Product: Ray-Ban PROBLEM STATEMENT Various eye problems have been associated with overexposure to sunlight. CAUSE Ultraviolet Ray WHY? People are unaware of what UVR can cause to their vision/eye sight. WHY? Insufficient spread of information to the public. Sub Problem How can we completely inform the public about the dangers caused by the UVR? INTRODUCTION Another radiation from the sun can harm not only your skin but also your eyes. Extended exposure to the sun’s UV rays has

melanin is to act as a defensive barrier of the skin against radiation damage. Ultraviolet light between the wavelengths 280-320nm (UV-B) causes sunburn and damages the skin on nonpigmented peoples. Exposure to this degree of light causes their skin to become dry, leathery, and wrinkled in appearance similar to that associated with aging. This can be seen in Whites living in Australia and South Africa, where ultraviolet light intensity is high because of the relative latitude or closeness to the equator

produce melanin which is what gives your skin its color. You can also get melanoma in your eyes and internal organs but it is very rare. Nobody really knows the cause of melanoma exactly but they have come to the conclusion that you can get it from ultraviolet radiation from the sun, tanning beds and tanning lamps. Anyone can get melanoma at any point in their life but it seems to be higher and increasing in people under 40 years of age and older. Women are especially known for getting melanoma. Melanoma

Australians are more prone to skin cancer than any other form of cancer. Skin cancer occurs when the skin cells are damaged due to over exposure to ultraviolet radiations. There are three types of skin cancer melanoma, basal cell carcinoma and squamous cell carcinoma. Over the past few decades the number of skin cancer has risen in Australia. Anyone can be at risk as chances increases as you grow older

of melanin disorder. The internal causes are inborn. For instance, darker skin people often have melanin disorder and hyperpigmentation. The ultraviolet rays damage the melanin and strains, freckles and age-spots appear. These strains usually appear on the hands or on the face, but they can also appear at any area of the skin that was exposed to ultraviolet

six miles above the Earth’s surface to 31 miles. In the stratosphere the ozone layer acts as the earth’s sun screen; as ozone take in solar ultraviolet radiation strongly, especially at wavelengths less than about 310 nm in the ultraviolet-A and Ultraviolet-B parts of the spectrum. Ozone thus acts as a strainer, preventing potentially detrimental Ultraviolet radiation from reaching the surface which can causes skin cancer and genetic damage. (Hester, Ronald E, and Harrison, Roy M, eds. Causes and

OZONE DEPLETION BY HUMAN’S ACTIONS The ozone layer is a very important component in the atmosphere. Ozone is not the same as the oxygen humans breathe. There is very little of this gas in the atmosphere. First off, let’s begin with a definition of the ozone layer. Ozone is a hot, slightly bluish gas. It is a molecule made up of three oxygen atoms, which are very similar to the molecule we are familiar with (O2), the molecule needed for human respiration. Despite the major smog problem

Sunburn Overview Skin lesions resulting from excessive exposure to radiation or without adequate protection from the sun. The sun's rays come to earth in the form of ultraviolet rays, UVA and UVB. Both types of rays are potentially dangerous because in dose excessive can damage the molecular structures of cells, particularly those of DNA. Even X-rays, applied in small doses, can lead to sunburn. This is manifested by a reddened area, due to a greater flow of blood to the stimulus exerted by the

is determined by the spread of patches across a person’s body and overall severity of the case. Progressively with more treatments, the dosage of psoralen also increases, adding more and more sensitivity properties to the melanocyte cells. The ultraviolet light therapy, PUVA is currently the most effective at treating vitiligo21. Physicians often perform PUVA light therapy alongside the usage of topical treatment in order to better enhance the effects of the light

Hello, my name is Sophie Rees and I am here to talk to you all about the charity I work and support for, The Cancer Council. The Cancer Council is one of Australia’s largest independent funders of Cancer Research. Over $70.5 million dollars of research grants totalled in 2015 and this was a major help to us as an organisation. Our organisation straight up funded a huge $48.1 million dollars with also an addition of $22.4 million, which was used for our research funding partners. We provide early
