Project 3-4 Chapter 3, pp. 114 Poor or high lighting can have various effects on the eyes. Such effects include eyestrain, dry burning eyes, eye irritation, blurred vision, and even headaches. However, the effects do not stop there. Other collateral effects of poor lighting can include stiff necks, sore shoulders, and sometimes even back pain due to people compensating (by taking on poor body posture) for the poor light when trying to read something under undesirable conditions. Standard lighting, fluorescent lighting, and full-spectrum lighting all have different effects. Studies have been carried out by the Light Right Consortium, who was managed by the Pacific Northwest National Laboratory. They were contracted by the Renesselaer Polytechnic Institute’s Lighting Research Center and the National Research Council of Canada Institute for Research in Construction. (Shadesbreath) Their analysis came to three conclusions. First, OSHA has minimum standard for office environment and lower standards for individual workstations. Secondly, there is no uniform lighting level that can optimize productivity. Lastly, non-daylight type lighting can have potentially negative effects on businesses in areas such as emotional/psychological issues in the employees; financially due to heat generation and overall energy consumption; and productivity and profits. OSHA has a standard of thirty foot-candles minimum for office lighting. Guidelines for workstations with monitors should have lighting that ranges from 20 foot-candles to 50 foot candles. However, if LCD monitors are being used, OSHA regulations call for up to 73 foot-candles of lighting. Washout of the screen due to bright lights, can lead to eye fatigue. To combat this, it is recomme... ... middle of paper ... ...June 29, 2010, from Mercola.com: Take Control of Your Health: http://products.mercola.com/light-bulbs/ Occupational Safety & Health Administration: Workstation Environment.

All are relevant to the film that I will be applying the study of lighting
For new or retrofit construction, every choice can lead to energy savings; energy that is derived primarily from fossil fuels. The typical household LED replacement for a 60w light lasts about 50,000 hours. Pretending that an incandescent could also last that long, it would consume about 3,000 kilowatt-hours (kWh) of energy whereas the LE...

This paper will show how the facility will continue to stay abreast of the Occupational Safety & Health Administration (OSHA) standards. The paper will also take a look at the activities and the frequency of training and audits that the hospital will conduct throughout the year. This paper will address the possibility of the fines the hospital has received and what causes the fines. The OSHA is an organization that provides a safe work environment for all staff members.
Many chosen profession have distinctive expectations which are important to both employers and employees. Companies are looking for ways to preserve the environment and go green in their work environment. Along with this they are required to adhere to safety factors using Occupational Safety and Health Administration (OSHA) standards that your particular career must follow. OSHA regulations consist of standards designed to guarantee the American workplace is free of safety and health hazards. OSHA, or the Occupational Safety and Health Administration, is a division of the United States Department of Labor that enforces the Occupational Safety and Health regulations.
Proper ergonomic conditions prevent injuries to workers and allow them to work efficiently. Ergonomics reduces costs. Workers that do not have a good ergonomic workspace can suffer from pain and uncomfortable posture which is dealt with money spent on treatment. In Canada $800 000 000 per year goes to ergonomic related injuries. Appropriate ergonomic workspaces create an anti-injury space for workers. Ergonomics also increases worker’s productivity by designing a work place with good posture, good heights, fewer motions, and less exertion. Thus making the workspace more efficient for the worker. Ergonomics also

More focus is necessary on the indoor environment in schools, day care centres, hospitals and nursing homes for elderly, because children, hospital patients and elderly are sensitive subgroups. There are a number of indications that the indoor environment at home is normally worse than in the indoor office environment. The population spends most time at home, and children are exposed at home for many years (National Safety Council, 2009). This suggests that improvements of the home environment may be a cost-effective to reduce the indoor exposure burden in the population. The link between indoor and outdoor air pollution should not be ignored, as most of the exposure to outdoor pollutants occurs indoors. Finally, the function of energy saving and climate changes for the indoor environment and SBS will be an important future issue.

The size of the pupil is firmly linked with the visual acuity. Visual acuity has improved because background lighting rises up to 3400cd/m caused by the blockage of the paraxial ray. Therefore, the peripheral shape of the cornea is require to be controlled in order to deliver more light into the eye.
In order to keep up with current Occupational Safety and Health Administration (OSHA) requirements, employers must ensure they take all the aspects required into consideration and educate their employees on the security and safety measures to be taken as well as updating them on the procedures relevant to their duties. OSHA is in charge of upholding and conducting standards measures that are lawfully imposed by the state and federal agencies. It requires every company to have well educated, trained employees on safety issues and who are able to apply these training into practice to ensure they achieve a healthy working environment. Employees need to be educated on the safety of the equipment they use in their place of work too.
we can’t see in the UV spectrum, and there are other animals such as butterflies which have 4 or 5 different photoreceptor types and can see more colors than us
Other indications may cause more damaging ailments. Examples include double vision and headaches while reading a book or working with a computer. In some cases, individuals can also experience confusion on colours and glare even just in usual lighting. As soon as you experience these issues, visit your eye doctor and obtain a standard vision test.
Monitor radiation has been discussed throughout computer journals for years. I have learned that different monitors have higher or lower radiation levels. Monitors made overseas are generally considered to have a lower radiation level than those built in the United States. For example, as an engineer the Management Information Services (MIS) unit told us that NEC monitors had much lower radiation levels than IBM monitors. After sitting at a computer during my eleven-year career as a Civil Engineer with the Los Angeles Department of Water and Power, I often found that headaches at the end of the day were common. My eyes felt strained due to the looking at a monitor for an extended period of time. Over the years as an engineer I bought various types of glare screens for my computer monitor. Even though I doubt the glare screens help with the reduction of radiation given off by the monitors, they do seem to help with eyestrain.
The incredible thing about the human eye is that it can see objects to as far as 2 miles long.That’s almost 35 football fields! Let’s consider the mechanics of the eye. The eye is a clear ball with water-like fluids in there.You have the front of the eyeball which is translucent called the cornea. It’s extremely thin and its job is to protect the eye by refracting light that comes through. The next part of the eye is the pupil, which mostly everyone knows about.It is the black portion in your eye. Did you know that it gets its color from when light entering the eye is absorbed and it doesn’t leave the eye. You may also notice that when you’re looking at the pupil, you can see a different colored circle in them. This is called the iris, and it varies among everyone. Your actual eye color is determined by a pigment in the iris.The genes from your parents set a human’s eye color. The iris’s job is to widen or close depending on how bright or dark it is. If its bright and the sun is basically beaming down on you, the iris will adjust so your pupil will get smaller to only let a certain amount of light in. If you’re in the dark, your iris adjusts so your pupil will get bigger so a greater...

This happens to people who use computers everyday for long periods of time. Children ages of 10-15 have complained for loss of vision over the past year.
