what is the eye slit thingy for? sorry if that sounds like a dumb question

That is for shooting a sight line ,say to a pole about 600 feet away or a tree,then continuing. The lens is for Reading the numbers on the compass face,then shoot a bearing where you want to go

No I asked also. With a compass, you look through the eyepiece and and fix the compass wheel point to line up with a landmark you want to get to. You then have the direction, north, south, etc to follow the compass line on.

It's used for sighting the course you intend to follow. As you turn the compass to the magnetic direction you want to go the sight wire shows you where that direction is in the distance or on the horizon. It gives you a more precise reading to follow.

It acts like a gunsight and focuser. If you look through the slit, you can see both the wire and the distant object, so you can center the distant object on the wire. The wire is in line with the center black line of the bezel. Many persons may not see the wire and the distant object simultaneously because the wire is only inches from your eye, its very close. The slit also then works then like a pinhole eyeglass or Inuit snow goggle allowing the user to focus easier and see the wire too.

When you shoot an azimuth, you will line up that U-shaped notch on top of the lens with the base of the sighting wire and look through the lens to read the number off your dial. If you're trying to walk a straight line on a specific bearing (e.g., 325 degrees or N 35° W), you can find a landmark right on the wire and walk towards it. If you want to know the azimuth to a given landmark (or two landmarks, to triangulate your position), it's as easy as pointing your compass at it.

When you ate handling the rifle, for the eyepiece, you so.ply push the spring button and the cover flips up. You Dont want to have to find the button and technically push back against you to open the objective lens. You simply thumb it forward and it pops open. It makes a lot more sense when you actually use it.

Shouldn't it be in the box? Actually the use is quite self explanatory. 1. The switch: forward = incidental light, backward = transmitted light, middle = off 2. Lens touret: Rotate to 2x or 4x positions till it clicks into position. 3. Eye pieces: Two sets of eye pieces 10x or 20x. Loosen the small retaining screw on the side to change the eye pieces. 4. Open or close the eye pieces so you only have one picture with both eyes open. Cover the adjustable eye piece, and adjust the focus knob till the picture is at the sharpest in the other eye piece. Switch the cover to the non adjustable eye piece, look through the adjustable eye piece and adjust this eye piece till the picture is sharpest. Now you have adjusted the scope for both eyes and will not make your brain work any harder than it has to. My most enjoyable moments: share my learning with my grandsons.

No there aren't. It fastens in the back with Velcro. The eye hole is actually one hole. The picture just shows the top pulled down to touch the bridge of the nose making it look like 2 separate eye holes. I suppose if you wanted to use a little thread, you could stitch it closed like above.

Not 100 % sure I understand the question... but it is really just an adapter/mount... just to change the threading to use different lenses...

I don't know because: 1) I couldn't leave it on very long as it pressed too hard on and around my eyes. If I loosened it, it was not touching the area I wanted it to touch. 2) I never used it again.

You shouldn't have to. Perhaps if you just bite it maybe the slit is there but needs to be "opened". .??

Main purpose of this privacy screen is to protect your information displayed on the screen from the person who is setting beside you. I may reduce the glare from the screen when you are seeing it directly but not sure that this is the best product that I am aware of for reducing eye strain from laptop use.

The eye piece is a separate piece. I remove it everytime after I am done using it. I imagine it could be swapped out.

The adjustable flared eyecup is very comfortable. Its adjustable to use on either eyes. Also, if you use glasses you can twist up the flared for added comfort and viewing plus the image looks for more clear when the eye relief is flared.

I'm not entirely sure, but I imagine it means these glasses don't magnify anything. They just help protect your eyes from the strain of looking at the computer screen for hours and hours... They sure seem to help me.

I'm not sure if that's what it's called, but there is a little plastic that wraps around the sides & pretty much covers the entire area around the side of my eye/temple. I use them when I'm using the electric trimmer or edger outside & I feel safe in them.

you need to look at the back. I dont remember if it has a rectangular or circular eye piece. If it is circular it works

Sorry about the first response...The eyecup is definitely designed to go around your eye comfortably without glasses. You can still look in there and get a pretty good view while wearing glasses. You'd probably have to try it out and see.

No this sight is meant to be used with both eyes open for a full range of view and has no eye relief. You can adjust the raticle for brightness which is nice when you are using it at different times of the day or when it's cloudy. I'm out in my hunting blind right now and it's overcast so I have ithe brightness dialed down which also makes it more difined. Hope this helps

It blocks out maybe around 15-20% of the light from the screen when viewed perpendicularly from the screen. Its main use is to deter nosy eyes from the sides. If 15% reduction of glare from the screen is good enough for you, then it probably gives u a 2 in 1 deal. ;)

My eye doctor recommended it for me. I have meibomitis- a chronic condition of the eye-close to dry eye problem. It helps my condition a lot.
