I thought it would be funny to share funny stories that have happened either to you or someone you work with. I will start. When we take segs on sunglasses we use a pen light to be able to see where to measure. Unfortunately its not the only light that we keep at our desk, we also keep a high power UV light to demonstrate photochromics. I happen to glance up as our new girl went to take the seg and noticed a purple light on the patients face....to make matters a little worse (also a little funnier) the patient is monocular and she was measuring on his good eye. I quickly and gently corrected her but it's still a fun story to tell.
