Re: Being born in the summer increases your chance of being short sighted

Forming a large multi-center Israeli team, the scientists took data on
Israeli youth aged 16-23 and retroactively correlated the incidence of
myopia (short-sightedness) with their month of birth. The results were
astonishing. Babies born in June and July had a 24% greater chance of
becoming severely myopic than those born in December and January -
the group with the least number of severely myopic individuals. The
investigators say that this evidence is likely applicable to babies
born anywhere in the world.

If that is actually what they mean to say, then it isn't summer that does it.

As far as I can see they haven't any data from the Southern Hemisphere so they have no idea whether it's summer that does it.
