How review works · Official biography & credentials

Where to start

An optometrist can check routine vision changes and arrange an eye-service referral. Urgent pathways differ across the UK. NHS 111 can help direct urgent care when you are unsure; sudden sight loss or a serious eye injury needs emergency assessment.

Referrals, eligibility and costs

Eligibility for NHS-funded sight tests depends on your circumstances and the UK nation where you live. Ask the optician or local NHS service what applies before booking.

Keep your eye-care appointments

Glaucoma and diabetic retinopathy can develop before vision changes are noticeable. Ask your eye-care team which examinations you need and when to return. Your age, medical history, family history and previous results affect this plan.

When to seek immediate help

Sudden loss of sight, a dark curtain over vision, a serious eye injury or severe eye pain needs immediate assessment. New flashes or suddenly increasing floaters need urgent eye care. Do not wait for a routine screening appointment.
