This is so cool! Dr. Perry Rosenthal has created a lens to help people see.
from GMA: For more than 30 years, it has been Rosenthal's mission to do what seemed like the impossible — to help the blind see. He's doing it with the Boston scleral lens, which sits on the surface of the cornea. "Even though the corneas can be very distorted and irregular, when light comes in through the lens, it only sees the smooth surface, the irregular surface is hidden by the fluid," explains Rosenthal.

Nearly 400 people now wear these contacts, which cost $5,500 for a pair.
