If I wanted to add a mirror layer on the outside of the lens, would it affect the efficiency and purpose of these glasses?

Other than lowering the overall level of light -- which means you'll need brighter light -- the effects will be the same. -Mark Changizi, co-inventor, O2Amp

Sorry, can't help with this question as I was a personal buyer for this product to help the contrast with my vision.

I am don't sure. I the internal part have a cushion added than not permit remove the lens. And in the front i can see the bordet of lens.

Provided you can completely cover the lens port and no other ambient light can get in I can't see why it wouldn't work. These are great for getting white balance, just point it at your light source, shoot and set custom white balance.

I'm not an expert, but to my knowledge, lens protection is main purpose. No added value to photo using clear glass. Since it's an extra layer of glass, there will be very slight impact on light transmission, but I certainly don't have a finely calibrated eye to see it with my camera and photo's I shoot. If you already have UV filter on your lens, you don't need to add NC.

I don't know why they couldn't? I would call up to your eyeglass place/Doc and ask them if they can to be sure. They would probably have to make custom lenses though, which may not be cheap, granted of course you already have the frame. I know I have brought in frames I have had to an eyeglass place and they made new lenses, so hopefully should not be a hassle.

Maybe. You'd have to try it. It probably wouldn't be a great fit, but it also depends on how bigyour glass lenses are. If the lens would fit inside, you could probably cut notches for the framesto make it fit better. Or maybe enlarge the cup to fit your glasses.I wear glasses, but I don't need them for the viewer.So maybe the diopter or whatever it's called can be adjusted if your astigmatism (?) isn't too great.You could try it and return it if it doesn't work. It's REALLY nice, though, and I wouldn't wantto film without one. (although I heard they weren't making this anymore -- or maybeit was just the model I got) Maybe. You'd have to try it.

Yes, you could actually. The stock lenses are not permanently glued or attached to the frame.They can be removed, and therefore put prescription lenses in them. I would as a matter of fact recommend doing this because the stock lenses are in fact somewhat blurred, this however outbeats the purpose of the glasses. So, yes. Than you and good luck :)

There is a lock somewhere outside the lens near the body. This might prevent you from changing the focal length.

Yes. The only thing about it is that when it is pulled all the way back, giving the widest view, the artificial extension of the lens will cause the edges of the lens to show up in the frame. Similar to what can happen when you put on a lens filter without a step-up ring.

You will need to purchase a adaptation set. I previously had one for other lenses/filters, so it wasn't a problem, but I can see where this might be frustrating if you did not have these.

One more thing, unless you have excellent light collection, I'd be careful. Both of these lenses absorb some light, and at maximum magnification the image may be too dark.

this shouldn't interfere with any portion of focusing either in or out of focus regions. If you put this to its fullest setting you will be left with a very close to black out filter. What you will notice its that you will probably have areas off uneven filtering the darker you set the filter.

The info given on this filter lens are as follows. the fully coated surfaces increase light transmission and absorb almost all range of uv rays to give clearer and sharper picture with less haze. so i will say yes

I would think so. Depends more on the lens you are using. If its off a little bit it wouldn't be hard to modify to make it work.

Not too bad to change lenses..a siff firm grip and steady should do it.....will not fit over normal glasses...unless you were colonel klink...with an eyepiece!!

The lens I have are glass, and metal rings. They can turn for different effects.

If a person wore corrective lenses, it would be smarter for them to get the coatings offered by their optometrist.So changing the lenses out of these glasses would just give you ugly frames..........
