These are the things that help me: Earplugs. I prefer these ones https://www.amazon.ca/3M-Non-corded-Disposable-Earplugs-Pairs/dp/B000I7LH8Y but you might have some luck with Loops as well. I would like those except they don't fit one of my ears very well.
Light-filtering Glasses. Sunglasses are good for outdooes, but I also have a pair of FL-41 coated glasses. They are meant for migraine sufferers, but I swear they make processing easier when I wear them. https://www.theraspecs.com/fl-41-glasses/
