I have a set of Oakley sunglasses (not cycling ones), and got my local optician to put some prescription lenses in them. It was way cheaper than having Oakley do the lenses. .
I am currently looking into new ones as my script has changed, but will not hesitate to go the same route. The price I was quoted was about $400.00.
Iāve had my current ones for almost 10-12 years.
