Utah has the lowest use of sunglasses probably because they don't drink as
much as elsewhere. Hangovers make you more sensitive to light.
Oh the horror, oh the humanity. Thank you D News for being our nanny and
telling us how to live. How did our parents and grandparents ever live long
enough to procreate? Another slow news day at the city desk?
This sounds like a scare commercial to sell sunglasses by the vision advocates
and assisting retailers. The vision industry who sell glasses and contact lens
is declining with surgical procedures eliminating the need of their services are
in a panic and looking for ways to pitch their glasses in scary medical sounding
hazardous neglect. Procedures for cataracts have synthetic materials
that block UV so what this article is seems to be an attempt by snake oil sales
pitches. The natural eye abilities work very well and the squinting mother
looking up at the interviewer with the sun at his back is far from scientific
study.Then there is the cost of sunglasses you can wear continuously
is prohibitive at $250. Since sun glasses are not a habitual or requirement to
see or shop makes them prone to be lost or left behind. Those who do spend a lot
of time outdoors are among the 70% who wear them.Then Utah has a
higher percentage not active in natrual sun light and prefer the air conditioned
"Yet, 17 percent of adults in Utah's capital city report wearing
sunglasses every time they go outside. That's 10 percent less than the
national average."Is that really the question that was asked? I
don't wear sunglasses when I go outside at night or when it's raining.
However, it's above average for the sheer amount of plastic used in
sunglasses. Especially white plastic.
This really should be in the article, as it's very important: Wearing
sunglasses without really good UV protection is much worse than not wearing
sunglasses.In natural circumstances, the spectral intensities of
ultraviolet light and visible light are well correlated. In bright light, your
iris contracts your pupil to reduce the amount of radiation reaching your
retina. Eye doctors may wish for better protection than this but it has done
pretty well for most vertebrates for hundreds of millions of years so I
wouldn't complain too much about people not wearing sunglasses.But if you wear glasses that darken the visible spectrum but do not do a good
job of blocking ultraviolet rays, your pupil expands to try to take in more
visible light, and in the process it lets in WAY more UV radiation than is
natural or healthy. You can easily ruin your vision that way.Glasses
with no tint but with UV protection would be perfectly safe. The only time when
blocking visible light via tinted glasses is really a health benefit is for
viewing sources that are too bright for your eye to adjust for- e.g. welding,
solar viewing, etc.
