Importance of Getting your Eyes Checked I. Introduction A. Attention Getter – When was the last time you had your eyes checked? I hope within the last year. B. Relevance Statement – For most people they feel that they can see so they don’t need their eyes checked, when in reality that statement is false. C. Credibility Statement – I have researched these diseases and have sat through training classes learning about each one, since I work in the field. D. Thesis - Its important to get your eyes checked

understanding of how lenses affect the pathway of light. Through gaining understanding of this concept, we gain also gain and understanding on how lenses affect images and our own eye sight. Finally, this lab teaches us how to calculate the focal length of a lens. I was already fairly familiar with the concepts of this lab with the exception of how to calculate focal length and terminology such as object distance and image distance. In steps 2-3, my group found a focal length of 15.8 cm. In steps 4-12, my

We all know that having good eyesight is fundamental to driving safely. The often quoted standard for having good eyesight is the measure we know as 20/20. But what does 20/20 mean? To understand that you must look at a Snellen Chart. That’s the name of the collection of letters displayed in ever decreasing sizes on the wall chart used by Ophthalmologists and doctors’ to check your vision. The chart is named after its inventor in 1862, Dr Hermann Snellen, a Dutch Ophthalmologist.Snellen The fractions

Additionally, beam hardening happens as the energy levels of polychromatic X-ray beams used with the CBCT are not uniform, so the lower energy photons can be absorbed easily at the edges of the scanned area causing hardening of the X-ray beam, which resulting in lower gray values toward the subject center causing what is called cup¬ping artifact even if the density all over the subject is identical (91) Ring artifacts caused by defects or un- calibrated components in the detector forming concentric

through the lens will have fringes of color surrounding them. Lenses have distortion, too. With the Newtonian design, there are

The first lens creates the image and the second enlarges the object. Tripod Having a tripod is important in macro photography because it helps keep the camera stable while being so close. This helps prevent the picture turning out blurry or unfocused. 7 steps

Have you ever went to a 3D movie, in the 2000’s and looked at the screen with no glasses, And the screen was red and blue. Also those glasses hurt your ears if you put them on for a long time. It is time to explain how they work. Have you ever wondered how 3D movies worked. It is the same thing as the most popular 3D toy is called the “View-Master viewer”. The “View-Master” Is like a binocular but there is some thing in the way like a image. The “View-Master” uses images from a places or a

magnification, 1) the ocular, or eyepiece lens that one looks into and 2) the objective lens, or the lens closest to the object.” The source said that usually you will find 3 or 4 objective lenses on a microscope. Moreover, the source said that you would need a relatively sophisticated microscope with an Abbe condenser to have a good resolution at 1000x.

in the eye and forms a sort of cloud in the natural lens of the eye that could eventually lead to blindness if not treated properly. This type of cataract is different from most cataracts, since congenital cataracts is present in an individual since birth, meaning that it was most likely inherited from the parents. The way that it is inherited is by some sort of abnormality, which would transpire during the making of the proteins that make the lens clear. There are many different

1. What is aperture priority mode? When might you use this mode on a camera? Aperture priority mode lets you control the aperture while the camera adjusts the rest of the settings. You would use this mode when you want to control the depth of the field and there is lots of light. 2. What is depth of field? How can you adjust the depth of field in a photograph? The depth of field is the focus amount in the photo. You can adjust the field depth by aperture. A larger aperture creates a smaller field
