This forces the eye to focus constantly and as a result, the eye gets tired quickly. Blue light can cause different eye diseases. One of the diseases is „Dry eye syndrome“. Dry eye syndrome is a collection of symptoms which are caused by a lack of or low quality of the tear fluid. This can not be completely cured but it can be prevented by resting the eyes after every half an hour when using smart devices. Another disease which can be caused by the blue light radiation is Macular Degeneration Disease. Macula is located in retina and the image that is focused on the retina is the sharpest in macula. This is the reason why macula can not be damaged at all to have a correct visual acuity. Blue light damages the light-sensitive cells in retina. Macular degeneration disease can lead to permanent loss of eyesight. Both of these diseases can not be cured but it is possible to prevent them. The best prevention would be to avoid the use of smart devices
Eye Eye is an organ in both humans and other animals which allows to see. Blue light causes damage Smart devices radiate blue light Blue light has damaging effect on the eye because it refracts in front of the retina This forces the eye to focus constantly so the eye gets tired quickly. „Dry eye syndrome“ Dry eye syndrome is a collection of symptoms which are caused by a lack of or low quality of the tear fluid Lack of eye blinking Macular Degeneration Disease Macula can not be damaged at all to have a correct visual acuity Blue light damages the light-sensitive cells in retina Macular degeneration disease can lead to permanent loss of eyesight.

fire for religious purposes. They perform a ceremony of purifying the crops when they begin to bear. Part of this ceremony involves lighting the holy fire and carrying it to all the regions. · People look upon it as a "purifying flame," and eagerly wait to catch it with twigs, in order to take it to their homes. It symbolizes the process of death and resurrection, and the concept of renewal over destruction and degeneration. Arts and crafts · Diverse cultures and traditions in Kenya imply very rich source of art work. Every community is known for its special kind of art. The most popular items include: Maasai blankets, Kisii soap stone carvings, wooden carvings, Maasai beads, tribal masks, Kangas, kikoi, sisal baskets among others. · Kenyan animal hide drums will always remind you of African rhythm.

geenidefekt kahjustab silma fotoretseptoreid. Tänapäeval on selge, et hoolimata silmapõhja uurides leitavatest üsna sarnastest muutustest on tegemist eri haiguste rühmaga." Nüüdisajal on kindlaks tehtud, et haigust põhjustab geen ligi viiekümnel erineval koeratõul, seal hulgas ka segaverelistel koertel. PRA varieerub tõugude vahel vaid niipalju, et tal on erinevad haiguse avaldumise ajad. Tavaliselt avaldub enamikel koeratõugudel PRA vorm prcd PRA (Progressive rod-cone degeneration), mis tähendab seda, et kepp- ja käbirakud arenevad normaalselt ning hakkavad taandarenema hilises faasis ja koerad jäävad pimedaks tavaliselt 4- kuni 6-aastaselt. Osadel tõugudel avaldub haigus juba noorel kutsikal. Kui tavaliselt pärandub PRA autosoomse retsessiivse geeni kaudu, siis kahel koeratõu, siberi huskyl ja samojeedil, ilmneb PRA soost sõltuva retsessiivse tunnusena. Eesti Siberi Huskyde

Humayun, a retinal surgeon at the University of Southern California, it drew on cochlear implants for the deaf and is partly financed by a cochlear implant maker. It is so far being used in people with retinitis pigmentosa, in which photoreceptor cells, which take in light, deteriorate. Gerald J. Chader, chief scientific officer at the University of Southern California's Doheny Retinal Institute, where Dr. Humayun works, said it should also work for severe cases of age- related macular degeneration, the major cause of vision loss in older people. With the artificial retina, a sheet of electrodes is implanted in the eye. The person wears glasses with a tiny camera, which captures images that the belt-pack video processor translates into patterns of light and dark, like the "pixelized image we see on a stadium scoreboard," said Jessy D.

Haiguse varasteks tundemärkideks on mikroskoopiliste moodustiste tekkimine silmas. Seni pole veel kindlaks tehtud, kuidas need moodustised tekivad ning kuidas nad mõjutavad haiguse kulgu. Värskest uuringust aga selgus, et need moodustised sisaldavad väga suures koguses tsinki. Uuringu juhtivautor dr. Imre Lengyel ütles, et kuna varasemad uuringud on seostanud

You cannot ask two blind imbeciles to cross a narrow bridge with no support, because you know perfectly well that there would be a disaster. Whatever it is, it must be in our genes – our inability to take care of ourselves, our dependency on others to take care of our every need. One must question the intelligence of a race of people which has seen how centuries of dependence on others have made them perpetual slaves and who then continue to build castles in the sky. DEGENERATION OF BLACK COMMUNITIES 32 You see, I have lived in America for 32 years now. It is sickening listening to Blacks who are always telling, you that they were the first to move into such and such neighbourhood, “when the whites were still here. Now the community or city has gone to the dogs. Dirty streets, corrupt officials, more crimes, less services and more taxes……etc., etc
30. The aches were turning into surgeries, small training injuries had become chronic pain, and we all recognized the pink elephant in the room: it was going to get worse. Much worse. For me, the straw that broke the camel's back was a series of high-dose prednisone prescriptions and epidural injections in 2009. It started with an innocuous shoulder impingement. MRIs showed no shoulder issues but uncovered cervical spine degeneration in five discs. "This is something you'll just need to live with" was the concluding remark, delivered with an inappropriate smile, from a spine surgeon who works with NHL and NFL teams. None of his recommended drugs or injections would x the problem. They were nothing more than Band- Aids designed to mask symptoms, to dull the senses. I had graduated to terminal pain management. My second day on prednisone, a strong immunosuppressant drug, I spent the entire afternoon
