Reading glasses

Do the regular 'sports straps' not work for you in keeping the glasses in place when you're on your side? If you just don't want the side frames at all, perhaps you could unscrew the side frames from the glasses, and tie off a bit of thin guy line into the resulting hole (orange with reflective trim would be tres cool;-), and then attach some bungee type string to that to go around your head.

What about the style of glasses that have the flexible wire-like temple pieces that curve behind the ear and hold them firmly in place? I have found these to be completely stable in any position. They don't move at all.

Sounds good! But I'm not sure I know what you mean. I've never seen what you're describing, or at least I don't think I have. Can you provide a web link?

I looked it up. They're called "Comfort Cable Temples" and they wrap around the ear for a very secure fit. Here is a picture of a pair of sunglasses with this type of temple piece:

I'm confused to as what kind of lanyard you're using.

For fishing, I've held my sunglass to my body using a lanyard like this (for at least 15 years):

It's hard to see from the picture but there are holes on the ends of the cord and the hollow strap just slides over the end of the temples on the glasses. They kind of work like chinese fingers so if you try to pull them off from the strap end, they cinch down on the temples.

Anyways, if the fishing is really good and we're constantly bending over the boat to unhook the fish and release them (catch-n-release). Sometimes the glasses will fall right off your face.

So you just cinch up the cord lock in the back and it will hold the glasses tight to your head so they won't move when you bend over.

This should work for you in your shelter and it's light weight.

While walking you would just relax the cord cinch and let them hang on your chest.

BTW, I don't use the one I linked, it's just first thing I found when I googled "sunglass strap".

I also use one with my hiking sunglasses because it's just so easy to take the glasses on and off on a day where it keeps moving from sunny to cloudy.

I have this problem – I need reading glasses while hiking, to look at maps or screens or whatever, and also while fishing. And lanyards get tangled with the chin string on the hat, or the hydration valve, or whatever else I have going on. The lanyards also pop off – I've lost four pair of sunglasses over the past two years. I've had the regular kind that slip over the earpiece, the "hides" and some floating thing that only floats if it doesn't pop off and lose the glasses entirely.

I'm thinking the real solution may be drilling holes in the ear pieces. Maybe that's inviting strangulation but I'm sick of losing glasses and having to pull out the pair of backups.

Also thinking of getting http://www.stickonbifocals.com/ for my sunglasses. That should reduce the number of strings on the neck.

Foster Grant, sold in Walgreens, had "bifocal sunglasses" this summer in three "strengths" of close up vision. No polaroid lenses though.

Polaroid clipons, nice ones also at Walgreens and Walmart this summer, over bifocals are another option to reduce the number of eyeglasses dangling around the neck.

I have no experience is preventing them from falling off as your head position changes.
