I got these sunglasses, one pair in gray and one pair in brown. Gray for sunny days, but for overcast days I prefer the brown instead. I think I got 2.0 for the bifocal part, but the strength would be up to you.

I have also bought some clear ones at a safety supply store, but rarely wear them unless it is raining out or after sunset.

I can't imagine trying to read a computer or GPS or anything close up now that my eyes are 64 years old.
