   Re: Acceptable deviation from axis value

   I hope someone can help me and direct me. I am legally blind with limited   
   Vision in only my left  eye. I am trying to replace a broken pair of my   
   glasses that I use for my distance vision. I recently went to an optometrist,   
   had an exam and was given a    
   pair of glasses, which I could not see well out of at all. The vision with my   
   old broken was much better. I went back to the optometrist, and he said the   
   only thing that he thought it might be due to was the astigmatism part of the   
   script. He didn't    
   really seem too sure so we both decided that since my old script had worked   
   well for me we would just redo the new glasses the same as my old script. I   
   did not have the written prescription so they took the script directly from my   
   old glasses. The only    
   difference between my older glasses and the new ones being made where that my   
   old glasses were made from polycarbonate without an anti-glare coating and the   
   new ones were going to be a high index glass with anti-glare coating. They   
   said they can only    
   redo the glasses one time and that if they didn't work out they would not be   
   responsible. They assured me that the high index lens would give me even   
   clearer Vision then the polycarbonate lens and the anti-glare coating would   
   not affect the clarity or    
   the vision. I went to pick up the new glasses today and once again the script   
   did not seem correct! I can't focus as well with the new ones as my old ones   
   even though they insist that the script is the same. I asked if it could be   
   the way the lens was    
   placed in the frame and they said it was placed accurately and the same as my   
   old ones. They have refused to redo the lenses and will not give me my money   
   back which I paid out of pocket without any insurance coverage. I immediately   
   went down to another    
   optometrist office and ask them to compare the script of my new glasses with   
   my old ones. The OD on both prescriptions was the same,-300. I have no central   
   vision in that right eye so it is mainly used as a balancing lens. The OS in   
   my older glasses,    
   which work for me, was -4.25-75-110. The other optician said that my OS script   
   in my new glasses is-400-75x90. I do not know what any of these numbers mean.   
   I asked them why the two numbers at the end were so different and how that   
   would affect my vision.   
    She told me that those numbers were they axis measurements for the   
   astigmatism. With that mean that they are 20 degrees off? From reading the   
   previous post I would think that 20° would make a big difference in the way I   
   am focusing. I don't know if the    
   measurements of-425 and-400 would make a big difference. I am trying to find   
   out why I am having a problem getting a simple pair of single Vision distance   
   glasses. These glasses were not sent out to a lab. They ordered the lens and   
   put them in the frames    
   themselves. Could it be possible they are not situated right in the frames or   
   would the difference in the prescription be the problem? Since they are   
   washing their hands of the problem is my only recourse to purchase another   
   pair and throw away this    
   money that I paid for these glasses? I am a disabled Widow and cannot afford   
   another pair of glasses. Is there a society that over looks the optometrists   
   that would assist me and to getting the correct pair of lenses from this   
   optometrist? So now I am    
   back to wearing my scratched glasses which have the arms held together with   
   paper clips! All I wanted was the same exact lenses in the new frames! I am   
   trying to understand what is causing the problem in the focusing and need   
   advice on what I can do to    
   rectify the situation. Please help!
