Blurred vision can be caused by various factors, including:
-
Refractive errors: These occur when the shape of the eye does not bend light correctly, resulting in blurred vision. Common refractive errors include nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.
-
Eye conditions: Certain eye conditions, such as cataracts, glaucoma, macular degeneration, and diabetic retinopathy, can cause blurred vision.
-
Age-related changes: As we age, our eyes undergo changes that can affect our vision, such as presbyopia, a condition that makes it difficult to focus on close objects.
-
Eye strain: Spending long hours staring at a computer or digital screen, reading in poor light, or driving long distances can cause eye strain, leading to blurred vision.
-
Medications: Some medications, such as antihistamines, antidepressants, and blood pressure medications, can cause blurred vision as a side effect.
-
Head injury: A head injury can damage the optic nerve or the brain, leading to blurred or double vision.
