I've been wearing a minus 14.5 in my left eye only. I wear Focus
Monthly's. Lately, they've become difficult to wear. I found an
older -14.0 Precision UV, and that feels great. So, I'm thinking of
asking my doctor to change my prescription. I'd like to find out
first which (non-custom) lenses come in that strength, so I could look
up prices and availabilty first, and then ask my doctor which of the
ones I've found she prefers for me.

Can anyone tell me which other lenses come in -14.5. Thanks.

Hi...

Why are these long-use lenses not available (or not prescribed)
anymore? Is it because of some property inherent to the lenses
themselves or because people wore them too long, didn't clean them
properly, etc.?

I'm mostly curious, because I used to have great success with these,
many years ago, and have noticed that no one among my acquaintances
wears them now.

Good to know.

I have problems swallowing that. Glass is pretty darn cheap. I buy
lots of sterile things in glass. My theory is that the lenses are
really cheap, and it's other costs that they need to recover. I suspect
that they are looking for a certain amount of money per year per
patient. Those old vial lenses used to run me US$100. A year's worth
of monthly foil packs wasn't much more.

ObReallyStrange: Before my first cataract surgery, somebody from my
church (a retired nurse) gave me a pamphlet that she found in her attic.
It said that there was a new option rather than those terrible phakic
glasses. You could get contacts! They didn't have the disadvantages.
The doctor would insert them into your eyes, and you would come in once
a year, where the doctor would remove the contacts, inspect them and
clean them. The doctor would then reinsert them until the next year.
