Need more clarification….. For patient use or personal use? Are they goggles with a strap or safety glasses? Was it a CE course? Where was this meeting at? Maybe you could call the place the meeting was held and inquire who what when and where from them to help you find the information you seek.
Safety glasses no strap I have loupes but not crazy about them. I did call the speaker and she did not contact me back.
