Eye

often take our ability to see for granted. We rarely think about what process our eyes and brain must complete in order to view something as simple as a movie or lecture slide. In fact, such a small part of our anatomy is made of greatly complex procedures The operation system of the eye is very complex and one can easily stray from track when discussing how the eye works. First, the cornea is a part of the physical eye that helps reflect and bend light in a way that makes it possible for it to…

Have you ever dealt with dry, itchy eyes? They may sting, or feel gritty or overly sensitive. This is a common condition that affects as many as one in three people. Also known as keratitis sicca or xerophthalmia, dry eyes can result when tear fluid is produced too slowly or evaporates too quickly. While it’s common to ease discomfort in the obvious way — by adding more fluid to the eyes in the form of eye drops — it’s important to investigate what’s behind this seemingly simple, yet…

The magic of vision is incredible. Through the small window we are able to see the whole world. Eye is one of the five senses what human possess and majority would agree that it is perhaps the most important one. Many of us would be intrigued by the composition of the eye and even more by his interconnection with brain. How the eye actually works, his structure and the function will help us in better understanding how visual light is converted into our perception. The challenge of the image…

Dry eyes is a common condition that occurs when your tears are not able to provide adequate lubrication for your eyes. Tears can be inadequate for many reasons. For example, dry eyes may occur if you do not produce enough tears or if you produce poor-quality tears. Dry eyes feel uncomfortable. If you have dry eyes, your eyes may sting or burn.

“Beauty is in the eye of the beholder,” implies that beauty is subjective and that one decides what is beautiful and what is not. However, there are things that are objectively beautiful that were created by God. Beauty fits into Christianity because of these inherent beauties, as seen, in nature, in things that are symmetrical, and in things that have order. Inherently beautiful things were created to draw our attention to value and importance in God’s design. First, God created nature to be…

Eye Melanoma Eye melanoma is a form of cancer that affects the cells that give the eyes their color (pigment). These cells are also found in the skin and hair. Eye melanoma is rare. Melanoma of the skin is much more common. Eye melanoma usually starts in the middle layer of the eyeball (uvea). This part of the eye includes the iris, which is the colored area around the pupil. Healthy eye cells may develop genetic changes (mutations) that cause them to grow out of control in the eye. Eye…

housefly look at the world in quite a different way than humans do. The structure and function of a fly's eye are completely different from humans; therefore they see the motion, shapes and colors differently than humans. Flies also see the light in a different way than humans. Nano-structure of the eyes that gives the ability of a virtually 360 degree all direction vision with only two eyes placed at the front of the head. Military pilots like helicopters and fighter jet pilots often suffer…

“Bionic Eye” can be dated back to 1755. Before the many vaccines and treatments we have today, when highly spreading epidemics would occur, patients would become blind due to high fever. “French scientist Charles Leroy discharged the static electricity from a Leyden jar, into a blind patient’s body using two wires. One tightened just above the eyes and the other wrapped around the legs. The effect of this caused the experience on a flame like sensation passing downward in front of the eye.”1…

glasses and contacts every year or so can be costly. The solution to the problem for glasses-wearers is laser eye surgery. Unfortunately, the surgery is not the most affordable for everyone, ranging from $400 per eye to almost $2,000 per eye. It depends on the clinic, doctor, risk, and other factors. Furthermore, traditional group health insurance does not always cover the cost of laser eye surgery, as it is not considered a necessary procedure. Some plans reimburse a certain amount of money,…

Introduction Eye enucleation is surgery to permanently remove the eyeball (globe). The space that remains (socket) after the eyeball is removed will be filled with an artificial eyeball (implant). Muscle tissue will be sewn onto the implant to keep the implant in place and to give it some movement. The natural eyeball may need to be removed because of: Injury. Diabetes. Tumors. Eye disease such as glaucoma. Inflammation or infection of the inner eye (endophthalmitis). A painful, blind eye.…
