Technological advancements has also given rise to new medical conditions, and computer vision syndrome is one of these. It is associated with prolonged staring at a computer screen. While it is not a disease as such, it does highlight the importance of educating people about using a computer appropriately in terms of eyestrain, hours of use and good posture while staring at a screen. Unfortunately this is not included as part of computer learning programs. Computer vision syndrome is gradually becoming a more widely known condition. Despite its name, computer vision syndrome does not only cause visual symptoms.

The discharge of eye mucus is a normal physiological process. The mucuous membranes of the conjunctiva secretes this mucus in small quantities. It mixes with tears an oily substance (meibum) and dead skin cells to become thick and watery. However, when exposed to air for long periods it may harden and form a crust. This is more prominent when awaking after sleep. For this reasons, it is often referred to as sleep dust. Hardened eye mucus is also known as eye gunk or eye boogers but the more correct medical term is rheum.
Whether it is a sagging upper eyelid or drooping and puffy lower lids, we would all like to restore our eyelids to their original youthful glory. The fact is that these age-related changes of the eyelids alters the appearance of the eyes and causes us to look older than we would like to appear.
Fortunately cosmetic surgery can easily correct these changes and restore youthful eyes within hours. Understanding what eyelid lift surgery entails as well as the risks and outcomes can help you make an informed decision before you go under the knife and fork out substantial amounts of money for the procedure.
Injuries from chemicals are a common part of life. It is not only from strong industrial chemicals but even from everyday household items and certain spices. Chemical injuries can affect any part of the surface of the body with which it comes into contact. However, it is usually worse when it makes contact with the eye since it is living tissue that lacks the hard protein layer of the outer skin apart from the protection offered by the eyelids. A quick remedy is often needed until professional medical attention can be sought.
It may not be aesthetically appealing but bags under the eyes are usually harmless. It is a result of swelling and sagging of the lower eyelids and sometimes there are dark circles around the eyes as well. Most of us experience bags under the eyes every now and then – be it after several days of very little sleep, after long bouts of crying, sometimes with hormonal changes in women and occasionally due to changes in weather. For some people it can be a long lasting problem especially if it occurs with allergies or due to heredity factors. Remedying bags under the eyes may sometimes be as simple as doing nothing. At other times these bags are permanent and can only be corrected with surgery.
Visible bruising can occur anywhere on the body even though there is no break in the skin. Trauma may lead to damage deeper down in the skin which is visible from the outside. This is what happens with a black eye, also referred to as a blue eye or a shiner. Be it a punch, being struck by a fast moving ball or some other trauma to the eye area, a black eye is unsightly but it is rarely ever serious. The swelling and darkness may be ghastly but within a week or two it can clear up entirely.
Conjunctivitis, or pinkeye as it is commonly known, is a condition of the outer part of the eye that causes pronounced redness, itching and tearing. Although pinkeye looks very serious and somewhat scary, it is actually a mild condition that rarely leads to any complications. Pinkeye can affect both adults and children but most of know about the outbreaks of pinkeye in schools. Therefore it is often thought of more as a condition among children. Indeed children are more prone to outbreaks, and for good reason – they do not practice the same preventative measures that adults would when pinkeye is doing its rounds.
The appearance of human eyes differs significantly among people and it is not just the shape and size. The eyelids and orbit also contribute to the overall look of the eyes. Some people have a natural “sleepy” appearance of the eyes and it is largely due to the the eyelids, particularly the upper eyelid. However, even the brightest doe-eyed person may have sleepy eyes at times especially when they are tired. This change in the normal appearance of a person’s eyes usually signals sleepiness, hence the term “sleepy eyes”. It is mainly due to the eyelids drooping as well as puffiness around the eyes, ‘bags’ under the eyes and eye redness.
