Dry eye syndrome is a common problem of many people today, especially the officers who often use computer. Dry eye is not too dangerous but it can cause tired, red eye and irritated eye reducing performance. In the most serious cases, the patient may gradually lose eyesight. When dry eyes, the patient usually has the feeling of burning sensation, ache, fatigue and heavy. Common symptoms are blurred vision after blinking, shedding tears and rheum on the edge of the eyelids.
Dry eye is caused by imbalance of the ability to produce tears. According to experts, dry eye causes are:
The amount of tears secreted is not enough
Tears from gland in and around the eyelids help to protect the eyes. This ability will decrease with an increase in age, or with people who have eye diseases. Besides, wind, weather and the polluted environment also can cause dry eye. In particular, those who regularly stare at a computer screen for many hours a day will speed up the evaporation of tears, leading to dry eyes.
The quality of tears is not good
The tear film is made up of three layers: an oil layer, a water layer and a mucin layer. These three layers work together to protect the eyeball from external factors. Mucin layer helps the tears stick to the surface of the eye, the oil layer reduce evaporation of our natural tears. Dry eye is caused by tear evaporation very quickly or tears not sticking to the surface of the eye.
These three layers are imbalance, causing the evaporation of tears and dry eye. Besides, some diseases can cause disturbances in the mucin layer and oil layer, that will also make the eyes susceptible to dryness. Diseases such as rosacea can also prevent mucin layer from producing water.
Have habit of blinking slowly and evenly (about 12-18 times per minute) to help stick tears to the surface of the eye and moisturize the cornea.
Limit your eyes to contact directly with dust and light. You should wear glasses when go out to protect the eyes from harmful agents of the environment. Avoid hairdryer, fan and air-conditioner blowing the air directly into your eyes.
Do not stay up late, get enough sleep 7-8 hours per day, helping the eyes have the best time to rest.
Do not smoke and avoid exposuring to secondhand smoke.
Have a reasonable balanced diet. Provide regularly food rich in Omega-3 (found in fish) and Beta-Carotene (found in yellow and red vegetables). You should boost antioxidant for good eyes.
