The main symptom of vision loss is not being able to see properly.
It can gradually get worse over time or happen suddenly. It can affect 1 or both eyes.
Symptoms of vision loss can include:
You can have vision loss at any age, but it's more common as you get older.
Vision loss in children is rare, but any problems will usually be found during routine eye tests for children.
Speak to your health visitor or GP if you're worried about your child's vision.
Early diagnosis and treatment may help stop your vision getting worse.
You can call 111 or get help from NHS 111 online.
Do not drive to A&E. Ask someone to drive you or call 999 and ask for an ambulance.
Bring any medicines you take with you.

Treatment for vision loss depends on what’s causing it.
If the optician or GP thinks your vision loss is caused by a condition, you’ll usually be referred to an eye specialist (ophthalmologist) for further tests.
The ophthalmologist will discuss any available treatments with you that may improve your vision or may help stop it getting worse. Treatments may include medicines or surgery.
Some conditions can cause permanent vision loss that cannot be treated.
If you have long-term vision loss, the ophthalmologist or GP should refer you to local services that can support you with adapting to living with impaired vision.
Everyone experiences vision loss differently.
If you have permanent vision loss, support you may need can include:
If you've been assessed by an ophthalmologist who says you have severe sight impairment (blind) or you're sight impaired (partially sighted), you can register as sight impaired with your local authority.
This can help you access low vision support and services in your area, and means you can apply for benefits.
Royal National Institute of Blind People (RNIB) is a national charity that offers information and support for anyone affected by vision loss.
