RGP contacts gave me my best astigmatism correction. A correct glasses prescription can be a close second. Astigmatism correcting soft contacts can be good, or can be horrid. I quit all contacts years ago, so am wearing glasses daily. I use a low power bifocal for daily wear indoors and at night, and non-bifocal Wiley X sunglasses for driving, shooting, tennis, hiking, and most other daytime outdoor activities.
I still may get tired and get doubled images, or fuzzy view if I’ve been on a screen too much.
Red dots haven’t worked for me, but I haven’t spent a ton of time with one yet. I suspect I’ll do okay at closer ranges with a large dot or circle on a pistol. Not sure about rifles, but I’m mostly shooting with scopes on rifles nowadays.
