Hi, my partner and I are visiting Egypt in a few weeks and plan to do a lot of snorkling. My partner is looking to purchase a prescription mask (she has a negative prescription), my questions are:

1) which lens are any good, the fitted type or the stick in lenses?

2) does the refraction of the water effect the strengh of the prescription required? ie does it need to be the same as her glasses prescription?

3) any tips or general advice when purchasing a prescription mask for snorkling purposes?

Thanks in advance for your advice

Hi Moonshine,
If she's going to get serious about snorkelling/diving have a look at :-http://www.hydrooptix.com/
I use one and love it (i even have a spare) but I know some people hate them. You do get fantastic vision and no size/distance distortion and for me that's worthwhile.

Be aware tho that if, like me, you normally wear bi or varifocals, using a minus lens only, makes things like photography a bit difficult. I actually wear a corrective disposable contact in one eye (specially calculated by my friendly Specsavers optician!!) that corrects for my vision and then the mask lens and allows me to focus at c 40/50cms on the camera screen. It does mean I can't see a thing out of that eye out of water but, hey, life's full of compromises.