Many of us put more value to our sense of vision than to other senses like smell or taste. And the first sign of a visual disturbance triggers anxiety and stress. But vision problems are not uncommon in the modern world. Refractive errors like myopia (shortsightedness) are commonplace these days and can be easily corrected. It is unlikely to lead to serious disturbances in vision even in the long term. However, not every visual disorder is as easily treated. Sometimes blurred vision is an early symptom of a more serious eye disorder that can eventually lead to blindness.
Bell’s palsy is a sudden paralysis of one side of the face that is often mistaken for a stroke. It causes anxiety and panic for both the patient and their loved ones, but unlike a stroke the consequences of Bell’s palsy is almost never fatal. Most cases of Bell’s palsy recovers completely and even without treatment. Symptoms typically ease within a few weeks from the time it starts but sometimes can take as much as 6 months to resolve completely. In some rare cases Bell’s palsy may recur but for the vast majority of patients they never experience it again.
Visual acuity is our ability to see clearly. As humans our eyesight may not be as impressive as some other mammals but nevertheless it serves us sufficiently to conduct our daily activities. But eyesight problems have become commonplace in the modern world for a number of different reasons. It is lifestyle-related, due to genetics and even associated with some of the chronic diseases that have become common these days. The common causes of bad eyesight can vary. It may be a problem with the way light is bent, the amount of light that can enter the eye or a deterioration of the light-sensitive eye tissue.
Our body can only sustain activity for a certain period of time in a day before it needs to “recharge” with a restful sleep. One of the ways that you know that is time to rest is when the eyelids becoming “heavy”. This is a common way to describe the difficulty in keeping the eyelids open. The weight of your eyelids do not actually change. Instead the eyelid muscles become tired and experience difficulty in keeping the lids opened. However, there are times when you have no choice but to ignore this signal or continue to have heaviness of the eyelids despite having slept adequately.
Eyestrain or eye fatigue has become common place in everyday life for many of us. Most of the time it is nothing more than an annoyance but for some people it can be quite debilitating. Fortunately eyestrain does not lead to any permanent complications but the symptoms may recur on such a frequent basis that it affects a person’s life and even their ability to work. Eyestrain is often a result of ignorance rather than just being overworked. A few simple measures that will take only a few minutes can prevent eyestrain, even amidst a busy work schedule.
Fungal keratitis is an infection of the cornea caused by a fungus. Although keratitis (corneal inflammation) can occur for several reasons, a fungus is one of the more common causes of infectious keratitis. It can lead to severe damage of the eye and blindness if not diagnosed early or left untreated for long periods of time. Fungal keratitis can affect any person but it is more commonly seen among contact lens users. It has also become a significant indicator of HIV infection, particularly in Africa. Although the elderly and patients who are immunocompromised are more likely to be affected, fungal keratitis can also occur in the immunocompetent and young individuals.
Hyphema is a condition where there is a collection of blood inside the front of the eye (anterior chamber). The accumulation of the blood within the anterior chamber is usually visible. It occurs with injury to the eye, during or after surgery and in rare cases it may arise as a consequence of certain diseases. Depending on the extent of the bleeding, a hyphema may block the vision either partially or completely. The sight of blood in the front of the eye is often the most distressing symptom, along with the pain. However, the lack of visible blood does not mean that there is no bleeding as is the case with a microhyphema.
The eyes are made up of very delicate tissue, some of which are exposed to the environment. Although the thin outer lining known as the conjunctiva and the eyelids protect the eye tissue, the eyes are more prone to various forms of injury more so than any other part of the body. Naturally when one is faced with an injury to the face, it is instinct to first cover the eyes.
Being such sensitive parts of the body, it is normal for discomfort to arise in the eyes even with a little strain or slight injury. One of the common sensations that a person experiences in the eye is a burning feeling, which can sometimes be severe enough to be painful. At other times there may be the sensation of heat in the eyes without actually feeling like a burn. Both these sensations, burning and heat, can be due to a number of causes some of which are minor while others can be very serious and even permanently damage the eye. Other types of discomfort may include an aching feeling, soreness or grittiness in the eyes.
