Thanks
Thank you everybody for your helpful suggestions.
I shall certainly try a spot of bright paint on the sights and see if that helps.
Also I remembered that when I go to have my eyes checked they fit a pinhole in front of the eye and suddenly I can read all the letters on the chart!
So some room for experimentation.
I may get a Crosman 2240 to play with and try the red dot idea.
Its either that or stick to my rifle..
Regards
Andrew
