Hi john,ive sort of asked this before im going try to explain it to you again.i have very advanced keratoconus and if i look at writing on the tv it is all muddled up,,,,but i have a ghosting image of my thumb if i look at it,if i put the thumb below my eye and look at the tv through the ghosting part of my thumb the writing on the tv goes completley clear and the ghosting goes?this happens with or without the contact lense in?im worried that this could be a brain thing?slightly worried thankyou
