Dr Grant, I thank you for reply and I do not mean to be extra dense, but I
still do not understand what 65/62 actually means to my prescription.  How
does it affect my glasses?  What do the other numbers mean in regard to my
vision?   My eyesight was magnificent when I was younger, as is the case with
most people.  I could see and read correctly, road signs that were so far
ahead that no one else in the vehicle could begin to read until we were much
closer.  Now, I have mild macular degeneration, a brainstem tumor with
numbers 3 through 8 cranial nerves encased within the tumor.  Six weeks of
radiation is the only treatment I've received.  I can still see good when I
squint and strain to focus and move my head in different positions but I have
disturbance in both eyes.  While looking at a grid, there are waves in the
field of vision in both eyes.  I cannot seem to communicate what my vision if
like to any optician I've seen, they hear me read the bottom line on the
chart and think all is well with my vision and it's not.  Well, I find the
whole thing puzzling when it comes to understanding lens prescriptions and
would appreciate your help in learning more about all the numbers if you
wouldn't mind being of further help.  I thank you very much.
