SCWJTF 4PCS Premium Nylon Eyeglass Straps, Adjustable Eyewear Retainers, Anti-slip Eyeglass Chains Lanyard, Sport Sunglass Retainer Holder Strap for Men and Women's, with 2 Pairs Eyeglass Ear Grips

Do exactly as they are supposed to. I love the colors. I constantly take off my eyeglasses and sunglasses. I also kayak, and need to have a way to keep glasses tethered around my head. These are nice and thin, and grip the thinner wire frames tight so they won’t slip out. A good product that comes in some colors as shown.

No abrasion or irritation on the neck. Only had them about a month so, hopefully, the soft flexible plastic ends will last a long time before they get denatured (get brittle) and break. The only drawback with these is the little metal band that keeps the end snug around the glasses temple slips a bit sometimes, allowing the end to slide off. I flattened the little metal band with pliers after snugging it up on the temple & it doesn't slip off any more. Great low price. 5 stars

I have a lot of good to say about these (more details below). The thickness and length of the clear, rubbery pinched loop that slide over the ear piece of one’s glasses will not keep enough tension to prevent it from sliding off again shortly. I found though that if you do the following, the double loop has the right amount of tension and doesn’t come off on its own (so far), fingers crossed). See photos above: 1. Slip ear piece through the lower end of the double, rubbery plastic loop (the loop attached directly to the black cord) 2. Curl the double, clear loop so you can pass the eyeglass ear piece through the upper loop (the loop not directly connected to the black cord) 3. Slide the two ends of the loop past the thicker end of the glasses ear piece and tighten if necessary by sliding the silver “spring so the upper loop tightens 4. Repeat for the other ear piece with the other end of the cord (the double, clear rubbery plastic loop) I found these to be well made. The cords are a nice thickness, the clear plastic loop is thick enough that it shouldn’t break through easily, and the silver spring is wound tightly and is thick so it shouldn’t fail soon. Unfortunately, the cord is shorter than I prefer, but still usable.

You have to keep tightening the loop as it keeps getting loose and can fall off. Just like the cheap ones I used to pay a dollar for. The ear pieces are useless for me as I can't get the arm through the tiny hole. If you don't mind having to keep tightening the loop I guess they're OK but only because they're not expensive. Of course, your glasses could simply fall off. Update: I just lost a pair of reading glasses. You know what these things cost! I blame these worthless pieces of garbage. They simply will not stay on the glasses! PERIOD! Do not buy this product!

First, the lanyards are great I wish they were 4-6" longer but they are ok as-is. They are nice, thin, light weight leather in 5 colors: Black, Red, Gray and Tan. The red is actually pretty nice looking. The part that goes on the arms of the glasses can be pulled good and tight so it works with very thin-armed glasses and doesn't slide around. I prefer these over the thicker, nylon braided lanyards so common. These are more comfortable and less noticeable. I'd buy these again in a minute unless they offered another set that was longer, I'd buy those instead. On to the goodies. I LOVE the keychain precision screwdriver. Unscrew one end ad it's a precision Philips and the other end is a precision straight blade. Very cool. I have another that came with an enclosure I bought for an SSD drive and now I have 2! These are super handy if you work with electronics or need something handy to tighten up the hinges of your glasses. Send they give you a soft glass cleaning cloth which you can never have enough of if you wear glasses.

Sometimes I want an eyeglass strap. Usually I don't. I had one that held my glasses securely but was very hard to take on and off of the glasses. I had another that was easy to connect and disconnect from the glasses, but didn't hold them securely. This one (at least initially) is easy to connect and disconnect, but holds securely. The other included product "silicon non-slip ear clips" are something I never knew existed before seeing them here (because I wasn't looking for the right thing) and had no guess whether they would really work well before trying them. They have now saved expensive glasses that I otherwise would have had to stop using: I can only stand glasses with absurdly oversized lenses. Those are hard to find, making my only choice some cheep frames with expensive (in order to be very light weight but large) lenses. Best glasses I ever owned for a few months before the cheap hinges bent and loosened. There seems to be no practical way to buy new cheap frames and move lenses over. So I have been wearing glasses that are no longer comfortable and fall off if I look even slightly downward. These ear clips completely fix that. It no longer matters that the hinges are bent and loose. The glasses sit correctly (comfortably) again and are even better than new at staying in place when I look down. I shopped for these straps mainly as a poor solution to glasses falling off when I look down. Now I mostly don't need the straps because of the ear clips. But occasionally I want straps on my glasses for other reasons and then these are better than what I had before.

I purchased these nylon cords for myself and my husband to use us eyeglass holders. Very sturdy. Nice length. Reasonably price. Will purchase again.

On the first one, the nylon loop broke after a month and I almost lost my glasses. On the second, the nylon loosened after about 6 months and the thing was sliding back and forth on the glasses' temples until, ultimately, it slid completely off and $800 worth of glasses are gone. I threw the rest of these in the garbage where they belong. If only these things were just a waste of money, but I guess the vendor had higher ambitions. Their one and only job is to stop my glasses from falling off my head but the thing they are best at is making sure my glasses are run over by a car.

Good quality ! Does what its supposed to do !
