Random Facts on Pink Eye
In some parts of the world, it is summer. During summer, diseases can be acquired and of them is pinkeye.
Conjunctivitis or pinkeye is a kind of eye infection.This is inflammation of those sensitive lines inside the eyelid and on top of the eyes. Some of the causes are bacteria, viruses, allergies, pollution and other irritants.
The symptoms of pinkeye are the redness of the white part of the eye, the redness and swelling of the eyelids.It includes continuous flow of tears and the sand-like feel inside the eyes.
Because of the continuous flow of tears, the eyelids stick on each other when they dry especially in the morning upon waking.
To avoid getting pinkeye, refrain from using personal things like towels and handkerchiefs of an afflicted individual.If there is a chemical that accidentally get into your eyes, immediately flush it with water.Do not rub the eyes with your hands especially if you are not sure if your hands are clean.
Patients with pinkeye heal normally after five (5) to seven (7) days.But if it is viral or the pinkeye case becomes worse, it lasts from three (3) to four (4) weeks.
If pinkeye is caused by allergies or pollution, this will last longer if the patient is not moved from the place where the cause is found.
Patients can easily be treated even with a home treatment.The following are suggested:
.You can put a cold or lukewarm towel over the affected eyes to ease the irritable feeling.
.From time to time, remove the accumulated dirt around the eyes with a cotton ball or a washcloth.
.Avoid putting on your contact lenses, and applying eye make up until the sickness is treated.
.If a specialist advises to use eye drops, follow the instructions.After putting on a few drops, close the eyes to let it spread inside them.
It is risky to apply antibiotics around the eyes especially for children.
.Ensure that the medication used is ophthalmic (for the eyes) and not otic (for the ears).
.After application of medication, wash hands thoroughly so that the bacteria that caused it will not spread inside your home.
When are you going to bring a severe case of pinkeye to the doctor?This is when you observe the following symptoms:
Pain in the eye.
.Poor vision.
.The eye becomes sensitive to light.
.Greenish yellow discharge that stays.
.If pinkeye lasts more than seven (7) days.

Article by Peter Filinovich
Eyesight is a valuable gift from God to us. The person who is blind well knows the value of eyesight. Eyesight and breathing are of equivalent importance. We are in a position to appreciate this colorful world due to eyesight only. There are some common problems related to our eyesight.
1. Myopia or short sightedness – This problem is caused due to elongated shape of our eyeball. Person suffering from the problem of myopia are unable to see distant objects clearly. The common symptom of myopia is headache. The solution to the problem of myopia is contact lenses, Lasik surgery and eye glasses.
2. Hyperopia or farsightedness – The problem of hyperopia is caused due to the shorter shape of eyeball. People suffering from hyperopia are unable to see the nearer objects more clearly but they can see the distant objects more clearly. The treatments of hyperopia are Lasik surgery, contact lenses and eye glasses.
3. Astigmatism – In this problem the shape of the eye ball becomes oblong instead of spherical. The common symptoms of astigmatism are blurry vision and headaches. The treatments to this problem are refractive surgery, eye glasses and toric lenses.
4. Presbyopia this problem affects the people at the age of 40. In this problem people may suffer from eye weakness resulting in unclear vision. Solutions to this problem are reading glasses and bifocal lenses.
The causes of eyesight problem are deficiency of Vitamin A, C, aging, heredity, strokes, fatigue, drying of eyes, certain diseases like diabetes, brain tumors, malnutrition, internal eye bleeding, overexposure to sunlight, radiation, etc, due to some medications like antihistamines, anticholinergics, malaria pills, certain blood pressure pills etc.

General Information: Your Eyes and Vision
Eyes occupy the most space among the five sense organs of our body, we must take care. Big and beautiful eyes enhance beauty to a large extent. There are two kinds of beautiful eyes. One is related to the overall health of a person and the second is related to makeup. Healthy eyes and vision care are directly related to health in general.
Sometimes the weakness of the eyes is hereditary. Never hesitate to use glasses in case of weak eyesight. A show with a nice frame that matches with the face goes far in enhancing the beauty of a person, rather than diminishing it. If the loss of vitamins A and D is the cause of poor vision and apart from medical treatment, you should take the milk, cheese, eggs and green vegetables as they contain vitamins A and D. For eye diseases, such as conjunctivitis or watery, you should see an ophthalmologist (eye specialist).
Diabetes and eye
Hyperglycemia and hypertension (high blood pressure) can damage the thin blood vessels that lead to the retina.
If you suffer from diabetes type 1 or type 2, it is important to tell your eye specialist and undergo an annual eye exam to detect any sign of a complication called diabetic retinopathy. This disease can be painless with no symptoms until it becomes serious, but it can be controlled and treated, and its evolution can be slowed significantly.
