Eyeglasses for night a blur?

Question

I've never worn eyeglasses for night vision until now. the first time I wore them at night while driving, any light I looked at projects a kind of prism/star shape. My glasses came with an antiglare coating. Has anyone ever had this problem? My Opt didn't know why I have this problem. The prism is only there when I wear them not when I don't. thanks

Answer 1

I had a patient with that same problem a couple of months ago.

My lab said it was a defect in the hydrophobic coating that was making the AR do that.

They remade the lenses with a new coating and the problem was gone.

Answer 2

sometimes this happens due to smears and smudges on your lenses.  With the AR coating, it is very bothersome.  Make sure you clean your lenses thoroughly before you go for a drive at night.
