Due to the degree of astigmatism I have, there are no soft contact lenses I can
use.  After 30 years with glasses, I have gotten hard lenses -- which are
VERY different than those I tried (and gave up on) 25 years ago.

These are the gas permeables, and new ones, at that.  These are even more gas
permeable than the soft lenses approved for extended wear, and the manufacturer
has already applied to the FDA to have them approved as extended wear also.

My eye-care professional (an optometrist) is quite "thrilled" with the fit, 
etc., exclaiming how this type of lens is "just made for" my eyes.  I have had
remarkably little trouble getting accustomed to them.

He is, however, also quite conservative.  He recommends that, until the FDA
agrees with the manufacturer, the lenses be worn for no longer than 13 hours a 
day, to give the cornea the other 3 hours at normal oxygen levels.

Is there anyone else out there with the background/experience to either agree
or disagree with that advice?  Keeping up with both lenses and glasses is more
hassle than either separately!
