Hi Ian, Thank you for asking your questions!
You've said something very important, that deserves the group's attention: "What strikes me about this process is that I don't think everyone experiences subtlety the same way." How true! We have a very wide range of members, in the quality of our vision, the strength and complexity of our prescriptions, and the kinds of tasks we perform with our eyes. We need to make a habit of asking these questions, so that our discussions are as helpful as possible to a wide variety of people. You, for instance, have excellent vision which permits you to see and work with very fine detail. You require a minor correction with superb optics to do your work, and enjoy the vision you're blessed with. We have near-sighted members who do things like graphic design. For them, the chromatic aberration in polycarbonate lenses would be noticeable and annoying, but the rest of us might not even be aware of it, most of the time. On the other hand, we have windsurfers who really need polycarbonate or Trivex. Myself, I have poor vision, have had surgery for a detached retina, and am lucky to be able to see as well as I do. I have an unusual prescription, but fine-tuning and super-expensive optics are overkill for me. I'm thrilled to be able live a normal life, drive a car, read, and use a computer to communicate and buy glasses. I don't need to do close work, or pilot an aircraft. These discussions help us understand each other and our needs, as well as the technical details. How gratifying it is, to be able to do all this without being manipulated and exploited by the optical industry!
