Photographic lens

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…

At Atlantis Vision Center in Indian Harbour Beach, FL, we often get common, yet important, eye care questions. One such inquiry is the meaning behind the term “20/20 vision.” This term expresses normal visual acuity (in other words, the sharpness, or clarity, of vision) measured at a distance of 20 feet. People with 20/20 vision can clearly see the objects that should normally be seen at 20 feet. However, 20/20 does not necessarily mean perfect vision. The term only indicates the sharpness…

light will travel through the aqueous humor which is a watery substance between the cornea and lens. Once the light hits the lens, attached to the ciliary body, it is focused onto the retina. The ciliary bodies pull on the edge of the lens in order to change its shape so that it can focus the light onto the retina correctly. The third mechanism requires the correct focus of light onto retina by the lens. As the light is being reflected onto the back of our eyeballs (retina) it is traveling…

A light microscope works like a telescope using glass lenses to reflect light, which magnifies images which are naked to the human eye such as cells and dust. The lens closest to your eye is called the eyepiece lens. This usually has a magnification of x10. Objective lenses are lenses of several different strengths which magnify the image. The stage is the place where the microscopic slide sits. This is held in place by the clips. The light source (can be a mirror or a bulb) projects light onto…

The Effects of My Corneal Ulcer I was a contact wearer and I wore contacts for about four to five months until something execrable occurred. I thought it was just a common pink eye but, later found out that I had contacted a corneal ulcer which I knew would probably change my life forever. The use of contact lenses resulted in a corneal ulcer that contributed to the loss of my eyesight. I have regained my eyesight but I still have trouble seeing. If I didn’t go to the…

Introduction A lens is an object that forms images by refracting light. The images formed can be magnified, real and virtual depending on what lens used and the set-up of the lens system. There are two types of lenses, converging and diverging lenses. Converging lenses cause parallel light rays to converge to a point. Diverging lenses cause parallel light rays to diverge. Typically converging lens are thicker in the middle and diverging lenses are thinner in the middle. Lenses are used for many…

We have already come so far. We have come from a time where film cameras and VHS tapes were the latest items. We have very much gone above and beyond what some ever thought possible. The technology we have now surpasses what we once thought scientists could do. Technology has made it possible to communicate with loved ones from miles away, and just by a swipe of a screen. There have been so many fun items that have come from technology, such as film cameras to digital cameras. The advancements…

Over 100 years before Kohler Co’s 1998 recapitalization, they began as a humble, family-owned plumbing fixture manufacturer created by John Michael Kohler. Through years of acquisitions and diversification of products and services, Kohler grew into a billion-dollar company. Released in 1997, Kohler had expanded its focus to four key sections: on “kitchen and bath, power systems, interiors, and hospitality and real estate.” By 1984, Kohler had 500 million in sales, and eventually grew to 2.2…

Learning the fundamentals of digital photography is relatively easy. However, there are specific skills and techniques that you’ll only be able to develop well with time and experience. Ask any pro and they’ll tell that it’s probably taken them years to build up their bag of tricks. That being the case, you’d be hard pressed to find some pros that are willing to share with you their special tricks. But don’t worry. We’ve got you covered. We’ll be sharing with you all the photography tips the…

Before the camera was invented it was really difficult to record an image. You had to stand very still for a long time for the picture to be taken. If you moved just a little bit the picture would turn out blurry. In the year of 1881 George Eastman started making dry plates (Dry plates were round disks that were used instead of film). Then in 1883, George Eastman created a thin strip of paper covered in gelatin emulsion and silver balide, which is what we call film. Finally, he invented the…
