If you experience any of these symptoms, you should make an appointment with an eye doctor.

Blurry Vision

If you have blurry vision that causes problems with reading or other everyday tasks, you should get an eye exam to determine if you just need glasses or contacts or if the blurriness is a symptom of a more serious disease.

Loss of Peripheral Vision

A narrowing of the visual field, creating "tunnel vision," is one of the chief symptoms of glaucoma.

Severe Eye Pain

Most eye diseases do not cause any pain, but some types of glaucoma do.

Blind Spots

Black spots within the field of vision can indicate AMD or diabetic retinopathy.

Sudden Loss of Vision or Flashes of Light

Seeing flashes in one or both eyes or the sudden appearance of a shadow or curtain across the field of vision can indicate retinal detachment, which requires immediate treatment to avoid permanent damage or blindness. You will not feel pain when the retina detaches; flashes of light and spots may be the only symptom.

Chronic Red or Irritated Eyes

Dry eye symptoms like redness or pain are common and usually do not require treatment. But if symptoms continue for more than a few days, they may indicate a serious problem.
