This is a difficult issue. I've worked with blind skiers in California and Utah. The categories for "VI" visually impaired are simply high partial vision, low partial and total loss (B3 thru B1). So competitors with extremely restricted foveal vision (central point of focus) are there with others with complete field of vision and very low contrast. The B1's compete with blackout materials in their goggles to ensure that they really are B1's. There's the usual issues that certain national adaptive sports federations are incredibly well funded, like Spain's, which is/was fed by the national lottery. http://en.wikipedia.org/wiki/Paralympic_alpine_skiing http://en.wikipedia.org/wiki/Paralympic_alpine_skiing
