[alijen]

Eye diseases are increasingly common in modern life. In the age of technology, eyes are often exposed to electronic media or environmental pollution, causing eye diseases to increase.
The eyes are the most sensitive part of the human body, so without proper care, the eyes will easily get some diseases.
1. Eye allergies
Allergies are the most common eye disease. The causes of the disease are many, including direct sunlight (for sensitive eyes), air toxins, dust, perfume and even certain foods! When allergic, the eyes will become red and itchy.
2. Refractive error
According to research by Saigon Eye Hospital, refractive error is the most common cause of vision problems. Our eyes can see objects due to refraction in the eye, which occurs when light passes through the cornea and reaches the retina. Refractive errors occur due to the length of the eyeball, changes in the shape of the cornea or natural aging of the eye.
Nearsightedness, farsightedness, color blindness (test at the color blind test), and astigmatism are symptoms of refractive errors. Refractive errors are most common in people over 40 years old.
3. Macular degeneration
Age-related macular degeneration (ARMD or AMD) often occurs in men and women over the age of 50. AMD is a phenomenon in which the retina is damaged, leading to partial loss of vision, which can be severe. causes blindness. Macular degeneration has no symptoms.
Therefore, it is difficult to detect the disease. The disease is often only detected when it has progressed seriously. Therefore, to avoid the risk of vision loss due to macular degeneration, you should regularly visit the nearest eye hospital for an examination.
4. Cataracts
Cataract, also known as dry cataracts, is a phenomenon in which the lens in the eye becomes opaque, affecting vision. Cataracts often form in both eyes, but they never occur in both eyes at the same time. The main cause of cataracts is aging, and the disease can be easily removed by cataract surgery.
5. Glaucoma
In glaucoma, the optic nerve is damaged, thus affecting the eye's ability to see. Glaucoma is very common and is one of the main causes of permanent blindness. The main cause of glaucoma is an increase in the pressure of the fluid in the eye. Glaucoma can occur suddenly with few warning symptoms. Therefore, regularly have regular eye exams to avoid glaucoma.
