EdifeelEdifeel Adjustable Glasses Strap, Anti-Slip Sunglasses Strap for Sports, No Tail Glasses Holder Cord, with Steel Wire Cable Eyewear Retainer (3 Pcs, Black)

These are adjustable, fit under hair for an almost invisible appearance and are very secure. I used them recently for a hurricane and evacuation prep. It was terrific to have my glasses on me all day long with no worry about where I'd laid them down or if they would fall off. When minutes count, this Made packing to evacuate so much easier.

I like theseI lost a pair of glasses in the Gul when a wave come from behind me, bought these to make sure that doesn't ever happen againSo far they work greatKeep my glasses tight to my face, as tight or loose as I want/need them

Take a look at the glasses arm on your glasses before you purchase. As you can see, it fits two out of 3 pairs of glasses I tried. The pair it didn’t fit has a much smaller end than the others. When the fit is right, the glasses don’t slip out but stay securely.I like the way you can lengthen or shorten the strap. It doesn’t stretch very far, but is long enough at the longest length to fit over my head. You can see in the last picture where they sit on my chest.Easy to use and doesn’t pinch my hair. And nice that you get three in the pack.

Chick and doesn't hurt your ears, doesn't not bother your neck as it falls down.

Small and well made, great for the boat

Work as expected, but not great. The "behind ears" piece adds on to the thickness of eyeglass temples/arms which makes me feel uncomfortable to wear... Maybe great when wearing for short periods of time, but at least for me it doesn't work for longer than 5-10 minutes.

Superó las expectativas

They are great, glasses doesn't slide down my nose anymore! 🥰
