Plastic Eyeglasses The Color Of My Plastic Eyeglasses?

The color of my plastic eyeglasses? - plastic eyeglasses

if I have a pair of thick glasses in lime green for a little over a year, and the plastic frame is in danger and today is a mint-green, not even close to the original shade!

I wonder if there is no way to paint "or" color "part back to its original color, or at least a similar color, and if so, what kind of paint / use color and how I am.

Also for the future, it is possible to prevent the ink in the plastic bleaching, before it starts?

Thanks in advance!
