I'm hoping some of my fellow opticians out there have seen this in a progressive lens!
I have a patient who was prescribed with a plano power progressive lens in his left eye. His right eye has just a little plus power in it, but that eye is not the issue as he doesnt notice the following in this eye. His vision is great and he likes how the progressive works. HOWEVER, he tried to explain to me that in the distance portion of his left eye, the plano power, he notices certain lights are doubled. He explained that, especially at night with an oncoming headlight, he would see the same point of light doubled. Again, it's only in that left eye...there is no issue with prism imbalance or anything to that nature. I could not see what he was saying and I even cut him another lens just to satisfy.
The second lens...same thing! Frustrated he stepped outside the store for a moment and then returned. He brought me outside the store and told me to look through just the left lens in the distance portion and pointed to a halogen type light down the walkway. I had to move the lens in and out just a little bit, but sure enough I could now see what he meant! It was like the same light had a second image displaced just above it and almost forming a pyramid shape distortion of that light.
I even tried a different design progressive but it is doing the very same thing! I am wondering if A/R will take that ghost type image of light away, but I don't understand why it is doing that on just the plano lens and not on the lens with a little bit of power in it.
Has anyone else seen this or can provide me with a little insight as to what is causing this? If you need further info I will provide. I want to be able to offer this patient an explanation! Thanks for your help!
