“This "optical clip" was the only way to add a corrective prescription to the frame as the lenses themselves can't be made with correction. They work ok, although their thickness is such that when I place the glasses where they are comfortable and my eye sight goes through the center of the optical clip, my eye lashes touch the clip which is very distracting.
All in all, they are acceptable but in the future, I will probably look for a frame/lens combo that can have the lens itself have the corrective prescription.”
