Now the claim is being made that climate change, according to Canadian research, is having an impact upon vision problems, with people in warmer regions being 50 percent more likely to suffer vision problems. The “evidence” is that stronger ultraviolet light can damage the cornea, lens and retina of the eye. That is indeed true, and it is also true that the areas of the world which are warmest, by definition have the more intense radiation from the Sun.
That does not show that global warming, so called is at work; the argument is illogical and invalid. Those regions always were a danger to people’s eyes and any alleged rise in temperature is not relevant to the existence of extra UV radiation. It is the UV which is the issue, and that is independent of temperatures. For example, there is intense UV radiation due to reflectivity in polar regions, and eye protection is needed.
Anything to promote the climate change religion.
