Playing havoc

Only now do I understand why the captcha thing offers an audio version. Prove you are not robot Type in the letters you see. But….. I cant see them. Also eye patch and swollen eye playing havoc with my biometrics facial and iris recognition. Today, bit of a breakthrough, My eye is more open, less gummy and the spirit level has dropped t about 3/4 position and yes, my normal myopic eyesight is the same as it was, above the spirit level/gas bubble and the black, half moon shadow has gone from inside corner of left eye. There is still however a juddering and flickering bottom left corner of my eye .
