my preference are contact lenses.

much due to the fact that i have severe astigmatism (600++ on one eye) hence prescription lenses are rather hard to come by.

not to mention that shud my mask go "bang kruuk kraaakkkk", i can still use my spare one.

what i did was consult my optician...i said i need to get diopters for my mask and she converted the degree to the + + thing for me.

usually they do it for free. after sales service.

Actually reen, i doubt that the diver will encounter problems with their vision underwater.

Only that its kinda hard to get prescription lenses for severe astigmatism cases.


But then again, i could be wrong.

haha.. true true.. but in my case.. it's a bit different. i'll have to wait until i go back then only find the slip and go to the optician.
i thought there is an easier way.. just calculate and get that thing here... hehee.. well, guess i'm wrong :)

thinking of doing an eye test here... wondering whether it's expensive or not... hehee
heard that medical bill will come to a very big amount if ppl like me go to see a doc just for a simple fever/flu...
cheers...

i use daily contact lenses so the issue of storing and cleaning doesn't arise... but i'm not sure if it is suitable for ppl with astig..

As ffor the lense displacing... well with time you'll get used to it...blink often... the lense displaces when the eyes are dry... blinking helps prevent that... If your mask gets flooded...u do not have to close your eyes... just squint a little bit while you clear it... I can even remove my mask and look around...no problem :)
