Peter Your talk of pterygium and blue eyed people got me worried because I've got blue eyes (with no others for 2 generations up the family tree), and so have my 2 kids (even though my wife has brown eyes which should be dominant, I guess she carries a recessive blue eye gene).
For others wondering what the fuss is about, a quick search for pterygium in Google revealed many sites, including http://www.stlukeseye.com/Conditions/Pterygium.asp and http://www.revoptom.com/handbook/sect2i.htm Thankfully I don't seem to have this, but I will certainly keep an eye out (no pun intended) in case it ever becomes a problem. With regard to the polarised magnetic clip-ons, I should point out that my frames were specifically designed to accomodate them - they are sold as a matching set, and are not something you simply tack on to an existing pair of glasses.
