Hi every body
i think now its time think about the solution of old stock of cr-39 finnsih or semi-finnish lenses,
i have done so many expairmetns tinting, sun bleaching , but after hard coating or hmc the get more yellow. :(
we have discussed alots topics of diffrent issues and we got the best answers but still unfortunatly there is no comfortable solution for cr yellow lenses yet.
Here in this forum we have alots father of ophthalmic lenses. I request to sort out the best solution for it...
Thank you
