From the photo it looked like it was a short strap quite tight, it's much longer and this particular model has no way of making it tighter. It's not what I was looking for, but would be great for protecting sunglasses from falling overboard or drowning if they do. It was a bit tricky to put them on the glasses (as it should, the strap doesn't fall off). My son wanted them for sport (his glasses fell off every time he threw) and they weren't good enough for that.
