I have a question on how other people measure seg heights on extremely tall people. Example is I had a patient last week, who is 6'9. I am 5'4 and he towers over me..... and most other people and noticed when he looks through his glasses when standing up he would be looking through the intermediate part of his progressive. So I measure him sitting and standing... and did half of the difference. I am hoping this will work but that was my best guess as how to measure him seeing is how I have not run into this problem yet.

Thank you for your input!!
