Yeah you don,t get those intense clear blue skys ,like we get down here in SA, you have afair amount of cloud cover , due to the humidity so your transitions would be constantly changeing, from sun to shade , and visa versa... i .have a problem with them at work , if i walk out of the store ,into intense sunlight ,then realise i have forgot somthing , and walk back into the dark ness you have a period were you are blind , untill the lenses clear ........mm

Eh? I assume you don't mean Brisbane as a lot of the year is intense blue skies there?

Yes but you need chill in the air and no humidity for transitions to work properly. They seem, to me anyway, to be a total waste of time here (me here not Aus here).

Fair enough, don't know much about them. I guess they would work the whole sunny winter at least. And the summer temps aren't as high here as Adelaide...don't they have an issue with higher the temp less dark they go? My bike shop guy told me you have to pay double and buy the really expensive photo-chromatic sunglasses to get one's that go really clear in the dark and dark in the light. But he is prone to telling me to buy things that cost double

They'd be working a treat in the UK at the moment Also over the period of a couple of years they tend to stop reverting to clear but stay tinted (not dark but not great) and are slower to change but I found they were slow to change in our climate anyway. I think (not sure) that Transitions are a step up from photochromatic, they're certainly not cheap. I don't know the best idea for a prescription wearing bike rider. Transitions also don't work well behind a car windscreen because of the polarisation of the screen so you may have the same issues with the helmet screen.

I find it easier to just wear my sunnies as soon as I leave the house and hope I'm home before it's dark It's a bugger being short sighted and not able to have lazer or wear contacts

Do a bit of a search for on-line sellers.
I'll be careful not to rubbish the store or promote the web site......

Maui Jim sunglasses in my local shopping centre $456.00
Found an on-line retailer (in Australia) and the price was $256 + $19.95 P&P.

I appreciate the on-line store does not have the overheads and I was very appreciative of the friendly sales staff at the store. Also it WAS great to try them on... felt really guilty to buy them on-line in the end as the sales staff were very good.

Shouldn't worry about it, that's how most people find out what to buy via the internet, they check out the item 'physically' first and then find the best price. If you're really lucky (or clever) you will then get the real shop to price match the internet shop but not many will do it. It's a great feeling when they do though
