The field-tested Universal Fit rope eyewear retainer is made with patented molded tips that fit nearly any size of eyewear frame. The 5mm or 3mm nylon rope construction provides unique strength, durability and style.
Have a few of these and they're solid. Fit the fattest earpieces I have and still hanging after several years. I prefer the 5mm, but why, I really don't know!

Perfect for my dental loupes
I use my 3 mm universal fit retainer to hold my magnifying loupes for dentistry. I do not have much of a nose bridge, so this retainer is really whats holding my heavy glasses up and snug against my face. I've been using them for 1.5 years so far and they're still doing great. No adjustments needed. I would recommend using these too, especially fo the price!

Great
They were tricky to get on my ray band aviators but my boyfriend managed to get them on. Really good quality, not really even sure how you could improve

Good
They work good for me. Much better that the ones I had before. I can see that some glasses will not work with them but mine do, perhaps paying attention to what you are looking at would make a difference. Before I was always adjusting the Chums to continue working but these I never have to adjust.

Lightweight and great for active outdoor activities. Broke them in fly fishing.
