Air bubble under RGP lens
JennyDyer
I just got new RGP contacts about 3 weeks ago. They are fine when I first
put them in, but by about 10:00 or 11:00 in the morning an air bubble will
appear under my contact in the very center of the lens. It will go away on
its own after several blinks, but it usually returns unless I rewet the
lens. Both lenses have done this, but my right one is the worst.
Is this a fitting problem or something else? I've tried a couple different
wetting and soaking solutions, but it hasn't made any difference. Unless
there's no other option, I'd rather not ask my OD about this, because I've
already been pretty hard to fit. This is my third set of lenses, and I've
made nine trips to his office since May. If I don't get this problem
corrected, will it do any damage to my corneas--drying or anything? I'm
trying to decide if I can live with this for a year until it's time to get
new lenses again. The lenses are completely comfortable, and I don't have
any other problems with them. I'd appreciate some advice. Thanks.

Sounds like the lens curvature doesn't match that of your cornea very well.
Probably too steep, trapping corneal metabolic gasses .

One more trip wont hurt. Make sure you time the visit so the bubbles
are there when he/she looks.

You can live with it and it probably won't damage you, but I'd get it
fixed.
(kinda like shoes that are too big. An air space (bubble) behind your
heel might not hurt much, but why put up with it?)

One would assume your doc has determined that there is no health problem
associated with the condition and if your vision is good and you're happy,
I wouldn't loose any sleep over the bubble.
It is indeed a problem with the fit and should be able to be fixed, but
sometimes, especially if it is a transient phenomena, it's best to leave
it----the fix might make something else go off. Seems like you and the
doc have been around this before and he/she feels this is the best that
can be done. If it was me, I'd work pretty hard to eliminate the bubble.
If the bubble persists, it is possible that some damage can occur. You
might notice decreased vision WITH the lenses and markedly decreased
vision with your eyeglasses. There may also be discomfort following
removal of the lens. That being the case, do seek a remedy.

Again, if the doc has determined that there is no significant problem with
the corneal health and you are otherwise satisfied with vision and
comfort, don't worry so much.
