The red color appears in the eyes as a reaction to the arrival of the stimulus in the form of dilated blood vessels. So, irritation is actually the body's natural attempt to reject substances that interfere with the eye.
On average, it's due to stimulation, but causes and severities of red eyes can't be flat beaten. All mustn't boil down to irritation. For example, when you wake up in the morning, sometimes, your eyes suddenly look red.
Why is it red? The explanation is about this. When on duty, the eye requires adequate oxygen supply outside and inside the body. When you're sleeping, the eye doesn't get enough oxygen from the outside while still has a supply of the body.
In other words, the amount of oxygen that goes is less.
To avoid oxygen deficiency, eye anticipates by dilating blood vessels. By dilating blood vessels, oxygen supply can be fulfilled, roughly the same as literating. So, when you wake up, eyes look red.
If the eyes also feel tired and sore, try to remember carefully whether in the evening, you're working too hard. If the answer is a yes, there's nothing to worry. With enough rest, the eyes will be back to normal.
Conversely, if the red eyes are followed by pain that lasts up to three days in a row, you'd immediately consult a doctor. Prior to that, to relieve sore, eyes can be given drops or ointment containing antibiotics.
Symptom of deficiency of oxygen potentially turning into irritation, one of them, is due to using contact lens constantly. Physically, your eyeballs are actually hollow or porous like skin. The continuous use of contact lenses can make eyes not breathe.
Thus, the suggestion to removing contact lenses occasionally is beneficial for the care and hygiene, also letting eyeballs take breath freely. You can also examine all contact lenses whether they're still intact and not dry to avoid hurt.
There's also red eye flickering in the long term. Such symptoms are usually caused by allergies that come and go, and last a long time. Sometimes, it's accompanied by itching if the eyes communicate with dust, wind, or other triggers.
To cure this recurrent red eyes, you'd able to keep track of factors of allergy triggers in your eyes.
Eyes with allergies usually have itches, red, sometimes small rashes. You'd take preventive drops or antihistamines to relieve symptoms.
If you're with tuberculosis, measles, diphtheria, and worms, you can also be stricken with symptoms of red eye. For this one, it's certainly not gonna recover granted only with antibiotics. You must cure the master disease first that cause the root of red eye.
For example, if red eye turns to be a part of measles or worms, yes, they'd be first eliminated.
The risk of eye irritation are more likely to attack if you work in the open field. There're many enemies of the eye, such as dust, vehicle fumes, or chemical liquid or gas, ready to stimulating if you're off guard.
However, don't worry. There're many ways to anticipating. One of them, the most practical, is wearing safety glasses, especially in places suspected to contain a lot of pollution.
What if you like swimming? Don't eyes turn red after a swim? Symptoms of this one shouldn't be worried. Eyes will recover by themselves. Red eyes are not due to conceded bacteria but because of chlorine in swimming pool water.
Chlorine actually contains an antiseptic that can protect the eyes from harmful substances.
The human eye is already equipped with excellent protection system. Protective fortresses in the sense of sight are laminated from nature. The outermost layer is coordinated by the eyelashes and eyebrows while the inside defense is on blink reflex and tear that comes in a certainly unparalleled chemical composition.
With that strong fortress, irritation of the eyes can actually disappear on its own, alias naturally healed. Except you're very sensitive, recovery power may take longer, sometimes it needs to treat or take to the eye doctor.
The use of eye drops is actually fine, but you'd use them for a certain time, not continuous or protracted. Eye drops, for example, are required at the dry time, or tear production lacks due to aging and glaucoma, or when your eyes are exposed to infection or allergy.
Because it's a breeze at roadside stalls, sometimes, eye drop is regarded as an everyday food. Going everywhere, you always equip yourself with eye drops. Once your eyes are red, you immediately drop it twice or thrice.
Irritation is missing without trace, but the scars caused by side effects can be more dangerous.
That's why, for serious reasons, the use of eye drops should be on medical advice because in the free market, it contains substances refining or shriveling eye vessels. If the blood vessels constrict, flow can be blocked.
It's very dangerous if you have glaucoma. If it's overused, glaucoma that originally hides can suddenly appear to befall your eyes.
While irritation is treated, also search what causes it. If the irritation is due to smoke, you'd quit smoking. It could also be because it doesn't fit in certain cosmetic products, such as powder or eye shadow. You can be sensitive to the chemical constituents in cosmetic products. If irritation occurs due to exposure to chemicals, immediately rinse with clean water as much as possible.
To clean the eyes, you don't need to use boric acid, enough with water, then immediately go to the doctor. If it's delayed, severe irritation could grow pterygium which could eventually cover the pupil of the eye and impair vision.
To scrape and remove it, it needs minor surgery, and of course, the cost ain't cheap. If it can still be prevented, why should you wait to enter the operating room?
