I got the sun shades for my Athlon scopes, Not sure if its just my old eyes are not but I cant tell any difference with or with out the sun shade,,, Is it just to reduce the glare of the sun
if so it dont work on my scopes, I am talking about the 3 to 4 inch screw on the front of the scope,, Feel free to tell me what yours does for you,,
OK you can put this in the dumb question optics.. LOL.

Oh they work.
I shoot field target and sometimes those devious match directors intentionally place targets where the sun's glare just wash out the target and your cross hair. You look thru your scope and it's just one big blast of white light.

Learned my lesson after the first few matches. Now I got a sun shade on my scope and I bring a hat with a brim ...just in case.

I am facing east when I shoot from my bench to my trap at home. In the morning, there are times I just cannot shoot without a sunshade on the scope and a hat with a brim. I tried a honeycomb that came on one of my scopes and it did not do anything for me. But the long sunshade that came with my Arken works great. It lets me see the target when the sun is low in the sky and would otherwise produce too much glare for me to see.

In the afternoon I do not need it at all. If I was shooting north or south I probably would not need it either. If you do not have one for a scope you want to use and want to see the effect, tape some light cardboard over the end of the scope making a tube. Not nearly as elegant but functionally pretty much the same thing.

As discussed in the field target example, when you need them, they are very handy (but if I got caught without one I would look for a little cardboard and tape).

The primary purpose of a Sunshade is to eliminate off-axis light (any light coming at other than straight-in) from hitting the Objective Lens (the lens closest to the object being viewed). Off-axis light tends to "wash-out" the image. Sunshades can also reduce the possibility that light reflected off of the Objective will spook game, but they aren't nearly as effective as an ARD (anti-reflective device) of equal length. ARDs' have a honeycomb installed in the barrel of Sunshade, allowing an ARD to be substantially shorter in length than a Sunshade while still being effective at reducing or eliminating glare.

However, because an ARD's honeycomb partially obscures the objective being viewed as well as some light from entering the shooter's pupil, ARDs' can reduce image quality. The more efficient the design of an ARD the less image degradation. I've shot firearms with USO ARDs' on USO 3.2-17X[44]s and USO ARDs' on Schmidt Bender PMII 5-25X[56] and can attest to the efficiency of USO ARDs'. There is a slight image degradation, not nearly as much compared to Tenebraex ARDs'. I chock it up to Tenebraex ARDs' having a much tighter honeycomb (thus increasing the area occluded while decreasing the light entering the shooter's eye).

I use honeycomb filters to hide my sun scope flair from ground squirrels. Works great.

I deer hunt, late in the day facing the sunset they help a lot . Takes away most of the glare . Bang.

I'm glad you mentioned deer hunting with a sunshade. My question is this, in low-light areas of the woods can a sunshade lessen the amount of light transmitted through your scope diminishing image quality?

On my Athlon's and Hawke scopes it only makes the reticle hard to pick up but I use the lighted reticle when that happens. As far as diminishing image quality not for me ymmv. I'm also talking about FFP scopes

Depends on where the sun is / the angle the light is coming from
