where can I get repacemet sunglasses lens that clip to the fron. Most of mine the clips broke.

On the Rapid Eyewear website, in the spares section

Not sure that I understand the question. These are glasses that have an insert for prescription glasses. The prescription, assuming you have one, can be e-mailed in to the maker in England or shipped with clear inserts and taken to your local optician. I recommend having the provider in England do the prescription. I did and am completely satisfied. Love my glasses. (actually the glasses are prescription with polarized overlays that clip on to the glasses and can be flipped up with out removing which makes them easier to clean and much more secure)

Hello, Do you still provide prescription contact lenses fitted on order?

We do provide this service but it is not available through Amazon.

@ seller: is the only difference between this product and the pro performance plus version the inclusion of clear lenses w/ the latter?

Yes that is correct. This product will actually be revised very soon, whereupon it will become the glasses and a pouch only, i.e. no extra lenses, strap or carry case. Obviously the price will be cheaper. That changeover will occur in the next few days and so I would suggest you buy this item fairly quickly if it's the one you want. if you don't want the extra lenses, the revised package may be more suitable and so you could wait for that
