Why Did My Vision Suddenly Become Blurry?
Eyes are often referred to as the windows to the soul and are one of the most important organs in the human body. Through our eyes, we can observe the beautiful things outside. However, improper and prolonged use of the eyes may cause them to be affected, resulting in blurred vision or even significant discomfort. Therefore, when our eyes suddenly become blurry and unable to see clearly, we must understand the causes and seek targeted diagnosis and treatment.
a. Prolonged Close-Up Reading: Students who spend long hours reading up close can easily cause muscle tension and fatigue around the eyes. Over time, this can lead to myopia and sudden blurring of vision.
b. Inadequate Lighting: Reading or looking at things in either too dim or too bright lighting can easily fatigue the eyes, causing sudden blurriness.
a. Prolonged Computer Screen Gazing: Working for extended periods staring at a computer screen keeps the eyes in a state of tension and fatigue, leading to sudden blurring of vision. Appropriately reducing screen brightness can help prevent eye fatigue.
b. Insufficient Sleep: White-collar workers often stay up late for work, resulting in insufficient sleep. Getting up early in the morning without adequate rest can easily cause sudden blurriness in their eyes.
a. Glaucoma: Due to increased intraocular pressure, the ocular tissues cannot bear their own pressure, leading to decreased bodily functions and glaucoma. Causes may include a family history or be strongly related to factors such as excessive fatigue, prolonged work in dark rooms, intravenous infusions, or the use of atropine medications. Patients with glaucoma may experience sudden blurring of vision and unclear sight in the early stages.
b. Vitreous Opacity: As elderly people age, their vitreous humor can deteriorate. Especially for elderly individuals with hardened blood vessels, vitreous opacity can be induced by vascular rupture and hemorrhage or changes in vascular permeability, leading to sudden blurriness in vision.
