How review works · Official biography & credentials

Where to start

An optometrist or ophthalmologist can assess your eyes. The National Eye Institute explains how to find a provider. Contact an eye-care service promptly for new symptoms; use emergency care for sudden sight loss or serious injury.

Referrals, eligibility and costs

Check whether your appointment is covered by medical insurance, a vision plan or neither, and whether the provider is in network. Ask about the examination, imaging, treatment and follow-up costs separately.

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.
