Squinting - is a 'sunny day' squint = a 'blurry image' squint??

Reminder: Me = severe dry eyes, despite 4x punctal cautery; severe
ciliary spasm (etc., etc.)

To combat the effects of (glare, breeze, dust, etc.) on my dry eyes, I
squint an awful lot when the environment dictates: outdoors, in
heavily ventilated buildings (grocery store, Home Depot, etc.),
despite use of Panoptx sunglasses.  A movie in an air conditioned
theater, for example, is exceptionally tough on me.

Any idea whether /that/ sort of squinting induces accommodation in the
same way that squinting to clear a blurry image (presbyopes/hyperopes
trying to read without their glasses) does??

Here's why I ask: I'm awaiting a referral to Perry Rosenthal, in
Boston, to be fitted with his Scleral Prosthetic Lens.  It's used in
treating intractable dry eye cases (among other things).  I'm
theorizing that--if it helps reduce the time that I'm squinting--and
if all squinting induces accommodation--then the lens should help
ameliorate /both/ the dry eye pain /and/ the accommodative spasm
frequency/severity.

Thoughts?  Data?

TIA,

Neil

Not the same.  Squinting reduces blur by artificially constricting the
effective pupil ares ("stepping down the F-stop" in phogography jargon),
more the same way as looking through a pinhole does. However, you may
get other benefits that may help with the other problems, benefits that
are not easily quantifiable, so keep an open mind.  Good luck.

Neil,

Have you tried moisture chamber eyeglasses? They're similar to the Panoptx but
use plastic instead of foam, trapping moisture more effectively, and use regular
eyeglass frames. Info and pics here...

I haven't, but I have seen the site.

My supposition has been: to do markedly better than the Panoptx, you
basically have to go anaerobic (totally sealing out air, a la swim
goggle), increasing risk of corneal edema (or related problems),
especially since I almost always wear scl's (reducing accommodative
demand).  

Is that your experience, too, or can a plastic gasket walk that fine
line adequately?

Thanks, Robert.

You're welcome. I can only provide anecdotal evidence for moisture chamber
performance compared to Panoptx, although it seems reasonable to assume that
plastic will trap moisture better than foam, along with the potential for a
better seal because of the custom fitting. The custom fit also allows the use of
traditional eyeglass frames. Time consuming and a PITA to make but for those
with painful dry eyes (Sjogren's Syndrome) it seems to be the only way to go.  

I don't believe that hypoxia and the resulting edema would be an issue with
moisture chambers, more likely a concern if you are wearing CLs.

Regards,

Great book.  Compelling look at a young boy's entry into little league
baseball.

Should be required reading, if you ask me.
