Hi there,

I'm interested in going scuba diving but I am shortsighted so usually
I have to wear either glasses or contact lenses.  Do diving holiday
companies make any provision for this?

Any advice would be greatly appreciated.  Thanks

"Diving holiday companies"?  I'm not sure what you're talking about
here...

In the sport of diving, there are a couple of companies (or individuals)
that you will deal with...

1.  The shop or individual that teaches you how to dive / gets you
certified.

2.  The shop or company where you buy your dive gear, although some dive
gear is rentable if you so desire.

3.  The shop where you get your air fills.

4.  The shop or boat that arranges provides the transportation to the dive
site.

Not all of these have to exist for all divers...

Here's some notes that I've made concerning SCUBA certification...
http://grumman581.googlepages.com/scuba-certification

Depending upon how bad your eyesight is, you might want to consider
wearing contacts with a normal mask or having a prescription mask... This
has been discussed quite a bit around here, so you can search the Google
Groups archives for previous threads about this...

I am sure the dive shops will be happy to accomodate you.

They can sell you prescription masks, or even special contacts
for underwater use. All at a reasonable price of less than 10 times
a normal mask or soft contact set.

Maybe you should tell everyone else this...

If they are wrong, I'm sure that they would like to know it so that they

perhaps does not have lat/long coordinates associated with it and they are

Well, 300 miles probably seems a bit larger to you folks than it does to
us here in Texas...

Since you didn't know that there was a Ripe in East Sussex, perhaps you
can't use this as an excuse to call us yanks "insular"? <snicker>

If its any use they are 70 miles out with my location - which is a lot
of population in the overcrowded UK.

It doesn't, I've never had a lot of joy with these positioning tools -
at best they give the region covered by the ISP - which might be great
if the provider is Rhode Island Telecom and deals with that area alone-
but here in the UK an ISP might cover 1 million people in 200 square
miles- on ONE of his franchises alone.

Ahh but Ripe is one of about 16,000 minor villages (about 10 houses)in
the UK, and I can't knw them all. Now if it had a dive site! ;-)

70 miles isn't even all the way across town here in Houston...

I find they work well enough most times... Even in this case, they
narrowed it down to an area around the southern part of the UK... After
checking it, I suspsected that at the very least, the terms used over
there are different than here... We would call it "nearsighted", not
"shortsighted"... Over here, the term "shortsighted" is used to mean
"lacking foresight" whereas "nearsighted" is used as a term for someone
needing glasses for viewing things at a distance... Although the
dictionary does give "nearsighted" as an alternate definition for
"shortsighted", in practice, it is rarely, if ever, used that way over
here... It also explained the phrase "diving holiday company" which we
don't hear over here...

Supposedly, we speak the same language... <grin>

Ahhh, but you see, that's what makes us different... If you had posted the
name of some small town and claimed it was in Texas, I would have looked
it up because I know very well that there a lot of different communities
here and the odds are that there might be one with any particular name on
it... Hell, we even have a London, Liverpool, Manchester, Tunis, Naples,
Milano, Paris, and Moscow here in Texas...

There's two scuba divers who live over in Cowfold (Horsham, West
Sussex), if that helps :-)

I'm not in Cowfold - its where a couple of friends of mine happen to
live.  I've just enjoyed the village name, and I've been invited back,
as they're looking for friends who are willing to learn how to do
horsehair plastering.

And carry some spares or glasses.  If your mask comes off under water and
you open your eyes, your contacts are sure to float away.  If not you may
want to ditch them anyway as they can get contaminated by impurities in the
water.

Depends on just how short-sighted Jim Boss really is.  When I first started,
I didn't wear my contacts whilst diving because the water magnifies 25% or
so and that took care of things to a certain extent.  After I had more
confidence, I began to wear my contact lenses.

I never lost a contact lens, though once or twice I would think I had
because with a bit of water in my eye would have the contact float up on my
eyeball.  I just had to blink out the excess water a few times and the lens
would float back down into its proper position.  That said, when removing my
mask, I always squinted a bit to make sure the contacts didn't float away.

As for your comment about "ditching the contacts", I agree.  Get the daily
disposables.

I'm nearsighted - I have a mask that matches my prescription that I wear
while diving.

You can buy stick in lens from most scuba shops really cheaply.

(They stick in the mask, not your eyes btw!)

I highly recommend disposable contacts if that's an option. I've been
diving with them for years. I can even remove my mask with them in (and
put it back on, smartasses). Of course you can't open your eyes
underwater, but personally salt water stings me too much for that anyway.

My disposables come in individual little bubble packs. I always carry
about six spares in my kit, so even if I both on each dive I'm okay for
the day. But I've never lost one yet.

See if your optometrist can get you some...it may be that you wouldn't
be able to wear disposables for normal use (if you have astigmatism or
something like that) but if you explain you'd only use them for diving,
he might cut you some slack.

Otherwise...get custom contacts and be careful with the mask, or a
prescription mask if you don't like sticking things in your eye (took me
a while to learn).

Good luck!

That's the 2nd best option.  1st is lasik.

I'm not so certain of that... It depends upon how bad your prescription
really is... Mine is around -1.25 to -1.50 and I can get away without
prescription lenses in my mask if I want... It's nice having the
prescription lenses when I get back on the surface though to be able to
see the boat or shore... <grin>

The Navy is pretty picky about what type of eye surgery is allowed for
pilots and divers / special warfare personnel... If I was getting eye
surgery, I would definitely consider something that the Navy has
confidence in vs whatever the latest craze might be...

http://www.usaeyes.org/lasik/library/navy-prk-fighter-pilots.htm

Since as you get older, your near vision also goes, getting eye surgery
for far vision only solves part of the problem... You'll probably still
need to get reading glasses eventually...

I figure that as long as I'm wearing glasses, I have eye protection for
those miscellaneous things that seem to go straight for the eyes -- bugs
when riding a bike, chips off of chisels when hitting them with a hammer,
etc... All I have to do is look at all the nicks in my lenses when I get
ready for a new pair of glasses to realize that it is probably a good
thing that I wear glasses...

Wearing contacts under a normal mask enables you to see just as well
as you would with naked eyes and a prescription mask.  Same thing with
surgically repaired eyes.

So far, it's a tie.

Once you take the mask on, those with contacts or repaired eyes take
the lead because they can still see.  

By the way, young feller, I'm familiar with the reading glasses
situation, since I'm in it.  I was with contacts and am with repaired
eyes.

I needed reading glasses immediately upon having the lasik.  I still don't
regret having it done, but the short vision sucks.
