In recent years, with the popularity of electronic devices and the acceleration of information technology, more and more people have started paying attention to their eye health. According to surveys, there are over 200 million people worldwide suffering from myopia, and the incidence of dry eye disease is also on the rise. The severity of eye health problems cannot be ignored, therefore, protecting eye health has become increasingly important. Eye health self-test is a simple and practical method that can help us detect eye problems in a timely manner and take corresponding protective measures.
Myopia is a common refractive error of the eye, also known as nearsightedness or myopia. It is a visual impairment that makes it difficult for people to see distant objects clearly. Myopia is usually caused by an elongated eye axis, which prevents light from focusing on the retina, resulting in blurred vision. Myopia patients are often at high risk of other eye diseases, therefore, regular eye examinations are very important.
Dry eye, also known as keratoconjunctivitis sicca, is a condition where the eyes lack sufficient tears, have excessive evaporation or abnormal composition of tears, leading to eye discomfort and visual function impairment. Dry eye often affects both eyes, and patients typically experience symptoms such as eye fatigue, foreign body sensation, dryness, burning, and itching. In the early stages, it only mildly affects vision, but in severe cases, it can lead to corneal ulceration, perforation, or secondary infections, seriously affecting the patient's vision. Therefore, regular eye examinations are very important.
