I wear contact lenses. They give me 20/20 long-distance vision, which is great for flying. Unfortunately, I am in my late 50s, and need reading glasses (when I wear my contact lenses).
For hang gliding, I face two optical problems. Firstly, I have trouble reading my vario or reading the frequency display of my radio. Secondly, after I land, unless I have my reading glasses with me, I can hardly make out the tiny font sizes of my smartphone when I send and receive text messages.
Last month I tried a friend's pair of sunglasses with little bi-focal inserts. Man, I thought! I gotta get me some of these!
The local Safety shop (where you buy hard hats, hi-viz jackets, ear plugs, etc.) had these for $NZ9.60 (about $US6.60) https://www.eskosafety.com/shop/esko-ma ... ation-1-5/
I tried the +2.0 strength bi-focals, but the +1.5 was clearer for me.
I tried them today in the air. See the 49 sec mark in my video

What a tremendous difference they made. Despite their cheapness, they fitted me really well. They aren't tinted, but they block UV light. There are no rubber skirts (that start to peel off the plastic frame after the first hot season).
I should have bought bi-focal eyewear 5 years ago.
