Third eye

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…

I have been mesmerised by the level of depth and complexity involved in the human eye. Being able to examine the retina alone can lead to the diagnosis of many life-changing illnesses from diabetes to glaucoma. This has left me fascinated as optometrists can come about crucial discoveries by just looking into the eyes, and therefore the work of an optometrist is somewhat similar to a detective’s investigation. Additionally the work of optometrists has resulted in shaping the lives of numerous…

The Draize test, devised in 1944 is a widely used test that predicts human ocular irritancy by using laboratory animals, primarily albino rabbits. A substance is applied directly into the albino rabbit’s eye or to the surrounding skin to identify its likely effect on the corresponding human tissues based on direct visualization (Mitjans, Infante & Vinardell, 2008). Due to advances in ocular technology, the precision, validity, need and relevance of the Draize test is being challenged…

- 8). Auditory patterns include tone and intonation;volume, articulation, and stress patterns; and pace.Winston (2017) indicates that visual patterns include movement of the head; raising and lowering of eyebrows; gazing and blinking of eyes; opening of the eyes;movement of mouth; movement of shoulders; movement of torso; and use of hands. Humans have many habits; some of these habits are associated with verbal communication. For instance, my pastor often does what we call a “Bob Hope” pose…

eighty-four-year-old neighbor, Colette, has come to me to talk about how she is having eye complications after a recent fall to the head. After reviewing the symptoms, I think Colette has damaged her oculomotor nerve, cranial nerve IV. Furthermore, the inferior rectus is in charge of depressing, adducting, and laterally rotating the eye (Schuenke, Schulte, & Schumacher 2016). Similarly, the inferior rectus muscle positions the eye infraversion, dextrodepression, levodepression,…

Glasses have changed over the years and they help us see the world clearly. I believe knowing how the eye works, the different types of corrective lenses, and discovering the types of distorted vision, helps us to be able to obtain better vision. First, during the 1400s glasses were created (Klein). Around 1500 Johannes…

There’s writing over his torso area, the first line is in red writing in a block letter type of format, then the second line is in a regular white writing. The Third line of writng is in bold, emphasizing that TODAY is an important key term; then the last line is smaller text then the others to give you an option. There is also a box frame all around the advertisement and a small opening where the…

Procedure of LASIK: First, the eye is numbed with a few drops of topical anesthetic. An eyelid holder is placed between the eyelids to keep them open and prevent the patient from blinking. A suction ring placed on the eye lifts and flattens the cornea and helps keep the eye from moving. Once the cornea is flattened, a hinged flap of corneal tissue is created using an automated microsurgical device, either a laser or blade. This corneal flap is lifted and folded back (figure 1). Then the excimer…

It has been about two decades since the world`s first smartphone was introduced to the general public. Since then the smartphone has been a part of life among most people in the world. Online statistics show that more than one billion smartphones have been sold and are being currently used by people across the globe which may even be more in number due to un-registered number of smartphones sold in the black market. Smartphone operating platforms have innumerable number of applications which…

prisoners, gets face to face with Louie and either says “Don’t look me in the eye”, after beating him for looking him in the eye, or asks “Why don’t you look me in the eye?” (Jolie, Unbroken; Coen108). Each time, Louie refused to look his captor in the eye, and instead either looked him in the face, but not the eye, or simply kept his head down (Jolie, Unbroken). However, the third time this idea of looking Watanabe in the eye comes up, the situation is much different. “Don’t look at me. Don’t…
