I am a 62 year old male.I have alittle bit of a problem with my eyes going out of focus.When I am wearing my contact lenses I notice that the distance and reading go in a out of focus.I could be wearing them for three hours and everything is ok.Then they go out of focus.After ahour or so distance will be fine and the reading will be out.When I take out my contacts and just put on a pair of reading glasses and have the same problem with reading.Any help.Thanks
