Ultraviolet (UV) light is an electromagnetic radiation with a wavelength from 400 nm (750 THz) to 10 nm (30 PHz), shorter than that of visible light but longer than X-rays. Though usually invisible, under some conditions children and young adults can see ultraviolet down to wavelengths of about 310 nm, and people with aphakia (missing lens) can also see some UV wavelengths. Near-UV is visible to some insects and birds.
UV radiation is present in sunlight, and also produced by electric arcs and specialized lights such as mercury-vapor lamps, tanning lamps, and black lights. Although lacking the energy to ionize atoms, long-wavelength ultraviolet radiation can cause chemical reactions, and causes many substances to glow or fluoresce. Consequently, biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules.
Suntan, freckling and sunburn are familiar effects of over-exposure, along with higher risk of skin cancer. Living things on dry land would be severely damaged by ultraviolet radiation from the sun if most of it were not filtered out by the Earth's atmosphere, particularly the ozone layer. More-energetic, shorter-wavelength "extreme" UV below 121 nm ionizes air so strongly that it is absorbed before it reaches the ground. Ultraviolet is also responsible for the formation of bone-strengthening vitamin D in most land vertebrates, including humans. The UV spectrum thus has effects both beneficial and harmful to human health.

Consumer correspondent Susan Koeppen tested sunglasses at all price points to find out if they really offer UV protection.
We showed people what they looked like in ultraviolet, & wondered aloud if they wanted to put on some damn sunscreen already. https://twitter.com/thomasleveritt Music: 'Summer in the City - Starcadian remix' by Freedom Fry http://freedomfry.bandcamp.com/track/summer-in-the-city-starcadian-remix They are awesome.

UV protection spectacles are special glasses that will darken upon exposure to UV, very expensive and used mainly as prescription glasses. Safety glasses are unbreakable polycarbonate that protects users 100% from UV.
Americans on average spend more than 100 minutes in their cars each day. There are standards in place for UV protection on windshields, but it may not be enough.

In case you are wondering how to check the UV protection, we have 2 methods for you: 1. Get a UV flashlight. If you go in a dark room and beam the light on money paper you can see the lines and symbols only detected by UV light that government officials use to differentiate counterfeit money. Now put your glasses on and if you can still see the symbols your glasses are not 100% UV protected. 2. Bring your sunglasses to your local optometrist. They will usually have a device that can tell the prescription of any lenses and this device also has a spectrometer. The device measures the transmittance of UV light.

Commercial parody. You my have seen it, but its so funny a had to post it.
i was looking for a way to test put if the glasses i got claiming to be 100% UV protection actually ware doing anything at all so my options ware taking them to a shop where they can do this test, buy a UV meter for 500 bucks or find a walk around which i think i did. i got the bulb from amazon:http://www.amazon.com/Sunlite-SL20-BLB-Spiral-Blacklight/dp/B002P4TYVK/ref=sr_1_1?ie=UTF8&qid;=1442302282&sr;=8-1&keywords;=uv+light+bulb
This informative and educational video offers viewers practical and useful tips on eyes protection from harmful UV rays. Prolonged exposure to harmful UV rays can cause cataracts and macular degeneration. Even children should be protected too. Learn what to look out for when buying sunglasses such as darkness and colour of the tint, and the types of lenses.
I heard of a way to maybe allow me to test if all these UV PROTECTION claims you see on most sunglasses were true. This video shows that method. GOOD SUNGLASSES DO NOT HAVE TO COST A LOT OF MONEY. I just bought some great UV blocking sunglasses for $6.00 online and I like them. I made this video last week and I have been hesitant to post it because I am no eye doctor or expert... but I really liked learning about a way I myself can check the sunglasses I wear and it was so cool and such a good idea that I thought I should make a video showing it and share it... but...

The Shield Project - künstliches (Nano) UV-Schutzschild Die verstorbene Rosalie Bertell erwähnte enormen Ozonverlust in ihrem Buch "Kriegswaffe Planet Erde". Interessanter Weise haben einige Länder und Institute (ua. Schweiz und Deutschland) bereits Mitte der 90er Jahre Forschungen betrieben, welchen Schaden erhöhte UV-Werte in der Nahrungsmittelindustrie & Landwirtschaft anrichten und wie man Vorsorge treffen könne. Grund war für diese Forschungen, das WISSEN darum, dass die Ozonschicht unweigerlich verdünnt ist & weiterhin abnehmen wird und die UV-Strahlung ansteigen wird! Wie gesagt - sie wussten davon und darum! Was wusstet ihr darüber - aus den Medien, der Politik, der Wissenschaft oder Bundesbehörden? Ich denke mal rein zufällig NICHTS... http://solomio.freehostyou.com/index.html#...

Dr. Joseph Sobanko dispels myths and discusses the facts about UV light, sun protection and skin cancer at the CANPrevent Skin Cancer 2012 Conference. A skin cancer patient talks about effective strategies for protecting his skin from further sun damage.
Come say hi on Instagram https://instagram.com/lisaeldridgemakeup/ This film is full of information about the latest rules, regulations and the ingredients to know when it comes to sunscreen. I've spoken to many dermatologists and scientists in the UK and USA and have included products recommended by them, as well as some personal favourites that I use on myself and my celebrity clients. Keeping your skin protected in the sun is one of the easiest ways you can keep it looking younger for longer, and with so many great textures and formulas available now for every skin type, there really is no excuse not to wear SPF everyday ;) I hope the film is helpful for everyone who asked for it.x On my lips is Lancôme's Shine Lover in 218 : http://lisae.me.uk/26801-27000 and Charlotte Tilbury Lip C...
Делюсь опытом использования двух моделей солнцезащитных спортивных очков от ROCKBROS. Очки с фотохромными линзами и очки с пятью сменными линзами. Обе модели в легких удобных пластиковых оправах, с линзами из поликарбоната и 100% защитой от ультрафиолетового излучения. В видео расскажу о сильных и слабых сторонах обеих моделей. Использую эти очки для ежедневного ношения в городе, на стрельбище, на рыбалке, в водных и пеших походах, при катании на велосипеде и пр. и пр. 00:12 Спортивные солнцезащитные очки Rockbros Поляризационные, фотохроматические ("хамелеоны") Защита от ультрафиолета: UV400 (100%) Материал линз: Поликарбонат Коэффициент пропускания: 80%-18% 80% света при низком УФ, 18% света при высокм УФ) Вес: 26 г Ссылка на AliExpress: http://ali.ski/RlPwt 07:29 Спортивные солнцезащ...
