Re: [Paddlewise] GPS Mount for Kayaks -- "Old Eyes" Problem

I have presbyopia (old eyes; need for bifocals) and I also hate to 
paddle in prescription glasses!  Contact lenses seemed like they would 
be a good solution, since they can be 
obtained with bifocal or progressive corrections.   That was not to be, 
however, because I also have a slight astigmatism, worse in one eye than 
the other. The solution, after some trial and error, was a "monovision" 
configuration. The following two sentences are taken from a website that 
explains the concept: "With monovision, you wear one contact lens with 
one power to correct distance vision and the other contact lens with one 
power to correct near vision. The distance vision lens is usually worn 
in your dominant eye.  While monovision may appear to be an unusual 
choice, most people actually accommodate well to it, and eventually 
don't even notice that each eye is responsible for a different part of 
their vision".  That's generally the case with me.  Although my acuity 
with the lenses isn't as good as it is with my glasses, it's  certainly 
good enough for paddling (I can see distances well enough -- with some 
loss of acuity, though -- and can read a chart or use my GPS without 
having to deal with glasses). While I indended, originally, to wear the 
lenses only for paddling, I now wear them most days. 

While we're on the subject of GPS usage:  my GPS -- a Garmin GSMap76 -- 
sporadically loses contact with the satellites when I lay it flat on the 
deck.  I've had better performance after I attached it to a minicel 
wedge which keeps it propped up at about a 60 degree angle.  Much easier 
to see, too!
