How to protect your eyes from harmful agents.

According to ophthalmologists, eye diseases are caused by many factors. Without proper care and treatment, vision will gradually deteriorate.

Below are some causes of eye diseases and suggestions from healthcare professionals for better eye care.

Causes of eye diseases

Clinical studies show that eye diseases can occur at any age, but the risk is generally higher in older adults, especially those 40 years and older.

After this age, the body's organs will gradually degenerate, and the eyes will show signs of blurred vision, fatigue, pain, and dryness. This is a consequence of a disruption in the protein synthesis process of the lens and retina, leading to lens opacity and retinal degeneration.

Regular eye exams are essential for detecting eye diseases.

Nowadays, due to various contributing factors, signs of aging are appearing earlier and earlier. Many people, even at just 40 years old, experience vision deterioration similar to that of someone in their 50s or 60s. Pollution leads to ozone depletion, causing ultraviolet rays from sunlight to directly affect the eye's "lenses" and retina, altering the structure and protein composition of the lens, resulting in cataracts.

Furthermore, smoke, dust, toxic chemicals, and polluted water, when frequently exposed to the eyes, will accumulate many harmful 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.

Numerous studies worldwide have also shown that screen devices such as computers, phones, televisions, as well as fluorescent lights, LED lights, and sunlight, all contain harmful blue light. This type of light has a short wavelength but carries high energy, so it can penetrate deep into the eye and, with constant impact, cause damage to the retina, especially the retinal pigment epithelial cells.

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

Protect your eyes from harmful agents.

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

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

Students must balance their study time to protect their eyesight.

The study environment needs to have adequate lighting. Both excessively bright and dim lighting can tire a child's eyes. Proper posture is essential while studying, and parents should also monitor study time and screen time to avoid overworking the child's eyes for extended periods.

For students with refractive errors, in addition to the above, they need to wear glasses with the correct prescription to see clearly and avoid eye strain. They should also have their eyes checked every 6 months or at the beginning of each semester to monitor the progression of myopia.

For workers, Associate Professor and Doctor Tài advises avoiding working for too long in front of a computer, as this can cause eye strain and eventually lead to eye problems. They can relax their eyes after every hour of work by closing their eyes or blinking frequently when working in dusty or brightly lit environments, and use eye drops when necessary.

In addition, regular eye checkups every six months are the best way to detect eye diseases early. A healthy diet and lifestyle, including foods rich in vitamins, especially vitamin A and vitamin E, help fight oxidation and reduce the risk of cataracts, while lutein helps protect the retina.
