Symptoms that need prompt care

Seek urgent medical or eye care for sudden vision loss, severe pain, new flashes or floaters, a curtain-like shadow, eye injury, chemical exposure, new double vision or light sensitivity with pain.

Why triage matters

Many symptoms are minor, but some can signal retinal, inflammatory, neurological or injury-related problems. The safest next step depends on timing, severity and whether vision has changed.

Routine symptoms still deserve attention

Blur, headaches, dry eyes, watering, redness or contact lens discomfort can often be booked as an optometry appointment if they are not sudden or severe.

Common questions

Are sudden flashes or floaters urgent?

Yes. Sudden new flashes, many new floaters or a curtain-like shadow should be checked promptly.

Should eye pain wait for a routine appointment?

Severe eye pain, pain with light sensitivity, or pain with vision change should be treated as urgent.

Can iFocus help me decide where to go?

For sudden or severe symptoms, seek urgent medical or eye care promptly. For non-urgent symptoms, iFocus Optometrists can help with eye tests and advice.
