How much lighter in weight is Thin and Dark than PGX and how much heavier than a standard plastic lens?

Thin and Dark lenses can be up to 30% lighter than PGX; they are 5% liter in density than PGX and can be 25% thinner (1.5mm CT vs. 2.0mm CT). The difference in weight between single Thin and Dark lens and standard plastic lens with a 2.00d Rx and a 50-eye size is equal to about the weight of a dime.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
