The following is a long discovery process that I had to go thru with wearing safety glasses.


Symptoms: immediate eye strain, difficulty focusing when putting on safety glasses. Headache after prolonged (a day) wear of safety glasses.


Symptoms started when I was in high school. During the brief period that I had to put on my safety glasses for labs, I found out my eyes were giving me problems. It seemed at the time like my eyes were trying to focus on the glasses themselves (which are very close to the eyes of course) instead of focusing on objects.


Fast forward some years, and I had to wear safety glasses most of the time at work. Very big problems started appearing no matter what I have tried. My eyes would get eyestrain, I would have difficulty focusing my eyes while wearing safety glasses, and I would get a bad headache at the end of the day.


Even after the glasses were taken off, my eyes would straing themselves driving back home. At home, focusing at objects became a problem, with severe eye strain required to focus my eyes. Severe eyestrain was required to focus on the computer screen at home, while more distant objects were easier.


And all this time, everyone treated me like they did not know what I was describing. Needless to say, they had no idea what I was going thru.


What I have found:

1) Many more people that you, I, opticians, and businesses realize cannot wear safety glasses.

2) The problem IS NOT due to astigmatism. On the weekend (when my eyes rested a bit after being raped during workweek), computerized eye exam showed 20/20 vision, very tiny astigmatism (no need to even correct).

3) Everyone freely admits that polycarbonate safety glasses have severe distortion due to being made of plastic and injection molded.

4) The problem is not strictly due to material (more on this later).


Things that I have tried:

1) All safety glasses designs that I could get my hands on. Some were a little better in that the eyestrain would come on later. But none were confortable after short-term wearing.

2) Safety glasses that were described to be "low-distortion". I have even tried safety glasses made from real glass and advertised to have zero distortion. The results - I could not even put them on.

3) Other designs such as safety goggles. And I was laughed at. People thought I was wearing the very ugly goggles because I had nothing better to do. As you can guess, I tried goggles because they have a relatively thin and flat sheet of plastic in front. Did not work.

4) Safety glasses described as "optically correct". I have found they are nothing to support the claim. Not any better.


What do I see:



  • $200 lenses, $100 frames
  • eyes in center of curve
  • DATE, PRINT, SIGN



goggles to todo, license:

  • must be diff width
  • complete width of vision
  • all notes to one file and inventors notebook



problems with common safety glasses:

  • peripheral vision
  • irregularities
  • scratches
  • smudges
  • must be trivex or other, not polycarbonate
  • Trivex glasses with optically correct lenses


all solved w glass glasses in kit w holder and cleaner



market research – people are familiar, but rep said nothing helps because noone caters to the market, she said all goggles will have distortion.



Companies that sell volume safety glasses:

  • Northern Safety & Industrial
  • New Pig
  • Lab Safety




like other medical problems that are not immediately noticeable, problems with curved plastic glasses and safety glasses must be widespread, but people do not notice it immediately. Even larger term is vision loss due to prescription lenses. Crit business:

  • flat zero distortion unscratcheable glasses
  • non-acrylic non-prescription retail glasses
  • try-out safety and prescription materials frames +lenses (won's problem, and probably many others')
  • regional courses on vision improvement from those bh / c2c / HRNN guys


glasses:

  • no frameless bc no holes
  • my magnification test
  • tri not more scratch resistant
  • still advantage for my startup: unscratcheable, super wide fov, sideshields
  • market research: 0.5% cannot handle poly at all, problems like me



factors:

  • distortion
  • spherical
  • scratches
  • fov
  • astigmatism



q acrylic readers do they have distortion like polycarbonate?


Pressed acrylics


no generic frame+lens lk readers



aspheric


my eyes are 66mm apart


doc to call for frames, verify coverage, verify trivex safety glasses


$300 frame +lens




doc safety glasses:


  • not alone
  • other types beyond polycarbonate are available – trivex, safety glass if thick enough
  • national locations
  • symptoms
  • scratches, smudges, peripheral
  • what to say to opticians to find out if they understand
  • exam not after workday
  • clean and no scratches
  • keywords
  • my story
