I and many others use Mike Borgelt's yellow clip on wrap around shades.
They look funny/unusual and are not easy to store but do the trick. They
also need some adjusting to some spectacle frames with scissors.
You need the wrap around to stop sun-light from the side of the face being
focussed on the *opposite* side of the cornea (clear part of the eye) and
burning it, causing a pterygium ("wing" = pterygium) that is so common in
this climate, especially blue eyed people.
Mike or his wife imports them the US and sells them snailmailorder.
