There're section of the invisible spectrum of sunshine with a wave length below those of visible radiation. These rays are invisible and has now no relation with all the heat of your sun, thus the winter months sun has equal number of UV rays because summer sun. These rays are divided into UV-A, UV-B and UV-C. UV A and B are acknowledged to work harmful ones. The sunglasses should thus protect from both these rays. There's some evidence to trust that long lasting UV (UV-A) exposure incorporates a role in cataract formation that's the clouding of your lens. Also UV rays have already been held accountable to cause age related macular degeneration (ARMD) that is potentially blinding retinal condition resulting from retirement years. Both these conditions can result in reduced vision. Apart from the above conditions UV exposure also can spark a pterygium that's an over growth of the conjunctiva (skin with the eye). Ultra violet rays (UV-B) are able to cause skin cancers which in turn occur about the face nearby the eyes. Many of these conditions could be delayed and even prevented by good UV protection with the eyes.

Options in sunglasses

UV protection: Glasses really need an exceptional coating on there so that you can block the UV rays from passing through. Glasses may have different variety of UV protection, the recommended level may be the maximum i.e. 99 to 100% of UV protection of both UV-A and UV-B rays.

Polarized glasses: These glasses have particular lenses that reduce glare. They normally are expensive and would help in reducing glare from direct sunlight or reflected from your road, sand, water or snow. This is separate from UV protection.

Photochromatic glasses: These lenses contain the property of changing the darkness of tint according to the level of light exposure. There're dark warm and automatically become light coloured once taken indoors. This again is independent of UV protection.

Gradient glasses: These glasses are dark within the upper part and turn lighter from the lower half the lens. This is useful while driving to find out the dash board over the lighter part.

Tints: There are a variety of coloured tints available eg black, brown, grey, blue. That is a personal choice.

In addition to the classic “Web of documents” W3C is helping to build a technology stack to support a “Web of data,” the sort of data you find in databases. The ultimate goal of the Web of data is to enable computers to do more useful work and to develop systems that can support trusted interactions over the network. The term “Semantic Web” refers to W3C’s vision of the Web of linked data. Semantic Web technologies enable people to create data stores on the Web, build vocabularies, and write rules for handling data. Linked data are empowered by technologies such as [[RDF]], [[SPARQL]], [[OWL]], and [[SKOS]].
Myths

There are plenty of misconceptions regarding sunglasses. Doctors at try to clarify a number of.The everyday myths while getting a couple sunglasses is the fact a darker or even more expensive set of two glasses will offer good protection. Darkness has nothing related UV protection, plus its more bad for wear dark sunglasses without UV protection these days to put on sunglasses in any respect. This is due to behind shades the length of the pupil becomes larger and without UV coating allowing more harmful Ultra violet rays to go into a person's eye which could have otherwise been partially blocked because of a smaller pupil without the glasses. Also the majority believe sunglasses are meant simply for our summer months, that's untrue because the UV rays are almost equally harmful many of the all year round.

Recommendations

You can find many brands & many stuff as in sunglasses, though the recommended by  are definitely the following.

Sunglasses must have a 99 to 100% protection from UV rays (both UV-A and UV-B). Most branded sunglasses has these details with all the product. Some brands have UV 400 designed in them this means, it blocks [http://vienne.co/gio-xach/ gio xach] approximately 400 nm of light consisting of the Ultra violet rays.

In the event that you have to acquire prescription sunglasses from your opticians then the quantity of UV protection on any lens is usually measured by way of machine that many good opticians possess.

Since UV damage is lasting, starting early is recommended. Children should wear sunglasses whilst outdoors in sunlight regularly. Very few brands make sunglasses for the children and which is usually difficult to get children to keep glasses on, a rimmed hat or possibly a cap can usually provide substantial protection.

In addition to the classic “Web of documents” W3C is helping to build a technology stack to support a “Web of data,” the sort of data you find in databases. The ultimate goal of the Web of data is to enable computers to do more useful work and to develop systems that can support trusted interactions over the network. The term “Semantic Web” refers to W3C’s vision of the Web of linked data. Semantic Web technologies enable people to create data stores on the Web, build vocabularies, and write rules for handling data. Linked data are empowered by technologies such as RDF, SPARQL, OWL, and SKOS.

The goal of this wiki is to provide a “first stop” for more information on Semantic Web technologies, in particular on Semantic Web Standards published by the W3C. It does not aim to give a complete set on information on Semantic Web related events, conferences, ontologies or community efforts. There are already a number of sites maintained by the community that users can refer to (see some below).

Other sites of interest

This is certainly not the only wiki or general information site on Semantic Web. Here are some additional ones that might be of interest:

  1. Semanticweb.org contains references to events, news, personal pages on the community.
  2. the Semantic web “dogfood” site contains the on-line proceedings of a number of Semantic Web related conferences
  3. The OWLED Wiki is for supporting the OWLED Workshop series and task forces
  4. The Ontology Design Pattern Wiki is a Semantic Web portal dedicated to ontology design patterns (ODPs).
  5. Semantic Overflow, a community based Semantic Web Question-and-Answers site
  6. Semantic Web Meetups give a list of all the local "meetups" in the Semantic Web area around the globe.
