Thank you for your suggestion. I have had three broken noses and deviated septum so I prefer glasses with adjustable nose pads. Based on replies, it does not appear that there is anyway to determine online which frames have spring hinges and which do not. I guess I will just have to make a list and find somewhere that carries oakley to try them on or look at them to check out the hinges. Wish oakley stated in their description the type of hinge in a way that identified type of hinge such spring or standard or whatever are industry standard definitions of the types of hinge designs. But, I will just keep looking. Thanks again.

My Base Frame R have what I believe are spring hinges.
My older carbon plate and tin cup frames have hinges that open to a fixed position. The frame was adjusted/bent(the temples/earsocks)for a tight fit which seems to hold the frames more firmly. The frame then flexes for any movement necessary past the open position when putting them on or off.
Unlike the spring hinge which allows for movement past the open position which seems to allow the glasses to slide when I get a bit sweaty along my face.
Thank you for trying to help.

New to the forum.
How can I quickly tell the hinge style of an Oakley frame when looking to buy online? I have worn Oakley glasses for 30 years. Technology is evolving. But, I prefer non-spring hinges as the frame can be adjusted tightly so as not to slide off when active and looking down while sweating. It seems most frames now have springs for comfort, but do not seem to work for physical outdoor hot environments to help keep frames in place. Thank you
