Human Visual System: Gene identified that causes short sightedness

The BBC (center-left news, United Kingdom) reports on research at King's College London that has tentatively identified a gene that causes myopia, commonly known as short-sightedness.  For those who confuse short and long sightedness, just remember that they are what their names say - you see objects better at short distances when short-sighted and you see objects better at long distances when long-sighted.  The article is well written and has graphics to explain the condition.
