How to protect eyes from harmful agents

According to ophthalmologists, eye diseases are caused by many factors. If you do not know how to care for and treat them properly, your ability to see will become increasingly limited.

Here are some causes of eye diseases and medical experts' suggestions for better eye care.

Causes of eye diseases

Clinical studies show that eye diseases can occur at any age, but the risk of disease is often higher in older people, especially those aged 40 and over.

After this age, the body parts will gradually degenerate, then the eyes will show signs of blurred vision, fatigue, pain, and dry eyes. This is the result of a disorder in the protein synthesis process of the lens and retina, leading to opacity of the lens and degeneration of the retina.

Regular eye exams are necessary to detect eye diseases.

Nowadays, due to many factors, signs of aging appear earlier and earlier. Many people, even though they are only 40 years old, have poor eyesight like those in their 50s and 60s. Pollution leads to a weakened ozone layer, causing ultraviolet rays in sunlight to directly affect the eye's "lenses" and retina, changing the structure and protein composition of the lens, leading to cataracts.

Not to mention, dust, toxic chemicals, and polluted water sources when in frequent contact with the eyes will accumulate many toxic substances, thereby damaging the endothelial cells of the retina, causing damage to visual cells and impairing vision.

According to Associate Professor, Doctor Ha Huy Tai - Hanoi Eye Hospital 2, frequent exposure to electronic devices is also one of the causes affecting the eyes.

Many studies around the world have also shown that screen devices such as computers, phones, televisions, fluorescent lights, LED lights and sunlight all contain harmful blue light. This is a type of light with short wavelengths but high energy, so it can penetrate deep into the eyes and have a regular impact, causing damage to the retina, especially retinal pigment epithelial cells.

Data from the World Health Organization also shows that exposure to blue light for more than 3 hours a day increases the risk of vision loss by 90%.

Protect eyes from harmful agents

According to Associate Professor, Doctor Ha Huy Tai, there are many measures to prevent eye diseases and each age group will have its own notes.

Specifically, for students, one of the essential things to protect the eyes is to work and study in moderation and give the eyes time to rest.

Students must balance their study time to protect their eyes.

The study area must have enough light. Light that is too strong or too dim will tire children's eyes. They must sit in the correct posture when studying. Parents should also control the amount of time they spend studying and using technology devices to avoid their children's eyes from working too hard for too long.

For students with refractive errors, in addition to the above, they need to wear glasses and wear glasses with the right prescription so that their eyes can see clearly and do not have to adjust, and have their eyes checked every 6 months or at the beginning of each semester to monitor the progression of myopia.

For workers, Associate Professor, Doctor Tai said that it is necessary to avoid working too long on the computer, which will cause eye fatigue and eventually lead to eye problems. You can relax your eyes after each working hour by closing your eyes, or blinking several times when working in dusty and bright places, and using eye drops when necessary.

In addition, regular eye examinations every 6 months are the best way to detect eye diseases early. A reasonable diet and lifestyle, providing foods rich in vitamins, especially vitamins A and E, help fight oxidation, reduce the risk of cataracts or provide Lutein to help protect the retina.
