Blurry vision is a common symptom that can be caused by various factors, including eye conditions, underlying diseases, and injuries. Some of the most common causes of blurry vision are:

• Refractive errors: These occur when the eyes cant focus images correctly, and they include conditions such as nearsightedness, farsightedness, and astigmatism. Refractive errors are the most common cause of blurry vision, and they can often be corrected with eyeglasses, contact lenses, or surgery.

• Dry eye syndrome: This occurs when the eyes dont produce enough tears or the tears evaporate too quickly, leading to dryness, irritation, and blurry vision.

• Cataracts: These are cloudy areas that form in the lens of the eye, leading to blurry vision, glare, and halos around lights. Cataracts are more common in older adults, but they can also affect younger people.

• Glaucoma: This is a group of eye diseases that damage the optic nerve and can lead to vision loss. One of the early signs of glaucoma is blurry vision, especially in the peripheral vision.

• Diabetes: High blood sugar levels can damage the blood vessels in the retina, leading to a condition called diabetic retinopathy. This can cause blurry vision, floaters, and even blindness if left untreated.

• Migraines: These are severe headaches that can cause visual disturbances, including blurry vision, flashing lights, and blind spots.

If you experience sudden changes in your vision, its important to seek medical attention immediately, as it could be a sign of a serious condition such as a stroke, retinal detachment, or a brain tumor. Regular eye exams can also help detect and treat any underlying eye conditions that may cause blurry vision.
