I was wondering if anyone knows of any reason why labs leave the PAL markings on the lenses when they are returned to the optician? Also, is there any purpose to leave them on after checking seg ht, PD and Rx? I find it very time consuming to clean off when making a delivery. Especially if the markings extend beyond the eyewire. You have to use a Q-tip to get at it and it still is difficult. I do understand that you can check for fit on the patient. This can be done also by checking near and distance vision and noting if any head posture change is necessary. If their vision is quite poor, we could remark the lenses and check then. If the glasses are checked/passed at return from the lab, there should be very few instances where this would occur. Give me your input, please...................Mullo
