I wore Fluroperm 151 RGP lenses from 1995 until last year when an
optometrist recommended that I switch to O2Optix lenses.  He said that
I would see better with an aspheric design lens.  Although I had less
of a problem with dust while wearing the larger soft lens, I think my
vision was clearer with the RGP lens.  For me, I'd rather put up with
some minor occasional discomfort in order to see better.  (Plus the
RGPs are more economical and I can sleep with them in.)

Are there any new RGP materials that allow more oxygen to get to the
cornea than the Fluoroperm 151s?  Are there any other reasons to
switch from Fluoroperm 151 to a different RGP material?

Just wondering. Don't you notice any scratches in your lens? I
get scratches in just 6 months. I wonder if some lens material
is more resistant to scratches. Is yours extended wear?

Noke,
I wear my soft lenses until they get uncomfortable (burning sensation
or feel loose).  This varies from 3 - 5 weeks and I don't know why
it's not more consistent.  I try not to sleep in them except for the
occasional short nap.

I haven't noticed that the soft lenses get scratched but then I make
sure my fingers are very clean when I take them out at night and I
usually soak without rubbing.  On the other hand, I wore my RGPs
continuously for a month and rubbed them to clean.  They DID get small
scratches so I had them polished every other year or so.

Didn't you read the advice of Mike Tyler. He said any scratched lens
have holes which can harbor stuck up mucus, debris, bio-junk,
bacteria, fungi, polishing material and/or ground up lens harming
the eye.

Well, I said most of that, but I didn't say "holes", I said "furrows."

But the furrows are microscopic, and they do get cleaner when you wash them.
Don't forget that gas perms the best safety record of any. Scratches and
defects are so uncomfortable it's hard to keep wearing them and people
don't.

Yes, stuff accumulates in the scratches, but it accumulates on the surface
too. Good cleaners make them safer by removing a lot of the gunk that
collects in the scratches and on on the surface.

Products like Lobob and  Boston GP Cleaner usually work better than
"multipurpose solutions."

sign of scratches. How could you use it for many years? Maybe
one must replace it yearly.

I recommend 12-18 month replacement on most gas perms.

I'm surprised that you say that one reason you want to keep with your old
RGPs, instead of O2Optix, is that you can sleep in the RGPs, and not in the
soft lenses. Actually, I would think that the O2O (I think now changed name
to AirOptix, being made of a highly breathable silicon hydrogel material,
sure would be better to sleep in than your old RGPs. Did your eye doc tell
you that it's OK to sleep in your 1995 RGPs, but not OK to sleep in the
O2Os??

Studies uniformly show that RGP lenses are associated with a lower
risk of eye infection during overnight wear than soft lenses, safer
even than silicone-hydrogel lenses.

I didn't know that. But did you see the original post, that I was responding
to? The guy is talking about RGPs that he has had since 1995! Old, perhaps
scratched, but beside that, even if at that time those lenses were rated for
EW, 13 years ago, there have been a lot of advances in contact lens material
since then, even with RGPs. So, would you say that his RGPs from 1995 might
be safer to sleep in, than a new pair of O2Optix?

That's why I recommended, if he chooses to sleep in RGPs, to ask his doc
about Menicon Z, I think the most permeable RGP lens available today. (I
think, if I remember correctly, meeting or surpassing N&Ds in dk/t.)

Still, I would think it might feel strange, to wear RGPs all night, every
night.
