    Color Distortion with Progressive Transition lens

    I am looking for any information regarding color distortion.
    Lens was a 1.6 Hoya Maestro HD Progressive with X-Active Sensity photocromic. EX3 Coating.

    Initially, he came in with seeing a neon blue shadow when looking outside at objects. They also cast a yellow outline on objects.

    Usually, if there is a distortion with color, I change the index of the lens to trivex. I did this and changed the Sensity lens to a Transition lens, thinking that this will solve the problem.

    At the second try, the blue shadowing is gone, however, he is still seeing the pencil outline of yellow.
    Rx is +2.00 -1.00 x 82 +2.25
    +1.25 - 0.25 x 85 +2.25
    Frame is full plastic, a size bigger than he was wearing currently. The only change is that he went from a lined bifocal to a progressive.

    I am not too sure where to go on this one, or even what to check or change.

    Any thoughts would be appriciated!
    Thank you!

    Probably due to prism thinning. Rare at this power and predicted (roughly 2∆) of prism. Somebody posted a few weeks ago that their lab added 4∆ of prism thinning, which is an error, and could cause symptoms. If the value is normal, you can either eliminate the prism thinning or retreat to segmented multifocals.

    Hope this helps,
