Looking After Your Vision

Regular eye examinations help detect many eye diseases before symptoms develop.  The recommended frequency of eye examinations varies depending on your age, health, vision and risk factors. 

If it has been some time since your last eye examination, or if you notice any change in your vision, arrange an appointment with your optometrist.

Knowing the warning signs of serious eye conditions can help you seek care promptly.  Sudden changes in vision should never be ignored, as early assessment and treatment can often reduce the risk of vision loss.

Potential Eye Emergencies

The following signs and symptoms may indicate a serious eye or health condition requiring urgent assessment. Seek immediate advice from an optometrist, ophthalmologist, emergency department or GP if you experience:

A sudden shower of floaters or flashes of light

Floaters are common and are often caused by age-related changes within the eye. However, a sudden increase in floaters, especially when accompanied by flashes of light or a shadow in your vision, can indicate a retinal tear or retinal detachment. Prompt assessment is essential.

A dark shadow or "curtain" across your vision

This may be a sign of retinal detachment, where the retina separates from the back of the eye.  Retinal detachment can lead to vision loss if not treated promptly.

Sudden eye pain, redness, nausea or vomiting

These symptoms may indicate acute angle-closure glaucoma, a sight-threatening condition caused by a rapid increase in eye pressure. Urgent treatment is required.

Sudden double vision

Double vision can result from eye muscle or neurological disorders. In some cases, it may be associated with serious medical conditions such as stroke. New or sudden double vision should be assessed urgently.

Sudden loss or blurring of vision in one eye

A sudden change in vision may indicate a serious eye condition affecting the retina, optic nerve or blood supply to the eye. Early diagnosis and treatment can be critical in preserving vision.

Eye Problems That Need Prompt Assessment

The following conditions are not usually emergencies, but they should still be assessed by an optometrist as soon as practical.

Gradual loss of peripheral (side) vision

A narrowing of your field of view may be caused by glaucoma. Because glaucoma often develops without noticeable symptoms, regular eye examinations are important for early detection.

Gradual loss of central vision or distorted vision

Symptoms such as blurred central vision or straight lines appearing wavy may be associated with age-related macular degeneration (AMD). Early detection may improve treatment options and outcomes.

Cloudy or blurred vision, halos around lights, or faded colours

These symptoms may occur with cataracts, a common age-related clouding of the eye's natural lens. Although cataracts are usually not dangerous, vision often gradually worsens until treatment is required.

Blurred vision, floaters or blind spots in people with diabetes

These may be signs of diabetic retinopathy. Importantly, diabetic retinopathy can develop without noticeable symptoms in its early stages, making regular diabetic eye examinations essential.

Dry, irritated or uncomfortable eyes

Symptoms such as burning, grittiness, tearing or fluctuating vision are commonly associated with dry eye disease. Although dry eye is usually not sight-threatening, it can significantly affect comfort, reading, screen use and overall quality of life. Your optometrist can recommend appropriate management options, including lubricating eye drops and other treatments.
