Recently the number of patients with dry eye syndrome has increased. Such patients were rare ten years. When I was majoring in medicine at the college, such symtoms were not treated with significance. However, I see those patients who suffer from dry eyes very often and I figure that it has a lot to do with air pollution. Your eyes can no longer maintain good conditions for your eyes because you are exposed to bad weather, air pollution and your mobile environment as well.

 

DES is a condition caused by a lack of moisture on the surface of the eye. The cause of the dryness is the heat that dissipates moisture from the eye. The heat evaporates the tear that lubricates the oscular surface. When there are not enough tears, the eye becomes dry and cause redness and feeling gritty. In worsened state, the eyestrain becomes constant whether the eyes are opened or closed. Sleep may bring temporary relief to the condition, but the eye fatigue returns soon. The retina constitutes over 100 million light detective cells and 1 million optic nerve cells clustered, processing the most amount of information per area in the body, consequently, it generates the most amount of heat.

 

The heat can be taken away by blood circulation, however, that is not enough in most cases. To cope with this, the eyes are attached to a customized cooling device for the eyes. The nasal cavity and paranasal sinuses function as an anti-overheating device for the eyes. If eye strain is present, caused by DES, then it must observe whether there is sufficient ventilation in the cavity and sinuses. Once clear ventilation is restored in those areas, even serious cases of DES experience significant improvement.

 

Clinical experience reveals preadolescent children who suffer from sinusitis rarely complain of DES. It suggests the blood circulation of children is without impedance. However, when the demand on the eyes becomes increased (like when students prepare for college entrance exam), people start to experience eye strain and dryness. This is due by the heat generated by the eyes exceeded the amount of heat that blood circulation able to dissipate.

 

The cause of DES has been explained as lack of fluid supplied to the cornea or change in the constituents of tear, however, it would be more appropriate to define it as evaporation of tear caused by excessive heat in the retina.

 

 

The body's anatomical structure is designed in such a way to effectively diffuse the heat generated from the eyes, in taking each breath. Therefore, frequent blood-shot eyes warrants attention. The increased frequency of bloodshot eyes may coincide with partially blocked paranasal sinuses. At this stage, the body can cope with it by inducing more fluid by blinking the eyes more often. Accordingly, frequent blinking can be a sign of early DES. This, however, most people do not recognize themselves since it is carried out by an autonomic nervous system.

 

 In the case of constricted paranasal sinuses, the efficiency in convective heat transfer decreases relatively, causing strenuous blinking. In other words, the muscles around the eyelids are also flexing their muscles to blink. This is not serious enough to seek medical attention. Rolling the eyes while closed can relieve the eye strain easily at this point.
