Here is my problem. Over the past 20 years, my arms have been shrinking every year, and each year it has become more difficult to read.
I wear cheap lightweight sun glasses most of the time when hiking. I usually carry inexpensive dime store readers, very small and light in my pack. But at almost 2 ounce with a case, it is a single use item. It is not practical to bring my normal glasses, which I would probably break.
I checked with my optometrist on some prescription sunglasses. Expensive and not lightweight.
I found some Maui Jim Ho okipa Sunglasses in bifocals with 1.5X readers. The reader part of the bifocal placement are a lot lower than normal glasses so it is easy to hike in them and see. I normally wear progressive lenses, so it was easy to get used to the bifocals. Now I can see a map well and do other eye-squinting tasks easily. The glasses are poloarized and were $199 from Backcountry.com.
Glasses weigh .7 oz. Comes with a cleaning/pouch combo at .3 ounce. So far, so good.
