Eye relief?

Eye Relief: How far you can hold the lens away from your eye before the image distorts. The better the lens the better eye relief.

My mistake, just reaslised you werrn't aksing what it means, but what it is for this device

More to the point; The shorter the eye relief the less recoil the rifle must have. A longer eye relief allows use on a higher power rifle.

 

[Forest fella]

Well the Rubber eye piece is about 1 1/2 inches long,

 

[Forest fella]

Eye relief?

Do NV scopes actually have eye relief? I thought the eyepiece end was a little video screen?

On a hard recoiling rifle all optical scopes need eye relief - otherwise you get an almighty smack in the eye when you pull the trigger!

...and yes, I have seen that happen more than once to inexperienced people setting up a new rifle Claret everywhere.

I did that when I was starting out and I agree... with Claret everywhere too...

That's what I was asking, I thought NV scopes were only optical at the objective end. TV screens dont produce an exit pupil like a lens does. No? No exit pupil, no eye relief and you can be as close or as far away as you feel you need to be?

 

[Martyn]

See here....



When you look through the eyepiece you are looking at an image projected onto a phosphor screen, not a collimated pinpoint of light through a lens. No lens, no exit pupil. No exit pupil, no eye relief.

I understand your point Martyn, but

How is riflescope eye relief different from other optical device eye relief? All optical device users must be concerned with FOV perimeter shadow. However, a shooter must be even more concerned with eye relief for another reason - recoil. The eyepiece rim will impact the shooter's eyebrow during recoil if the eye relief is too short. In severe cases, the eyepiece rim will gash the shooter's eyebrow. Therefore, gun scopes are designed with longer eye relief than most optical devices - between 3 inches and 3+5/8 inches depending on the model. (Handgun scopes have a much longer eye relief than even riflescopes because they are normally aimed at arms length.) Yes, dealing with FOV perimeter shadow is frustrating. Dealing with recoil if eye relief is too short is hazardous.

So whilst it may be technically possible to move the head around and obtain a perfect image at a variety of distances, there will be a minimum safe distance between the eyepiece and the eye. In shooting circles this is likely to be understood as eye relief - even if this is perhaps not a technically correct expression. Contextual validity and all that.

It may be possible to have near zero eye relief - but it would be extremely unsafe on some rifles.

So then the eye relief in this case would relate to the rifle its used on and not the scope itself?
