Answer to Question 1

The polycarbonate is tougher, stronger, and more scratch resistant.

Answer to Question 2

The major problem with UHMWPE is the difficulty in melting and processing the material. By adding a low molecular weight polyethylene, the material will melt and lubricate the higher molecular weight mass, thus allowing the material to be processed even though it is not fully melted.

This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition.
