I've read all the glasses related threads before, so I had some small idea of what could be done. At my eye doc appointment a couple years ago, I tried to talk to my guy about it, and he blew me off, not wanting to get into it. At least that was the feeling I got.
Two months ago, I decided to try someone new, that my optical insurance would cover. I tried to gently lay the groundwork with the technicians who were doing all the test work. Imagine my surprise when the doc came in. She looked at her charts and said "you have a problem, you shoot pool!". When I stopped chuckling, we had a great conversation about what I felt was happening with my current bifocals and how it affected my play. She understood completely, and said "no problem...I'll just write a prescription to move the blah blah blah blah" and away I went.
Being on a budget, I checked to see what EyeMart had and what it would be after insurance. I found a pair of frames that were higher on my face, and ordered them. I have been quite pleased with the results.
They may very well be less than I would get from the folks mentioned here, but I am satisfied. When I forget to change to my shooting glasses, I immediately squint to see down table. Not so with these, its much easier on my eyes, especially over a long night. It's not like its night and day different, but it is significantly clearer and sharper. Any little bit helps, right?
I recommend anyone who wears glasses investigate shooting glasses, either with the folks mentioned in this thread, or with your own doc. You will be glad you did.
