I love my varifocals but needed to learn to use them. I suggest you spend today practising and really thinking about which part of your lens you are using. Looking out of the window - head straight, eyes using top part of lens; looking at the carpet, head bent, eyes using top part of lens; looking at print on a table, head slightly up, eyes down using lower part of lens; looking a small print on a wall, head tilted back, looking down your nose and using lower part of lens; Stairs, paths etc, head bent down, eyes using top part of lens.
It will become second nature to you and you will soon be noticing others who use varifocals - those of us reading timetables on the station wall with heads bent right back and looking really snooty!
Don't give up yet - good luck!
