Contact lens

has come, scientists have created a type of bionic lens that allow humans to zero in on the tiniest of objects without the assistance of a third item such as the microscope. For hundreds of years, scientists have been using the microscopes to make major discoveries such as proving the existence of minuscule living organisms that cannot be seen to the naked eye. However due to the physical laws restricting light to pass through conventional lens to see these small items, we had begun to be…

When a lens produces an image, the size of it corresponds to the focal length of the lens. The smaller the focal length, the smaller the image and the longer the focal length the bigger the image. How bright an image may be solely depends on the amount of light collected by the objective lens. How much light can be collected corresponds to the area of the objective lens. So the bigger the objective lens, the more light can be collected. If you want to increase the light gathering power by 4, you…

I did not expect to see a difference between object and image distance. But that was the important factor that resulted in knowing how the light rays would pass through the lens. I also did not expect for the light to be affected if there was a shed of light in the room. Turns out, it makes a really big difference by doing so. As part of doing an experiment, it is very crucial to show as much evidence as possible in order…

1. look of the photo you are taking by altering the natural colors, or enhancing certains points of shadowing or lighting. 2. What is a polarizing filter? What benefits does one have for photographs? Polarizing filters improve the saturation and make the colors appear deeper and saturated. Instead of seeing a glare or uneven lighting. 3. What is one piece of equipment that should be used, if possible, for panoramic photography (in addition to the camera)? Why? A tripod is an important piece of…

While preparing for the hunting season the most important thing that you need to take along are a quality pair of binoculars. Quality binoculars will assist the hunter in two very important ways. 1) The enjoyment of the outdoor experience will be greatly increased. Binoculars will help the hunter to spot the game he is hunting and also to view the scenery that he might have missed otherwise. 2) The hunter's chances for a successful hunt will be much higher with a pair of quality binoculars.…

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…

Micolens are small lenses with a diameter smaller than 1 mm, they can work by diffraction, refraction or a combination of these two. When arranged regularly on a single substrate they form a microlens array. In order to be considered a good quality lens, microlenses must have qualities such as to low wavefront aberrations, consistency of focal length and pitch across the array, durability and low price. (Daly 2001) Microlens arrays have several applications, such as CCD arrays, digital…

theater, from spectacle, to enter into direct contact with life. But life is also theater, life is also spectacle” (Chronicle of a Summer). Ultimately, both the camera and Rouch are facilitators in provoking performance, however, he reaches a deeper truth within his subjects. In the end, Rouch met his goal of exploring what film can achieve, revealing a transformation that prompts itself turning subjects into actors when placed in front of the lens of a…
