johncocker Posted October 30, 2011 Share Posted October 30, 2011 . I've just been watching a doco on lincoln hall the climber who survived a night exposed on Everest at a height of 8,700 metres, which is known as the "death zone". he had pulmonary oedema, fluid on the lungs, as well as frostbitten fingers, one frostbitten toe, a chest infection and cerebral oedema, or fluid on the brain,......and one thing that puzzled the experts was his eye color changed from blue to brown:huh: Link to comment Share on other sites More sharing options...

HeadingNorth Posted October 30, 2011 Share Posted October 30, 2011 Eyes appearing to be blue, green, or light brown depends on the amount of Rayleigh scattering going on inside the eye (for an explanation of which, look it up online since I'm not entirely sure I understand the principles involved.) If exposure to extreme conditions has caused a minor change in the chemistry, or physical shape, of his eyes than it's quite possible that the colour will have changed as a result. I've heard of this happening before for other reasons. If anyone wants to change their eye colour, then coloured contact lenses are probably a safer option than spending a night on the summit of Everest.

Amaranthus Posted October 30, 2011 Share Posted October 30, 2011 Someone told me that their daughter's eyes changed from brown to green a few years after moving from the UK to Spain. Link to comment Share on other sites More sharing options...
helhol Posted October 30, 2011 Share Posted October 30, 2011 you can get coloured contact lenses but if you have blue eyes and use yellow cat like ones beware, my son used some and he just ended up with green looking eyes lol, not what he wanted but looked good Link to comment Share on other sites More sharing options...
Flowersfade Posted October 31, 2011 Share Posted October 31, 2011 To answer the question. Yes it is possible for an eye colour to change naturally. My own eyes changed colour at around six. Also there is a surgery which can be done however this is not available in the UK as far as i'm aware. It involves a silicone lens being inserted into the eye. It is not without risks.
