I'd like to have metadata about the materials used in the lenses, specifically info about wetting agents. My go-to lens is Acuvue Moist, which has the "Lacreon" wetting agent, aka polyvinylpyrrolidone. When my lens store stopped carrying Moist, I had a hard time figuring out which other brand would have an equivalent gradual moisture release effect, given the jungle of proprietary material names. I'm not saying I'd like to see the chemical formula for each lens (although that would be nice too), but some physical parameters beyond brand name and type of lens would be useful.
