Optics

LED lights and fiber optic trees are two energy-efficient technologies that can reduce your energy costs, particularly when the lights are used for long periods of time, such as in commercial applications. LED Lights Light Emitting Diode (LED) holiday lights are a new application for a mature technology. Each year since 2002, manufacturers have improved the choices, producing bigger and brighter bulbs and new color options. LED lights have a number of benefits over conventional…

on her bed with a pipe saying that it helps with glaucoma too. But is any of this true? Yes and no. Glaucoma does not affect the pressure in your head known as intracranial pressure or ICP. What it does affect is the pressure that is put onto the optic nerve, this type of pressure is call intraocular pressure or IOP. There are several different types of glaucoma that can have different symptoms and treatments. Although this happens mostly in adults over the age of sixty, it can happen at any…

Acoustic Neuroma and Optic Nerve Glioma The brain is a superhighway of complex and intricate systems that control every function of the human body, but what if something goes wrong? These are the cases of two interesting problems; Optic Nerve Gliomas and Acoustic Neuromas. Two forms of brain tumors that directly affect some of the body's most important functions sight, hearing, and balance. These tumors can affect the body beyond those in many adverse ways. Acoustic Neuromas, or AN’s for the…

INTRODUCTION The lamina cribrosa (LC) within the scleral canal in the optic nerve head (ONH) is thought to be the primary site of axonal insult in glaucoma.1-3 It is of interest in glaucoma to understand the anatomy of the LC and surrounding tissues and how they change with aging and disease. LC has been investigated using a variety of methods, including histologic section,4,5 detergent digestion of surrounding tissues6,7 and finite element modeling.8,9 In human glaucomatous eyes, LC…

While they are not necessarily given the credit they deserve, their achievements can be found in numerous different places, such as ordinary households to the largest hospitals around the world. To summarize, Al Haytham’s discoveries in the field of optics has allowed so many successors to create technologies using lights, eventually leading to the discovery of electricity. Al Zahrawi was a pioneer in the world of surgery, developing new ways to comfort patients and better operate on them. The…

the authors Ramdas, Wolfs, Kiefte-de Jong, Hofman, and de Jong (2013) of the article "Nutrient Intake and Risk of Open-Angle Glaucoma: The Rotterdam Study", Open-Angle Glaucoma is a progressive neurodegenerative disease that leads to glaucomatous optic neuropathy and eventually, through glaucomatous visual field loss, to the loss of sight. It is also the most common cause of irreversible blindness worldwide. Increased intraocular pressure, oxidative stress, and an impaired ocular blood flow are…

Glaucoma is a physical aspect of increased pressure on the optic nerve, which transfers to the brain, identifies it. The pressure could cause the damage for a foundation of vision loss. There is no exact know cause of the increased pressure other than genetics, rather than a combination of factors that could lead to early onset or risk for aggressive progression of the disease (Cascella, Strafella, Germani, Novelli, Ricci, Zampatti and Giardina, 2015). There are theories of risk factors that can…

Going to New York City of technology for a few years now, I started in 2013 I didn’t really know what major I really wanted to be in. I first thought I was going to do nursing or rad tech but the more I learned about the majors I was not really interested in them. Some of the duties you had to do especially for nursing really pushed me away from the major. So I recently became undecided in what I wanted to do. Out of nowhere I found out about Vision Care. I didn’t even know about this department…

The medication Plaquenil has been prescribed for the treatment of various illnesses that include malaria, rheumatoid arthritis, and systemic lupus. The purpose of this paper is to draw attention to the side effects that can damage the visual system. Even though the side effects cover a broad range, the results on the illness that Plaquenil is prescribed for outweigh the side effects. The side effects will impact individuals in different ways, depending on the dosage and the length of time that…

Marine Optics Vs Rifle Optics Whether you are an avid fisherman or a talented marksman, there are a variety of tools that can help you maintain and perhaps improve your abilities. This is especially true when it comes to your vision. There are scopes that can make your aim more accurate and ones that help you bring things from far away to things that are closer. There are also options that allow you to simply see things more clearly. Which type is right for you? Perhaps instead of telling you…
