Understand your eyes. Find the next step.

Clear information about vision changes, eye conditions and care. Start with the question that matters to you, then discuss personal symptoms with an eye-care professional.

Quick answer

Eye-health information can help you prepare for an appointment, but it cannot diagnose the cause of a vision change. WAN’s guides explain conditions, sources and review status. Sudden vision loss or sudden severe eye pain needs emergency assessment; do not wait for a screening camp or charity enquiry.

When should you seek help?

Sudden or severe symptoms

Sudden inability to see or sudden severe eye pain needs emergency care. New flashes, a moving shadow, blurred vision or a painful red eye also need urgent medical advice. Use your local eye-care or emergency service. In the UK, follow the NHS urgent-care guidance linked below.

NHS vision-loss guidance

Gradual changes and routine checks

Arrange an eye examination if vision changes affect reading, driving or daily activities. Bring your glasses, a medicine list and questions. If you already have a diagnosis, follow the review plan your clinician recommends.

Explore 8 eye-condition guides

Each guide links to its sources. The library includes explanations of treatment and support; not every condition is treated with surgery.

Make the most of an appointment

  • Explain when the change began, whether it affects one or both eyes and how it affects daily life.
  • Ask what the tests show, which choices are reasonable and whether treatment is urgent.
  • Ask about benefits, risks, costs, alternatives and follow-up before agreeing to treatment.
  • Confirm whom to contact if symptoms worsen. A funding application should not delay urgent medical care.

Questions about eye care and support

Are these guides a diagnosis?

No. Similar symptoms can have different causes. A guide or online checker cannot examine your eyes, establish a diagnosis or decide whether surgery is suitable.

Have all these guides received clinical review?

No blanket clinical-review claim is made. A named reviewer should only be credited for the exact content version they have signed off. Current review status is stated on each guide; public source references are not the same as a clinician’s approval.

Does eye surgery reverse every kind of sight loss?

No. The appropriate care depends on the condition. Some treatments aim to prevent further damage rather than recover vision already lost. A specialist should explain the realistic benefit for the individual.

Can WAN arrange an urgent appointment?

WAN is not an emergency eye-care service. For sudden vision loss or sudden severe eye pain, seek emergency medical assessment locally. Do not wait for a donation programme or a reply from us.
