So.........I went into this not knowing what I was doing really. More of an experimental thing since the lenses were already scratched up. Well, these pictures are kind of hard to compare the standard lens too due to no before and after shots (which I just thought of), or a second pair to compare with. It was actually really easy to sand down the lens, and did this without a dremel. The actual lens at the bottom is rather smooth as I used wet sanding to make sure it came out nicely, but in the process I somehow (and I was EXTREMELY Careful about this) got a nasty scratch on the left lens. I have NO idea how it even happened, as the lenses were covered with tape, but whatever. They are a beater lens anyways haha. Here's the result! Just as a reference, there was the Polarized Etching on the bottom left hand corner before I started this. Also, I used a disc, belt and oscillating sander, along with my own elbow grease with some 600 Grit paper. I'm afraid to go down even more, just due to how the frame has the lens in place, but it wasn't a bad first try. What do you guys think? Edit: Just a reminder, I am no robot. These are not 100% symmetrical nor perfectly shaped haha.
