often occur as a symptom or sign of undiagnosed diabetes. Fluctuations in blood sugar can in addition give rise to some alterations in the refractive error as a result of osmotic changes within the lens. With the absorption of water into the lens the eye becomes more hypermetropic. Regardless of the magnitude or direction of the changes, the refractive status tends to normalize within weeks of initiation of treatment of diabetes Changes in color vision; Color vision changes may precede the development

a new study about a secretion from stem cells that is very eye opening! Stem cells are used in lots of studies today due to their ability to transform into any type of cell, but they can also cause complications like rejection. Stem cells contain small membrane bound packages that are known as exosomes. They are filled with proteins and can be used to signal other cells to begin producing certain proteins. Researchers at the National Eye Institute studied the roles that exosomes played on retina

Glaucoma is a group of eye diseases characterized by increased intraocular pressure, resulting in atrophy of the optic nerve. (Venes, D. 2013) This disease is known to gradually cause the loss of peripheral vision which can eventually lead to total blindness. Glaucoma is the third most prevalent cause of visual impairment and blindness in the U.S, although the incidence of blindness is decreasing due to early detection and treatment. (Venes, D. 2013) Glaucoma comes in two major categories: closed-angle

BECAME WELL KNOWN FOR HIS WORK IN RESTORING EYE VISION FOR COUNTLESS AMOUNTS OF PEOPLE IN AUSTRALIA, AS WELL AS MANY OTHER COUNTRIES AROUND THE WORLD. IT IS ESTIMATED THAT MORE THAN ONE MILLION PEOPLE WORLDWIDE CAN NOW SEE TODAY BECAUSE OF INITIATIVES INSTITUTED BY FRED HOLLOWS - THE MOST NOTABLE EXAMPLE BEING ‘THE FRED HOLLOWS FOUNDATION’. GROWING UP, HOLLOWS ALWAYS WANTED TO BE A MISSIONARY, BUT A STINT WORKING IN A MENTAL INSTITUTION OPENED HIS EYES, AND CONVINCED HIM TO FOLLOW A CAREER IN MEDICINE

shield that protect your eyes from hazardous work and home environments. The most common hazard is flying projectiles from operating power tools or machinery. Others include harmful dust, splashing chemicals, laser light, and radiation. However, a poor fit compromises your eye safety in a number of ways. These include: Eyewear Gaps The gap between the protective lens and your face shouldn't exceed one-third of an inch (about the width of a pencil). Large gaps expose the eyes to hazards coming from

book on his tablet computer when the words began to look “fuzzy.” In addition to the blurred vision, he also experienced a “strange feeling” in his right eye. The following morning, he had difficulty opening the right eye. Using his fingers to open the eye, he had double vision. Along with the double vision, he also experienced pain in both eyes, which worsened when looking left. His wife drove him to the on-post emergency

The next structure of the eye is the retina it is responsible for the viewing of images in other words it is responsible for your ability to view the external environment around you. The retina which is the “third stage of the eye” (Segre, 2015) is essentially a light-sensitive tissue. The functions of the retina mirror that of a camera 's film roll in which the retina sends a stream of chemicals which move from various areas of the eye eventually creating the image that you see. The entire retina

The world today has many different types of living organisms. Each species has a specific eye type that is unique to their kind. Here we will discuss the differences between the eye mechanisms of aquatic and terrestrial animals versus the four-eyed fish. The most common eye type which is ideal for image vision is camera-type eyes. Terrestrial animals consist of animals that live mostly on land such as flies, cats, dogs, bears, deer, cows, tigers, humans, etc. Aquatic animals consist of animals which

Figure 2 consists of two histograms (Figure 2A and Figure 2B) depicting the ocular dominance distribution of cells in the left visual cortex of two kittens born of the same litter.

single image. And an octopus’s eye has no blind spot. Each of these species’ eyesight has evolved overtime to adapt to survival needs. Most individuals take for granted their ability to see. Eyesight is a major connection to the outside world; around 80 percent of impressions are through sight, meaning that only 20 percent are from the other four senses. The human eye has evolved over time to turn into what it is today. Through human’s needs for survival, the eye has changed to suit humans. Two
