What Causes Blurred Vision at Both Near and Far Distances?

Non-disease factors such as visual fatigue, or disease factors such as refractive errors and cataracts, may all contribute to this situation. To ascertain the cause, it is recommended to visit the ophthalmology department of a hospital as soon as possible for targeted treatment under the guidance of a doctor.

1. Non-disease factors: In modern life, excessive eye use for long periods is a common problem for many people. For example, reading or using electronic devices for long periods in poorly lit environments can lead to visual fatigue, causing blurred vision. The solution is actually quite simple: give your eyes appropriate rest and adjust your eye usage habits, such as taking a 10-minute break to look at distant scenery every 40 minutes of work, which are all good choices.

2. Refractive errors: Refractive errors refer to the inability of the eye's refractive system to accurately focus light on the retina, resulting in blurred vision. It is usually related to genetic and environmental factors, such as an excessively long anterior-posterior diameter of the eyeball or excessive corneal curvature. To address this issue, it is best to undergo a detailed vision examination at the ophthalmology department of a hospital, where doctors may recommend wearing glasses or other corrective measures.

3. Cataracts: Cataracts are caused by decreased transparency or color changes in the lens, leading to gradual vision loss and blurred vision as the condition progresses. In such cases, doctors may recommend using specific eyedrops to alleviate symptoms or, if necessary, surgical treatment.

Apart from the aforementioned causes, ocular diseases such as macular degeneration and glaucoma may also cause blurred vision. In daily life, maintaining a balanced diet with a focus on light foods and avoiding spicy and stimulating foods can help protect eye health. Additionally, pay attention to eye hygiene and avoid rubbing your eyes with your hands to prevent exacerbating discomfort. Eyes are the windows to the soul, and maintaining good vision is crucial for quality of life. If vision problems are detected, do not procrastinate, and timely medical attention is key. Through reasonable prevention and timely treatment, we can effectively protect our eye health.
