Title: Wearing Specs, can still dive?
Post by: fishor on 21 Jul 10, 08:36
Hi,

New here, been thinking of taking the plunge into the deep blue. Im short sighted at about 200degree either eye. Am comfortable wearing contacts or specs. Could i still dive if i need to wear specs to see far?

Another question, am not really a swimmer, heard that we need to take a swimming test. Would that be an issue.

Thanks in advance.

1st Question
Before I had my Lasik last year.... my eyesight was 675deg on my left eye and 500deg on my right. Wore contect for diving from 2004-2009. But due to age.... became "Hyperopia" (can't see near) when I wore contect. Therefore.... your 200deg is nothing to worry about.


2nd Question
How bad a swimmer are you ??

*Panic when feet can't touch the bottom of the pool ??
*Can't swim at all ??
*Can swim in pool for 10-20m without touching the floor of the pool ??
*Can swim longer till tried but NOT fast ??

A good Dive Centre (DC) or Dive Instructor (DI) should conduct a simple swimming test to see how comfortable you are in the water. Most likely asking you to swim a lap around the swimming pool on your own timimg. Since most, if not all scuba diver use Buoyancy Control Device (BCD)... which is a floatation device you wear that could be inflated on the surface like a float. Therefore... if nothing goes wrong, you don't even have to 'kick water' on the surface.... but slowly paddle to the boat.

I would said you need only be very comfortable in water (not panic)..... able to swim without floatation for perhars 50  metres (more would be better).

Just my 2-cents worth.....  ;)

I wore contacts when diving.. 375 both eyes.

PADI require you to be able to swim 200m or 300m with fins, mask and snorkel.  You can swim at your own time and can even stop for a while and continue (I THINK!!).  Need to be able to thread water for 5 mins.

In most cases, its not difficult.  With alittle training, should not be an issue at all.

In actual case when you go diving, there are almost no swimming involved.  You float around.. below the surface and on surface.  You only need it in an emergency, such as your BCD fail to inflate etc.  In any case, its actually easier then in the pool coz you have fins (unless you lose them!).. effort is minimum.

However, proficiency in water usually means you are also comfortable in water.  If you are not comfortable, chances you getting panicky is higher in an "emergency" or performing drills, thus may not be able to react in a proper manner.

You can wear contacts to dive, no worries. Even if you find contact are troublesome, you can buy mask and fix a prescribed lens. It cost about $50 per lens, but not too sure. Maybe those with prescribed lens can comment. But it save the hassle of contact lens.

Swimming is not a test. The Instructor just need to make sure that you are comfortable in the water. If you cant swim, just lie down with your head facing up. You will naturally float. Then use your hand to move around. I think this will do because there is not time limit for the swim.

p.s. I dont even remember taking a swimming test for my OW. ;)

Wearing contacts is no problem.
If you like to learn diving, practice your swimming 1st. Don't need to swim very well but it is important to be comfortable in water. Practice makes perfect...  ;) Good luck! Hope u learn to dive!
Would like to relate a story:
We were in Maldives, there was a whale shark in the water, most of us got ready to jump in with snorkeling stuff... A few were hesitant because they said they weren't good swimmers, they were afraid... The conditions were ok, the sea was calm... They had learned to dive (AOW) but had not learned to snorkel.  ;D

like everyone mention.. u need to be able to swim about 300-400m and thread water like 5-10min...

if u can't do it well... then i suggest u train up as you take the course... its not too difficult..

and hopefully u will be quite okay when u take your OW...

Reason why i think it important.. its because, you are swimming in the open sea.. not in a swimming pool.  in a pool, u can still see and probably touch the bottom.. that is not always the case in the big open sea.

there are current, and many dangers that are part of diving as well.

Ppl.. ability to swim IS a requirement for PADI OW course.  Swim 200m, if using fins, 300m.  Thread water 5 mins.

Other agencies, I not sure, but I'll find it strange if they will certify ppl to dive in open water when they cannot swim!

Being comfortable in water is not an issue for me as I was formally a wakeboarding instructor. But most of the time with my wakevest or what you would call a pfd. Only worry if I had to swim a certain distance within a time frame.

About the mask, was told by my friends to get my own mask and fins even for my open water test, for hygiene I guess. Could I get any mask off the market and fit them with prescribtion lens?

You can take ur time.. swim slowly.. no hurry..  ;D

As for hygiene, mask and fins are the least of ur concern.. these can be cleaned easily.  You should be more concern abt wetsuits, ppl like to pee in them.. and regulators, ppl vomits in them.   ;D ;D ;D ;D

Yes.... while ability to swim IS required for PADI OW course.... I also didn't do any 'test' when I was taking my OW in Thailand.  :P

Wah! Regs are too expensive now to invest in. If diving is in aur/dayang area, whats the water temp like? Would rash guard and board shorts suffice?

Water temp in Tioman, Aur/Dayang is a warm 27-29deg.... your DC would provide you a shorty (wetsuit). If you are young and fit.... or in my case, FAT..... then shouldn't be a problem wearing just rash guard and shorts.

Most ppl will start with Mask & Fins, Wetsuit.... later maybe BCD, Reg, Dive Comp... etc.

get your own mask and fins.. i think that mininum...

for your case.. i would get a mask first.. as your need to get one in your degree...

as for fins.. i would get after u taken your own water.. and using your open water to try out the different fins there is...  i know the temptation is to get a JET fins straight off.. but i think u can learn your skill first.. then get the fins next...  and dun just do OW only... arrange to do advance straight after... you get to dive more.. learn more.. and ROI on that mask and fins that you will be getting...

just enjoy diving.. dun worry about too many things...

There are advantage and disadvantage using prescription mask. 

You don't have to worry about losing your contact lenses but you'll have vision problem on the surface if you remove your mask.

Hi,

Just go for it. Best to be good in swimming which u will enjoy more but if not very good you still can enjoy diving so no problem. As for the mask juz go to the dive shop and they will advice u. As for personal equipment for me its more on hygiene and if u take care of ur own equipment it will boost ur confidence more, also will get use to it. If everytime u rent its like a new set to u, hard to get use to it. But its best to get after owd n c if u really like the sports then invest them.

yoz,

my own personal mask is fitted with prescription lens. I think most conventional design mask can readily accept prescription lens.... just check with the dive shop they might have stock for those prescription lens. The brand of the mask i am using is unidive...inexpensive and does the job well! hahaha

i was asked by my ow DC if i wanted a mask with degrees. but i can still see clearly underwater w/o aid even tho i wear specs. i believe a diver should be quite confident in swimming IN CASE of an emergency, there is somewhat something to fall back on to increase your survival rate. that being said, for me i believe swimming IS necessary. and how come you all thread 5min only, my one was 10min sia!
