Blurred vision refers to an ocular condition in which a person's eyesight becomes unclear or hazy, making it difficult to see objects with sharpness or clarity. It is a common symptom that can affect individuals of all ages and is typically associated with various underlying causes or eye-related conditions.
When a person experiences blurred vision, they may perceive a lack of focus, sharpness, or detail in their visual field. This can manifest as a general blurriness, cloudiness, or distortion of images. The degree of blurriness can vary from person to person, ranging from a slight blurring to a complete loss of visual acuity.
There are numerous potential causes of blurred vision, including refractive errors like nearsightedness, farsightedness, or astigmatism. Other common causes include eye strain, fatigue, dry eyes, or the use of medications that affect the eyes. Blurred vision can also be a symptom of more serious eye conditions such as cataracts, glaucoma, diabetic retinopathy, or macular degeneration.
In some cases, blurred vision may be accompanied by additional symptoms such as eye pain, double vision, headaches, or a sensation of pressure around the eyes. If symptoms persist or worsen, it is advisable to seek medical attention to determine the underlying cause and receive appropriate treatment.
Overall, blurred vision refers to the visual impairment characterized by a lack of sharpness and clarity in a person's eyesight, and it can be a result of various eye-related conditions or systemic factors.
