Blue light

Transcript: By: Anna Cain Blue Light The light that comes from the sun appears white, but it is actually made of every color of the rainbow. As light passes through a prism, the light is separated into all of its colors. The prism is a specifically shaped crystal. Light energy travels in waves. Some light travels in short waves, and others in long waves. Blue light waves are shorter than red light waves. Sunlight reaches earth's atmosphere and is scattered in all directions by the particles and gasses in the air. The blue light is scattered more because it travels in shorter, smaller waves. This is the reason the sky is blue majority of the time. Why the Sky is Blue Why The Sky is Blue Blue light, or high energy visible (HEU) light, is a type of light with short wavelengths emitting a higher energy. It has one of the shortest, high energy wavelengths on the spectrum. In natural sunlight, blue light is always visible, but blue light is not only in sunlight. TV's, computers and phones use blue light for their screens. What is Blue Light? What is Blue light? Pros and Cons of Blue Light Pros: Blue light can help boost alertness Boost memory and cognitive function May even elevate your mood Cons: Can lead to eye strain Could lead to damage in retina cells (Cells found in the eye Potential molecular degeneration - Blurred or loss of vision Leads to sleeping issues, restlessness Blue light can disrupt your biological clock To an extent, blue light can lead to cancer Pros and Cons of Blue Light Blue light is both good and bad, and the difference is balance. If you only expose yourself to a limited amount of it, there will be positive effects, such as mood elevation. But, if you expose yourself to too much, all of the negative impacts will take effect on you, such as eye strain, molecular degeneration, and others. If you find the right balance, blue light will be safe to use. The Difference The Difference Protection Against Blue Light Protection Against Blue Light One technology used to prevent blue light reaching your eyes is a type of screen protector. This thin, clear screen protector has a blue light filter on it. Therefore, the blue light does not go through the screen and to your eyes. Another technology used today is blue light glasses. These glasses have a blue light filter in the lens. When you wear these blue light glasses, the negative effects and rays will not reach your eyes. Biological Clocks Biological Clocks Biological clocks and circadian rhythms are connected to blue light. Biological clocks and circadian rhythms is an internal mechanism that controls the psychological activities of yourself. It can change daily, weekly and yearly. They are connected to blue light because when you are exposed to blue light, it alters our biological clock, which is the reason that when you are exposed to it, you have troubles sleeping, and your internal schedule is altered. Sunlight contains both ultraviolet (UV) light and blue light. UV light is part of the non-visible light spectrum. Everyday, when we are out in the sun, we are exposed to UV light. It can cause damage to our eyes, specifically the lens and cornea. UV light can cause sunburn and destruction of vitamin A. It can lead to skin thickening, wrinkling and possible damage to DNA. Blue light, which is part of the visible light spectrum, goes deeper into the eye, and can cause permanent damage to the retina, which leads to problems such as molecular degeneration. In conclusion, UV light is more negatively damaging to the whole body, and blue light only takes effect on the eyes. Blue Light and UV Light Blue light and UV Light

The blue light filter that you can turn on isn't as bad for you eyes but it is no means good for your eyes. Phone Computers 2 For the computer there are a couple options. For one there is a custom screen that you can buy for your computer, but they are pretty expensive. They is also a blue light filter but it is pretty hard to find on your computer. Computers How are the concepts of biological clocks and circadian rhythms connected with blue light By Garrett Colten How are the concepts of biological clocks and circadian rhythms connected with blue light Blue light has a fliccering patterm that effects your circadian rhythm. Your circadian rhythm is your own biological clock which effects your daily, weekly, yearly cycle. 1 Your Circadian rhythm Biological clock- Your biological clock is a mechanism that controls your physiological activites on a daily basis. Circadian rhythm- Your circadian rhythm is your 24 hour clock inside your body which controls a physiological process of living beings. Meaning of your Biological clock and your circadian rhythm 2 How do the effects of blue light compare to the effects of UV light How do the effects of blue light compare to the effects of UV light Benifical Vitamin D production Strengthens your immune system, bones and muscles Stimulate melatonin production Enables a regular sleep cycle Bad 90% of skin cancer comes from UV radiation Damages eye tissue Ages skin UV Effects UV Effects Blue Light Blue light Effects Can be helpfull to people sufering with depression, most of the time with people having trouble acepting that the season is changing.

On the community: Build positive relationship between the police and the society Relieve social tension Encourage good social behaviour The police/youth relation may be get worse if youths fail the programme or are uninterested/unmotivated to complete the course. Creative collaboration (Sawyer, 2014, p232) Generate novel ideas According to the latest Statistics New Zealand data, the youth apprehension rate has dropped 35% since 1994. There were 29,153 apprehensions of 10- to 16-year-olds in 2012 compared with 40,560 in 1994. Creative activities What is Blue Light? voila!! "Where does the purpose come from?" What kind of creative process is being undertaken? A registered charity that works in partnership with the police deliver an extensive range of youth programmes and activities has been active in NZ for 30+years has 74 branches nationwide. Communities can... The end purpose is to... if youths are unmotivated there could be a greater chance of them relapsing into problem behaviours such as interacting with the wrong crowds. Positive impacts Empower the youth population by enhancing community well-being and creating positive relationships between the youth, the community and the law enforcement. Regular check up sessions with previous participants to ensure that they have maintained their progress. This also helps to maintain the positive relationship with the police. Youth form community of identity Blue Light form community of attachment (Willmott, 1989). Example: [nzherald] - Aaron Kingi, a young adult who had begun using drugs and drinking alcohol from 13, was saved by Blue light who attended a holiday programme.

Participants could be paired with a mentor with a similar background, who can provide guidance and be friend. Blue light continued..... - PCT fear factor Youths may not regard the programme as an opportunity to enhance their potential career pathways or as a way to rebuild their life but instead may see it as a punishment. On individuals: Life skills Enhancement Positive establishment of three views Can reduce the rate of youth crime Be based on location, interests or identity Have positive influence Have negative influence (Nicholson, 2014, p.85) Implement less coercion, and treat youths more like adults rather than kids. enhance youth life skills, educational possibilities, broadening social communications, cultural and sporting activities reduce drugs,alcohol use and reducing violence among youth Creativity in community based on location St George Street Speaks by Kat Thomas Film Project 705 by FM Theatre Power Projects like these aid to strengthen community based on location. - Blue Light’s own children’s TV show ‘Bryan & Bobby Regarding their approach, courses in Blue Light should seem less like a punishment, and focus more on instilling a sense of responsibility within the youth who has the power to change their own life. Creativity based on common interest or identity Volume: a music mentoring programme for youth Rewrite: a youth arts and social justice charity They also form a community of attachment.
