As a life-long customer of John O'Connor from back when it was just his Henderson store and the optometrist was just John himself (he's retired now, still owns the stores - used to be a Visique franchise), I can say that the staff there are always great, spectacularly helpful, and I've never had them try to make a pointless upsell (didn't even try to sell me Transitions, though they did recommend the different materials when it was clear my prescription was close to a centimetre thick) Lenses are quality ones by Hoya and frames range from the standard cheap all the way up to pricey designer, but I've also never had them try to spin a yarn to get me to buy the designer frames. I note their way of protecting themselves from this costing too much is to limit it to prescriptions between +6 and -6 - I wouldn't even be able to use this deal (-7.75)
I too was once a client of John O'Connor's. Around 7 years or so ago my work occasionally took me out to Henderson and one day, out of the blue, I decided to replace my glasses and John tested my eyes. Great guy and it was very obvious that he cared a lot about patient health.
Wasn't too impressed with the staff member who helped me chose my ultimately uncomfortable and poorly fitting frames, however. In the end I had to abandon that pair of glasses inside a year. That combined with JO not being that conveniently located for me meant that I haven't gone back. JO actually was one of the optoms that I phoned to price up my lenses and they quoted a staggering near $600 figure for what two other places quoted at around $350 for exactly the same things (1.61 Hoya hi-index with AR coating and transitions). The explanation (to be fair I am not 100% sure if I have remembered everything) was that my lens would have to be custom cut and my Oakley frames would be difficult.
Realistically speaking, from what is physically apparent on the outside, Oakley semi-rimless seem to work no differently to others. Yet I noticed a persistent pattern of many optoms claiming that there would be extra work and how it's complicated etc to deal with Oakley lenses to justify the higher costs. Yet the four places that I received definitive (i.e. optometrist confirmed) reasonable quotes and helpful service out of (Milford Visique, Eden Quarter and Visique Henderson) all confirmed that they could see no issues and would not charge anything extra beyond what their lenses were sold for at retail prices if I desired no significant custom alterations beyond adding or adding to lens depth in terms of the demo lens shape. My little adventure suggests to me that a lot of perceived brand name chasers (I really am not one -- it's just that O offers a unique blend of my preferred styling and almost perfect fit ever time) are taken for a ride by many places that think of us as well-to-do and too stupid to ask around.
I have to say the optom/owner at Visique Henderson also came across as a wonderful chap.
