One of our accounts is asking for a water-tight liner or seal inside the eyewire of Shark swim goggles they order. Anything we try won't stay in. They say other labs can provide this. I say if the lens is sized properly and the strap is adjusted on the head properly, there is NO problem with the seal. MY hunch is they are being fed a bunch of baloney and being charged from the other lab for a seal that is not there. I need a good lab tech to weigh in on this.?????
