My eyes are not bad but that may mean different things to different folks so I’ll give a concrete example.
Yesterday I was looking in Cunliffe at two entries of [size=150]οῖος[/size]. I cannot see if the breathing mark under the circumflex is smooth or rough.
I can read the rest of the print well enough but a breathing and a circumflex over the same letter is hard to tell in Pharr’s book and impossible to tell in Cunliffe.
Thanks for the information you have given.
