There is a layer of aqueous film in our eyes, which is actually a crucial safeguard for our ocular health. This layer of film is known as the tear film. It covers the surface of the cornea, responsible for maintaining ocular moisture and providing protection against external substances from entering the eye. The tear film consists of three layers, including the epithelial cells, anterior chamber, and stroma. However, sometimes this layer of aqueous film may become unstable or rupture, leading to ocular discomfort, pain, redness, and swelling.
1. Ocular infections: When bacteria, viruses, or other pathogens invade, they can disrupt the stability of the tear film, triggering an inflammatory response. During this time, the eyes may exhibit redness, swelling, and pain. Prompt medical attention is crucial, and doctors will administer corresponding treatment based on the type of infection.
2. Prolonged ocular fatigue: In modern life, we often stare at computer screens or mobile phones for extended periods, which can lead to tension in the ocular muscles and impair the function of the tear film. Appropriate breaks and ocular exercises, such as gazing into the distance for a few minutes every hour, can effectively alleviate ocular fatigue.
3. Dry eye syndrome: This is a common issue caused by insufficient tear secretion or poor tear quality, making the eyes feel dry and uncomfortable. Using artificial tears or moisturizing eyedrops can alleviate symptoms, but long-term symptoms require professional assessment and treatment by a doctor.
4. Other diseases: Allergic conjunctivitis, immune system abnormalities, or other systemic diseases may also affect the stability of the tear film. If ocular discomfort persists, it is best to seek the help of an ophthalmologist for a comprehensive examination and targeted treatment. Maintaining the health of the tear film is crucial for overall ocular health. If you notice any ocular discomfort, seeking medical attention promptly is advisable. Ophthalmologists will conduct a detailed examination to help you develop a suitable treatment plan, restoring ocular comfort and health. In daily life, we can also protect our eyes by using them reasonably, resting adequately, and maintaining good living habits.