Loss of Vision
Many people over 65 years experiencing some loss of vision that is not related to the usual problems associated with age as presbyopia or cataracts. For example, glaucoma can cause permanent loss of peripheral vision, and macular degeneration can block a portion of your field of vision in one eye he or both eyes.
This disorder eye sight is known as low vision, a condition that can be corrected with eyeglasses, contact lenses or surgery.
Some precautions to make beautiful eyes
• Certain precautions must be taken to keep the eyes healthy and beautiful.
• You must see that there is enough light when reading, writing or sewing.
• You should wash your eyes with eye wash once or twice a week.
• Rose water or water Triphala is very beneficial for the eyes. It reduces the brightness. Even boric powder can be used for washing eyes.
• Too bright light is also damaging. You should use sunglasses (goggles) whenever you’re dealing with sunshine.
• After a hard day to lie down, close your eyes and on their place of cotton wool swabs soaked in ice water.
Drooping Eye Treatment
Your eyes will require about eight hours of rest during a day, if they feel falling (or heavy). Smoking makes your eyes yellow. Eyes turn red if good rest is not given to them. For treatment of drooping eyes, lie down on the bed and place a piece of cucumber (cut into round shape) on both eyes. But before that, all eye makeup should be removed. Eyes need rest during the day also, with the exception of the night. Each time your eyes feel tired, close them and place your palms on them. You will see the dark figures and some hazy blur.
Some simple exercises to more beautiful eyes
• Glitter lashes are an exercise machine. Close your eyes tightly. Then try to open as wide as possible. Repeat the process ten times. During the year that the flicker of the eyelashes, eyebrows should be static.
• Eyeballs should be rotated twenty times to twenty times and left to right. Lids must remain closed during the rotation.
• Flicker both eyes simultaneously and quickly. Repeat after the glittering closing the eyes for some time. Repeat this process ten times. Eyeballs get fat doing this exercise.
• Look in the mirror for five minutes to meet your eyes with the eyes of your reflection in the mirror.
• Mark some distant object. Then look at an object closer to you. Again the object in the distance and again to be closer to two minutes. Do this exercise for ten minutes.

The Top Five Tips for Protecting your Eyes and Vision
Article by TL Kleban
Losing your eyesight isn’t just something only old people need to worry about. Our eyesight is probably the most valuable of our senses. Do you think you can go the rest of your life without seeing a sunrise or a baby’s smile? It then should come as no surprise that most of us are more fearful of losing our eyesight than any of the other senses.
For nearly everyone on this planet, the lifestyle choices they make today directly affect their vision later on in life. All it takes is just a few minor and easy changes in your daily routine. Stop and take the time to begin a few healthy habits. You’ll quickly begin lowering your risk of harmful eye conditions like cataracts and age-related macular degeneration. Here are five ways for you to to protect your eyesight for the future and keep your eyes healthy as you age:
Protect your eyes – Did you know that by wearing sunglasses you can reduce your eyes exposure to eye-damaging ultraviolet? These are harmful rays are what causes the development of cataracts and the gradual deterioration of light sensitive cells in the macula, ultimately leading to the loss of vision. Try to buy sunglasses that come with 99 to 100 percent UV protection. Stick to yellow or amber lenses as well since they work best at filtering out harmful blue light. Lose the cigarettes – Recently, eye doctors discovered that people who smoke are up to four times more likely to develop vision problems than nonsmokers. They are also twice as likely to develop cataracts later on in life. Eat your fruits and vegetables – Vision experts found that lutein and zeaxanthin found in fruits and vegetables, like spinach and orange bell peppers, reduce the risk of eye problems by more than a third. These antioxidants work by absorbing those harmful UV rays in your eyes as well as improve their overall health in maintaining optimal eye function. Watch your weight – Being obese or overweight causes hypertension, high cholesterol, and inflammation. All three of these problems slows down the flow of blood to your eyes increasing the risk cataract development. Take out the contacts – One of the worst things you can do to your eyes is to sleep in contacts or keep them in from weeks at a time without removing them. Even the continued use of daily contacts for longer than they were intended can cause harm to your eyes. The reason is that things like dirt and bacteria are trapped between the contact and your eye, causing irritation and even infection. It’s ok to sleep in your contacts if they were designed for that and under a doctor’s recommendation but otherwise no. The eyes require both oxygen and rest and they get neither when you sleep in them.
How Acquired Brain Injury Can Disrupt Vision
What is Acquired Brain Injury?
