Discussion: Good plan

You're on the right track. Yesterday, my distance vision was poor / slightly blurry - but it was good enough - orange & white flags were still easily seen, and very little "peering" at codes on them. Features eg fences, paths, veg boundaries are clear enough.

Running downhill thru trees & branches with one lense in is something that's hard to do well - I regularly scratch my ears as i can't see in 3D. But it's a compromise that, for me, after many years, works as well as can be expected!

BTW i don't wear the "single lense" more than 3 - 4 times a week. I wear my varifocal glasses, & have full 20/20 vision with them. They're great for sunny urban/ moorland O too.

Another option is to wear two lenses, but have one of them at a lower prescription than you might normally have. Enables me to maintain some 3D vision, whist still being able to read a map - with the help of my magnifier. Its all a matter of experimenting until you find the best compromise for you.

p.s. Agree wiith your comment about yesterday's planning. Our course was also far technically easier than it could have been, which was a shame.
