I expect I'm gonna have a problem with my varifocals. I think I'll need new glasses.
Yes, you will, it's my biggest hassle riding a recumbent. Still not really solved 1500 miles in.
I also have a pair of distance glasses with big lenses (think Dennis Taylor) which I got for driving because I have 4 fused vertebrae in my neck - so not easy to turn my head to look around. I can ride the recumbent in these - which gets over the blurred world you see riding a recumbent with varifocals.
But, then you have the problem of reading the cake menu at the cafe stop. And the big lenses let the cold draughts in at this time of year around the lenses and make my eyes water - particularly at night - so I can't see anything with the distance glasses either.
Fortunately, I'm long sighted in one eye and short in the other (years of looking into a rocks microscope with one eye and drawing with the other) so I can
almost manage without glasses on a bike. I've been trying out these:

Bought a pair in clear and also smoked. They fit close so that stops the eyes from watering, but reading the cake menu is still a bit of a challenge. Maybe I need to take my varifocals with me in a case (something else to loose..).
So, it's a real conundrum. On a par with fitting bottle cages, seat back bags, lights, mirrors, Garmin.... I could go on. It gives you something to think about (and spend money on) on these long wintry evenings! Recumbents eh? Don't ya just love 'em.....
Good luck with the trike!
