BIRCH's Black Sports Safety Glasses Sunglasses Holder Eyeglasses Neck Cord String Retainer Strap

I got these for my safety glasses at work which kept falling off my face every time I leaned forward. These comfortably prevent that from happening.

I used it for my sunglasses. Easy to slide on, to adjust, stays in and I don't have to worry about losing my sunglasses.

I need a strong, functioning, good glass holder for my work, and this product works well. However, omg, it smells so bad. I thought some homeless people invaded my office.In order to use, I had to wash this product many many times with all kinda different things.

Very strong hold.

Nice product. But it did not fit my 1/4 inch sunglass stem as indicated in the description. I'm using it on a pair of reading glasses and looking for a holder that can handle a larger stem. I see where they suggest using a hairdryer to make them potentially fit by heating the ends--but it seems way too small to even try. Easier to find another product.

Paired with magnifying glasses and a clip on light, completely replaces my old Orascoptic glasses at a fraction of the cost

In general, these seemed to work well for what I wanted and I would have rated them higher, but about two weeks after I got mine, one side came unglued and allowed my glasses to fall off. Luckily - this time - the glasses where not scratched or lost, which would have put me out several hundred bucks for replacement prescription glasses. While some quality superglue seems to be working as a fix, I will now always have the nagging feeling the other side will fail unexpectedly in the future. I may even place a small band of black wet-weather (melt-able glue) heat-shrink tubing over the connections where the neck cord meets the eyeglass tubings to placate my paranoia...Update: Unfortunately, about a week later the other side came unglued (and I re-glued it). About a month after that, one side of the plastic tubing ruptured and I just threw these away. These probably caused my glasses to fall more unexpectedly than if I had not had them on in the first place. I have since bought a pair of the "Peeper Keeper" eyeglass neck holders and so far they seem to be a better product.

Good product, great price. Holds up to serious abuse.
