I tuned into this thread a bit late, but perhaps I can be of some help. As
an optometrist, I can at least shed some light on the problem with the
lens--which appears to have broken due to impact, if I'm extrapolating
correctly--or at least with why it didn't protect the eye. Please feel free
As to seeking legal help, that should be a last resort effort. As soon as
you retain an attorney, any cooperation between the doctor and the patient
evaporates, by instruction from the doctor's lawyer. Most problems can be
worked out without dragging the issue into a legal environment.
Contrary to popular belief, safety glasses really provide very little
protection against impacts of significant velocity and/or mass. At best
they will keep flying particles and tiny objects out of the wearer's eyes,
but are limited in effect with respect to heavy objects flying at
significant velocities. Crown glass safety lenses are really no better than
CR-39 hard resin (plastic) lenses made for non-safety glasses, and most
likely worse. The best lenses are polycarbonate, but their ability to
resist significant impact is limited by the ability of the frame to hold the
lens in place without releasing the lens or collapsing under the impact.
Polycarbonate generally won't break or shatter. And you are correct w/r/t
goggles--they offer superior eye protection. So do polycarbonate face
Well, it was a few years ago so the lawyer is out. I had been
clearing the chunks at the beginning. I was trimming a bunch of
poplar 2x2's and got tired of moving the scraps off the table.
After all they were just sitting there. Then one jiggled just far
enough for the rear tooth of the blade to toss it at me. I tend
to have a little retroactive amnesia whenever something like this
happens so the next thing I remember was holding one hand over the
damaged eye and looking for the glasses with the other eye. Found
the glasses, picked up the lens pieces and went for a ride.
As I read in a library table saw book, use compressed air to blow those
babies off the back of the saw. It's fast & easy.
This is the primary reason I find myself looking at the HF compressors each
Sunday on my way home after church. ;-)
What material were the lenses, Joe?
As I mentioned earlier, polycarbonate is the only true safety lens. For
future reference, insist on polycarb for any pair of glasses you wish to use
with activities that have the potential for flying objects. And no rimless
or semi-rimless frames, either. A good, solid plastic or metal eyewire
surrounding the lens is an absolute necessity for holding the lens in place.
Believe it or not the way we determine glass vs. plastic is to tap them
gently against a tooth. If the resulting sound is a bright "click" they're
glass. If the sound is a dull "clack" they're plastic. Obviously if
they're in pieces they weren't polycarb. I've seen polycarb lenses that
have been placed in a vise and shot with a .22 caliber round at close range.
The bullet distorted the lens by about an inch, but failed to penetrate. No
Just thought I'd mention that it is umwise to feed short lengths of wood
(prunings from cutting bowl blanks that had a very rough de-horning prior
to planing) into the planer if they have a deep dish in the top side. Not
even if they have absolutely gorgeous grain that it would be criminal to
They start to feed in, then halt because they are past the first feed roller
but not yet to the second.
Then they make a large BANG! sound when you push them into the blades with a
push stick. If you keep trying, it is possible for them to get small enough
to fly out backwards at speeds approaching the speed of light ... well, I
never saw it move, but my knuckle recorded the fact.
