The issue that arises is when prescription glasses are needed for driving. Yes, you can get prescription sunnies – maybe even with polarised lenses. However I have not found any with a wrap-around to match the Cancer Council version but these are not available in prescription.
My solution was to attach my prescription distance glasses (with the arms removed) to my preferred sunnies. I have been using these combined glasses for several years.
Sure, it may look a bit agricultural but it works. The main combining structural member is a cable tie in the centre. A small blob of Blu Tak at each end completes the stability job.
