ok can anyone shead light on the Gradal RD lens. in my office we rarely use it but it is called upon. how is it measured? is it even good? is there any other no line type lens that is better to use? i have very little knowledge on this lens or even how to dispense it and what verbage to use with patients. i feel akward when the dr asks me to put a pt in it because i always have to wing it conversation wise. Please help fellow optiboarders!!!!!!!!!!!!!!!!!!!!!
many thanks
