Blurry vision can happen for many reasons. You might wake up with hazy sight, experience blurriness when you're tired, or struggle to focus at random times. While often easy to attribute to lifestyle or environmental factors, or to overlook all together, persistent blurriness likely indicates an underlying issue and should be evaluated by an eye doctor.
5 Common Causes of Blurry Vision
Cataracts
Cataracts become more common with age. Around 20% of people between 65 and 74 have cataracts, and this number increases to 50% in those over 75. However, cataracts can also develop earlier in life. They cause clouded, blurry vision and a loss of contrast, making it harder to see details clearly. At night, you may notice halos around streetlights and other bright lights.
Glaucoma
Glaucoma occurs when fluid buildup in the eye increases pressure on the optic nerve, leading to vision loss if left untreated. Blurred vision, tunnel vision, and seeing halos around lights can all be signs of glaucoma. Because the disease often progresses without noticeable symptoms at first, routine eye exams are crucial for early detection and treatment.
Diabetic Retinopathy
If you have diabetes, high blood sugar levels can damage the blood vessels in your retina, leading to diabetic retinopathy. This condition can cause blurry vision, floaters, and eventually permanent vision loss if not managed. Controlling blood sugar levels and having regular eye exams can help slow its progression and protect your eyesight.
Macular Degeneration
Macular degeneration, often age-related, affects central vision and can make it difficult to see fine details, read, or recognize faces. It can occur in one or both eyes and may progress slowly or more rapidly, depending on the type. While maintaining a healthy lifestyle can help reduce risk, early detection is key to managing the condition effectively.
Dry Eye Syndrome
Blurred vision can sometimes be caused by dry eyes. If blinking frequently improves your vision, dryness could be the culprit. Other symptoms may include itching, redness, and discomfort. Artificial tears or other treatments may help relieve dryness and restore clarity.
Blurry vision may also be due to refractive errors such as nearsightedness, farsightedness, or astigmatism, which require corrective lenses.
When to See an Eye Doctor
If your blurred vision continues for an extended period, progressively worsens, or follows a traumatic injury, schedule an eye exam. A comprehensive eye exam can help determine the cause and provide the right treatment to improve your vision.
