Corrective lens

for processing and interpreting sensory information in the environment, making them crucial features for many organisms to survive. The eye serves many functions, most of which are associated with a specific structure of this organ. For example, the lens, cornea, and iris are necessary for the optic capabilities of the eye. Light sensing is performed by photoreceptors located in the retinal pigmented epithelium. Transmission by the eye is performed by the retina and the optic nerve. Lastly,…

Shot #1: I zoomed in on the roof of our chicken coop to illustrate horizontal lines. The chicken coop is built with all the lines listed, however, the longest of the lines, are horizontal. So, the horizontal lines made for the longest shot time. Shot #2: I focused in on the gold stitch, the other toys in the background blurred, creating the depth of field visual element. Shot #3: I zoomed in on tree bark at a local park to illustrate texture. Shot #4: I zoomed in on a building window arch to…

When looking at a flashlight, it can be determined that the flashlight itself resembles a parabola. Flashlights are supposed to be able to focus on a single point, which is infinitely small. Since a flashlight is supposed to mirror a parabola, the flashlight has similar components as a parabola. The filament, which is the part of the flashlight that gives light, resembles the focus on a parabola. The filament is a three dimensional object so it is infinitely larger than a point, yet the filament…

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?

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…
