Spring is the most beautiful season of the year and the best time to travel to the greenery. When you are intoxicated by the bright spring light of nature, have you ever thought about how to protect the windows of our hearts? Spring is the season when many plants are in bloom and people are willing to go out in this beautiful season, some people with allergies should pay attention. Maybe a trip will make your eyes red and itchy, and you will keep on weeping. Why is this? This is because of the increase in plant pollen and plant-based particles in the air, and the recurrence of allergic conjunctivitis and follicular conjunctivitis due to environmental allergens, which can lead to the above discomfort, and even in some cases of heavy reactions, severe skin roughness and flushing, itching and flaking. This is the time when you need to go to the hospital ophthalmology department for an eye examination and your symptoms should be significantly relieved after the use of anti-allergy eye medication. Spring is also the season when viral keratitis is likely to occur. The main symptom is damage to the cornea, which manifests as photophobia, burning, and tearing. Flushing of the skin around the eyes and papules may also occur. The virus can also cause diseases such as conjunctivitis, retina and optic neuritis. Spring is also the season when many women love beauty and they choose to wear contact lenses, especially now with the emergence of decorative corneal contact lenses such as contacts, which are sought after by women who love beauty. Wearing corneal contact lenses for long periods of time tends to increase eye discomfort, such as dryness, itching, tearing, and even pain. This is the time when you need the help of an eye doctor to check for the possibility of infection. In the spring, many areas experience dusty weather, making the weather dry and many people experience dry eyes and astringent eyes. This can be dry eyes, especially for people over the age of 50. Often, your eyes feel sticky and dry. A visit to the hospital to purchase some artificial tears will help. More importantly, it is important to strengthen the transient eyes and moisten the cornea. After working continuously at close range for a period of time, it is important to give your eyes a rest. You can do eye exercises or, more simply, look into the distance to relieve eye fatigue, which will also help dry eyes. According to Chinese medicine, “spring is wood”, and the liver and gallbladder are on the inside and open to the eyes. Therefore, spring is the best season to protect the eyes. In spring, when the flowers bloom, we should take good care of our eyes and strengthen the protection of our eyes.
