?

That doesn't sound so bad, luvbostonxo2's. Do you wear them for like, two hours the first day and then gradually increase the wear time?

Yes definately. Gradual buildup of wear to a full wearing period from the time u get up to bed time requires that you go through the adjustment period. The average is six weeks or so.

The beauty of ultra permeable materials is that once you are adapted to them you can wear them fulltime, partime or just hear and there. It was once thought that you had to wear them full time to maintain comfort,like the now defunct PMMA lenses. Even lower dk materials won't allow you to wear them partitme because the behaviour of the low dk materials behaves like old pmma lenses.

Anyone who is wearing older low dk materials, could def benefit a change to the newer hyper dk materials! Because of the ulra high o2 transmission, adaptation is much easier as well.

What is the typical gradual buildup schedule? How long do people generally wear their contacts lenses on Day 1? Day 2 and so on?

2hrs- 1st day then add an hour each day until fulltime wear is achieved! If there's sensitivity redo the wearing time from the previous day and then continue adding an hour each day!

That sound pretty simple. It seems like a really slow process. It would take someone almost two weeks to build up to twelve hours' wear--and that's without any "redoing." I wonder if this has given anyone second thoughts about switching to RGP lenses? Would previous soft lens experience help this acclamation process along?

I think motivation is important and fit is paramount, as once the lens goes on after abiut 30min there should be minimal sensation.

Fit is paramount in comfort. Lens sensation is mainky the eye lids.

What about the "soft lens experience" that Bondjamesbond" asked about?

Is it possible to get a good fit on the first try?

Yes most definately and that comes from long time exoperience in fitting rgp lenses. For ecp's there are manufacturer seminars, symposiums, and fitting guides but the best rgp fitters are ecp's that have been fitting them for a long time.

If I wanted to search WebMd or some other site for a good Eye Care Professional, how much experience is a "long time"?

Yup. 10 years is a long time to be fitting contact lenses. I would imagine that you get to see just about everything in that amount of time. I've heard that it's one thing to do something right when everything goes well, but to get it right when something unexpected happens, that's where the practice comes in. If you can still fit contact lenses even when you're having problems, then you're a real pro. Anybody with a week's training can fit an easy patient.

Oh dear. I've only been posting here for about four years. So I won't be really good at this until 2017?
