How is blurred vision diagnosed?

As there are many potential causes of blurred vision, it is important to see your doctor, optometrist or ophthalmologist for an accurate diagnosis.

If an underlying medical cause is suspected, your doctor may also refer you for blood tests.

How can I protect my vision?

Follow these recommendations to protect your vision:

  • have regular eye check ups — if you do not have any eye diseases or are not at risk, have an examination every 2 years by a registered optometrist or ophthalmologist
  • protect your eyes from UV light — wear sunglasses with good UV protection and a hat to protect against some eye diseases
  • follow a healthy lifestyle — a balanced diet high in antioxidants, omega 3 fatty acids, vitamins and minerals can slow down macular degeneration or diseases causing blurry vision such as diabetes
  • quit smoking
  • protect your eyes from hazards — wear safety glasses to protect against eye injury

It is especially important to look after your eyes if you have diabetes. Maintaining stable blood glucose levels can reduce your chance of developing diabetic eye problems.

Maintaining healthy blood pressure and cholesterol levels can also reduce your chance of other health problems that can affect your eyes, such as stroke.
