What you see is what you get with this model. I was surprised there was nothing with it to put letters on. Our local sign shop put vinyl lettering on it for me and said if I wanted to change it I could have him do separate vinyl signs that could be put on with velcro to cover the old sign. I think there is a more expensive option that includes what you are asking about, though.

I don't know of any. We make signs on tag board and laminate at Kinko's or staples. We make signs like saddle bags, lay over plasticade, secure with c-clamps or painter's tape. C clamps are clumsy but work.

The case does stick out past the lens a little which offers some protection. But there is no clear plastic lens protection built into the case if that is what you are looking for.

They are plastic lenses. If you order 2 identical sets in the different strengths you can unscrew and trplace the lense

Not sure, but don't think so. Too heavy for boats, and if plan to use on a deck with a tripod, they come with protective rubber eyepieces for lenses & a cover for dust if you want to leave them out if not raining.

No. There are vinyl plastic coated tips on the ends. I have poly-carbonate plastic lenses and have been using them for a couple of years without scratching the lenses

No, the lens has a scratch resistant plastic cover for protection -- in a sense it's a transparent lens cap.

They are plastic. In years past I had always had glass in all of my filters, and of course the glass is more durable... and much more expensive than the plastic. After reading several reviews, the reality finally hit me..."How often am I really going to be using these...really?? I decided that it wasn't going to be a great percentage of the time... and when I do, it will be for a specific purpose and series of shots... mostly on a tripod. So the chance of damage is minimized... and I just need to think about what I'm doing... it's not like a skylight or UV where, for the most part, you are leaving it on to protect the lens... ALL of the time. Filter storage is a sturdy fold-over design with hooknloop closure and the filters come in individual clear sleeves that are reuseable if you are careful with them... I have had no problems with the filters getting scratched so far... they are in my kit (3 different diameters to cover my normal lenses and 3 steps ea.) just for the eventuality that I find I am in the situation that I need them... for the price I couldn't beat them. Remember that in the early days of photography, as well as many pro's today, they used gelatin filters ALL the time, not glass.... so yes, they are plastic.

There is an outside thread on the lens so it should be possible to fit a UV filter to it.

If there is metal around it. The lenses stay put via a small magnet and they need something to attach to.

Yes there is but I would get a glass one instead of this plastic one. What you look at might not be as clear as a lens made of glass.

No they dont. I put them on when facing the sun and it's like not wearing glasses at all. These don't offer protection from sun just from computers.

Yes there are. I bought the Sigma polarizing filter and it attached securely onto the UV filter.

I can't find any but the lenses seem to be similar to lenses from other sunglasses. Mine came with 3 sets (clear, blue, and orange) so I haven't needed to look for new ones yet.

Yes I think so, they are supposed to be waterproof and they have "rain guard" coated lens's .

Yes, there is a multi-element shutter, which closes when power is off. I doubt it's "dust" or "water-proof".No separate lens cover came with mine.

I would say they are water resistant. They do have a rubbber gasket behind the lense but fully submerged for any lenght of time they might get water in the shell.

I don't know for sure if there are. I haven't seen any. I used to get a soft chamois eye cover for my old Arriflex 16mm eyepiece but they would be too small to cover or replace this eyepiece.
