Introduction
In general, blurred vision may be caused by eye strain, myopia, dry eye syndrome, cataracts, glaucoma, or other conditions. If any discomfort occurs, it is recommended to seek medical attention promptly. Prolonged use of the eyes may lead to eye strain. At this time, the eye's focusing ability may decline, resulting in blurred vision. It is advised to immediately close your eyes and rest, and reduce the amount of time spent using your eyes.
Under normal circumstances, blurred vision may be caused by eye strain, myopia (nearsightedness), dry eye syndrome, cataracts, glaucoma, or other conditions. If any discomfort occurs, it is recommended to seek medical attention immediately. Specific analysis is as follows:
1. Eye strain: Prolonged use of the eyes may lead to eye strain. At this time, the eye's focusing ability may decline, resulting in blurred vision. It is recommended to close your eyes and rest immediately, and reduce the duration of eye use.
2. Myopia: Myopia is a type of refractive error in which the eye cannot properly focus on distant objects, causing them to appear blurry. Individuals with myopia typically experience blurred vision when looking at distant objects. Vision can be corrected by wearing glasses after consulting a doctor.
3. Dry eye syndrome: Dry eye syndrome results from insufficient lubrication on the surface of the eye, which may affect visual clarity and focusing ability, leading to blurred vision. Treatment may include medications such as sodium hyaluronate eye drops, Jinzhen eye drops, or fluorometholone eye drops, used under a doctor’s guidance.
4. Cataracts: A cataract occurs when the eye's lens becomes cloudy, impairing light transmission and the eye's focusing ability. When the lens clouds over, vision may become blurry or shadowy, and severe cases may lead to complete blindness. It is recommended to follow medical advice and use medications such as phacolysin eye drops, reduced glutathione eye drops, or Noksin eye drops to help alleviate symptoms.
5. Glaucoma: Glaucoma is a condition in which increased intraocular pressure damages the optic nerve, potentially causing blurred vision, visual field defects, and other symptoms. Optic nerve damage may result in blurred vision or even blindness. Treatment may include medications such as mannitol injection, betaxolol hydrochloride eye drops, or carteolol hydrochloride eye drops, as recommended by a physician.
In daily life, it is recommended to maintain good eye habits and avoid rubbing the eyes, which helps preserve eye health.
