Blurred Vision in Adults

Common Causes

• Refractive errors (like nearsightedness or astigmatism) — These common eye focusing problems may blur vision in adults due to changes in the eye's shape over time.
• Dry eyes — Reduced tear production in adults might lead to a film over the eyes, causing temporary blurriness that improves with blinking.
• Diabetes or diabetic retinopathy — High blood sugar could damage retinal blood vessels in adults with diabetes, leading to blurred vision.
• Migraines — Research suggests migraines may cause blurred vision in adults as part of an aura before or during headaches.
• Medications (like steroids) — Certain drugs might affect eye fluids or focus, blurring vision in some adults.
