2pcs Eyeglasses Holder Strap, Sunglasses Strap, Eyewear Retainer, Sports String Retainer, Adjustable from 9.2" to 14”, with Glass Cleaning Cloth and Screwdriver, Black

My review here is more for this style of strap, not just this vendor. After receiving the product, I immediately put it on my glasses and experienced the following observations.1) It is difficult to slip the strap ends over the ends of the temple pieces very far; mine is currently around 8 mm. It feels secure, but I am concerned that over time the strap end will loosen without my noticing and cause my glasses to fall at an inopportune time.2) The strap cord is fairly stiff making it harder to manipulate.3) Even with the pulleys close together for maximum length of the strap, it is not long enough to put on if I have baseball cap on, which I can do with the buckle style strap that I have normally used before.4) To put it on, I must use two hands because the strap attachment at the end of the temple arms prevents me from sliding the glasses on from the front with one hand. There is no way to put your glasses on other than bringing them down from the top of your head with both hands, after removing your hat/cap. Since I am normally walking a dog or carrying something when I am outside, it is very inconvenient to have to use two hands to take my sunglasses on/off when I go into and out of stores.5) I prefer to have the strap at maximum length, but that causes the cord to touch the collar of my shirt or jacket. The collar pushes up on the cord, which in turn pushes the glasses forward and consequently down my nose. I am constantly pushing my glasses back up my nose. If I separate the pulleys to shorten the strap, it becomes more difficult to put the glasses on (see item 4).Summary: I think this style of strap would be OK for someone who needs a sport strap to retain glasses during athletic activities, but for my normal usage, I am going back to the flexible strap with strap attachment buckles that allow me one-handed on/off application and do not require removing my cap (I'm outdoors a lot) just to put my glasses on over my head.

I love these. I got them to keep my plastic frame glasses from falling off while wearing masks. It does rub on my ear a little, but I'm willing to deal with that because my glasses would just fall off if I looked down at all while wearing a mask. I use these everyday because im basically blind without my glasses. I regularly reflect on this purchase as one of the best ones I've made. That sounds dramatic but before I got these my glasses were always falling off, sometimes in really not ideal places and situations.

The most annoying thing about glasses straps is the tail that goes down your neck and back when the strap is tightened. I wear safety glasses all day and at home would still feel that strap flapping behind my neck hours after removing them. THESE SOLVE THAT PROBLEM!- they fit well on the end of all my different types of safety glasses, and I’m pretty sure I could cartwheels in my glasses and not lose them. Also, these come in a double pack so there’s that bonus.

These are super rigid, so if that's what you're looking for, then they are great. They don't comfortably move from your ears to your neck, it's more of and uncomfortable struggle. Once on, the band quickly tightens to fit your head though. They stay on the glasses well and look nice if tightened to fit (otherwise they just stick straight off the back of your head).

This is a great product, extremely comfortable. I wear them all day long, and hardly notice them. I checked the product specs, and guessed at my the size of my glasses. It fits one pair of my glasses great. My second pair was too narrow to fit. But I worked around this by putting some tape around the glasses to increase the diameter. Now that pair also fits great with this product. lesson learned for me, use a measuring device to check your glasses. Or you may not be able to properly use this product.

This happened twice (breaking after first use). We ordered a replacement after it happened to my husband, who luckily didn't lose his pair, but I wasn't fortunate enough and the broken strap caused my pair to fall in a river. Both times we used it very gently and never pulled the strings hard. The strap got out of the knob for no reason. The very purpose of this strap was to PREVENT losing my sunglasses and it achieved the EXACT OPPOSITE. Don't buy any such holder, the sleek look is not worth losing a perfectly functional (and expensive) pair of sunglasses!

I'm getting old, so recently had to move to prescription sunglasses. We have a friend with a boat so needed eyeglass retainers - purchased these based on reviews and price and they are great, do the job. Easy to adjust the length so that in the extended position it doesn't protrude into a headrest (since they are stiff, not flexible like a shoestring). Easy to put on/take off the glasses, the end of my glasses are 6mm.

Concept is good but the end product fails to meet expectations. During any type of activity the restraint loosens so my glasses slid down my nose. It is okay to keep the glasses from falling to the ground but NOT intended for use during activities when the person is sweating and/or moving around. This design is a little cumbersome too. Better looking than those with a “tail” but lass functional.
