Frequently Asked Questions

What are the 7 warning signs of eye disease?

Sudden/persistent blur, severe pain or redness, new flashes/floaters, double vision, abnormal discharge or photophobia, cloudy/wavy vision, and central/peripheral field loss.

Is sudden vision loss an emergency?

Yes. Seek urgent medical or ophthalmic assessment.

Is gradual blurry vision always disease?

No. Refractive error, dry eye, presbyopia and cataract are common causes, but persistent blur should be checked.

What if one eye suddenly becomes blurry?

A sudden one-eye change deserves urgent assessment.

Are new flashes and floaters dangerous?

They can be. A sudden increase, especially with a curtain or shadow, requires prompt retinal assessment.

What does a curtain over vision mean?

It can be a retinal-detachment warning sign and needs urgent care.

Is severe eye pain with nausea urgent?

Yes. Acute angle-closure glaucoma is one possible emergency cause.

Can glaucoma have no symptoms?

Yes. Common glaucoma can be silent early.

Is high eye pressure the same as glaucoma?

No. It is a risk factor; glaucoma is optic-nerve damage.

New wavy straight lines can indicate macular disease.

Can cataract cause cloudy vision?

Yes, typically gradually.

Is cataract usually an emergency?

Typical age-related cataract is usually gradual, not an emergency.

Yes, often fluctuating and sometimes improving after blinking.

Abnormal light sensitivity; with pain/redness/blur it may indicate corneal or intraocular disease.

Reduced side vision, which can occur in glaucoma, retinal or neurological disease.