An acquired brain injury is brain impairment after the birth of an individual in contrast to brain damage that is present at birth. Acquired brain injury can be caused by the following:
- Physical trauma such as road traffic accidents
- Malignancies such as brain tumors
- Infections
- Cerebral vascular accidents (strokes)
- Substance abuse
- Hypoxia (inadequate oxygen supply)
- Poisoning such as lead or arsenic poisoning
- Encephalopathy (diseases and metabolic derangements of the brain and other parts of the body that damage the brain)
Ways Acquired Brain Injury Can Disrupt Vision
Vision is often affected in acquired brain injury because the visual pathway is essentially an extension of the brain and also because of the pathway’s delicate nature. The visual pathway begins from the eyes which transmit what they see to the optic nerves. These nerves carry the images from the eyes, exit the eye sockets and enter the brain through spaces in the bones of the skull. The nerves then run through the brain where they are predisposed to any damage that may happen in the brain. The optic nerves end in the visual cortex of the brain where the images from the eyes are received and processed. Therefore, vision loss may result from damage to the eyes, damage to the nerve(s) supplying the eyes and/or damage to the part of the brain that processes vision.
The following are ways through which acquired brain injury causes vision impairment:
1. Damage to the eye: Trauma can easily destroy the eyeball and/or cause detachment of the retina from the eye.
Optic nerve severance and damage to nerves that control eye movement: Physical trauma such as skull fractures (especially to the bones of the skull through which the optic nerve passes) can cut the optic nerve. The result is that the affected eye cannot send what it sees to the brain and this manifests as vision loss in that eye. Damage to the nerves that control the movement of the eyes: the oculomotor, trochlear and abducent nerves can lead to diplopia (double vision) and other vision disorders.
Brain tumors compressing the optic nerve: Along the visual pathway, the optic nerves from both eyes meet at a point called the optic chiasma where they share nerve fibers with each other. This point is located just above the pituitary gland and tumors of this gland compress the nerves leading to a progressive loss of vision as the tumors enlarge. Tumors of any other part of the brain can compress the optic nerves along their course also causing vision loss. Brain tumors that affect other nerves that control the eye also cause vision impairment.
Infections: Infection usually results in cell death with pooling of pus called abscesses. If this occurs along the path of the optic nerves or at the visual cortex, vision may be affected. Other nerves which are involved in the coordination of eye movement may also be damaged and lead to vision disruption. Infections such as syphilis and herpes zoster also directly damage the optic nerve.
Cerebral Vascular Accidents (Strokes): Strokes may be
- Ischemic in which blood supply to the brain is severely reduced along with the nutrients and oxygen contained in the blood.
- Hemorrhagic in which a damaged blood vessel leads to blood loss and accumulation inside the brain.
A stroke may affect the visual cortex of the brain damaging it. An ischemic type of stroke called Ischemic Optic Neuropathy affects the optic nerve and may damage it.
6. Hypoxia: Hypoxia is a situation of inadequate oxygen supply to the body which the brain is particularly sensitive to. Brain cells die within minutes of lack of oxygen and if the visual cortex is injured, vision loss occurs. The optic nerve may also suffer from this.
7. Substance Abuse: Drug abuse may cause vision loss in several ways that ultimately destroy the visual cortex of the brain or the optic nerve. The following are examples of ways through which substance abuse may cause vision disruption:
- Cocaine use may cause recurring microscopic cerebral vascular accidents.
- The inhalation of heroin and other inhalants may destroy large portions the brain.
- Methyl-alcohol abuse destroys the optic nerve.
8. Encephalopathy: Disease in other organs may also lead to brain injury and. Examples of encephalopathy due to disease in other organs include:
- Uremic encephalopathy which occurs in kidney disease due to a high level of circulating toxins which should have been excreted by the kidneys
- Hepatic encephalopathy in which the liver is diseased and cannot carry out its normal function of detoxifying the body.

Looking and Acting: Vision and eye movements in natural behaviour
The cooperative action of different regions of our brains gives us an amazing capacity to perform activities as diverse as playing the piano and hitting a tennis ball. Somehow, without conscious effort, our eyes find the information we need to operate successfully in the world around us. The development of head-mounted eye trackers over recent years has made it possible to record where we look during different active tasks, and so work out what information our eyes supply to the brain systems that control our limbs. We are now in a position to explore the strategies that the eye movement system uses in the initiation and guidance of action.Looking and Acting examines a wide range of visually guided behaviour, from sedentary tasks like reading and drawing, to dynamic activities such as driving and playing cricket. A central theme is that the eye movement system has its own knowledge about where to find the most appropriate information for guiding action - information not usually available to conscious scrutiny. Thus each type of action has its own specific repertoire of linked eye movements, acquired in parallel with the motor skills themselves. Starting with a brief background to eye movement studies, the book then reviews a range of observations and analyses of different activities. It ends with discussions of the nature of visual representation, the neurophysiology of the systems involved, and the roles of attention and learning.
Opening a field in eye movement research, this fascinating book will be of great interest to all vision scientists (psychologists, physiologists, ophthalmologists) whether at professional, graduate, or advanced undergraduate levels. It will also be of value to musicians, artists, sports scientists, and transport engineers, and indeed anyone intrigued by the way we sample the visual world.
