VSP and EyeMed are two different companies. The biggest difference between the two is where you can use the plans. With VSP, you can get eye exams and glasses or contacts at certain eye doctors, Walmart, Costco, Sam's Club or Visionworks. With EyeMed, you can go to in-network eye doctors, Target Optical or LensCrafters. You might have more options with either plan depending on where you live.
