@Mark4470 , I was not familiar with Retinopath and how it affects the performance of a riflescope, so I did a bit of research rather than just throwing propaganda in a response.
As I see it, it reduces the sensitivity to contrast and creates further issues in dim light. There is also the problem with glare and lens flare.
To address those issues, you need the best contrast possible in a riflescope, high light transmission and flare control to handle stray light when shooting close to the Sun.
The March Majesta would definitely help with those issues, but I would suggest a few things. The advanced coating of the lenses provides the maximum state of the art light transmission on all wavelengths, there is no color tinging or hues in the Majesta (or other March scopes) and with the CA (Chromatic Aberration ) virtually eliminated by the Super ED lenses, the contrast and sharpness is unmatched in the Majesta. The coatings also virtually eliminate stray light and flares. March is well-known for that quality. I have shot late afternoon matches in Lodi when I had to hide under a towel just to look thrrough the spotting scope and the riflescope, and my March was sticking out from under the towel and I never saw any flares.
I would suggest you use it at 60X or below, above that it will be a challenge for you. 60X will also provide you with a nice wide view of the target. It will be majestic. I would also keep the sunshade on, especially if there's plenty of sun in front of you.
As for the reticle, I designed the MTR-WFD for all shooters of all ages, but I am 70+ years old and I made sure to put cues for reduced vision shooters, while not obstructing the acuity of others. The central dot is quite small, but the surrounding circle with its spokes make it easy for me, at least, to see that little dot. If that is too difficult for you, you might consider another reticle for the Majesta, but I think the MTR-WFD will work.
Lastly, if you do get the Majesta, make sure to install the included inner wheel on the side focus knob as it increases the granularity of the side focus control. I have the 3.5 inch wheel installed on mine to help with my arthritis and even more granular control.
Good luck.
