For those who have everything: The EnChroma Cx-D or Cx-PT sunglasses

If you’re one of the more than 10 million Americans who are color blind, the EnChroma Cx-D or Cx-PT sunglasses could change your life. Creator Don McPherson, who holds a Ph.D. in glass science, stumbled upon the concept when a color-blind friend borrowed laser-operator safety goggles one day to play ultimate Frisbee. McPherson discovered that the goggles allowed his friend to distinguish colors because the lenses isolated color wavelengths, keeping reds and greens from blurring into brown. The EnChroma lens “applies the same idea” but refines it, and comes in stylish aviator or Buddy Holly–style frames.
