Eyesight Frequently Asked Questions


Frequently Asked Questions #

  • Can I test my eyesight at home?

    You can perform basic eyesight checks at home, like reading texts at various distances, but these are not substitutes for a professional eye examination.

  • Are eyesight tests free?

    In the UK, NHS eye tests are free for certain groups, such as those under 16, over 60, or with specific medical conditions.

  • Can I get a free eye test if my mum has glaucoma?

    If your mother has glaucoma, you’re entitled to a free NHS eye test in the UK as you’re at a higher risk.

  • What does 20 50 vision look like?

    With 20/50 vision, what a person with normal vision can see clearly at 50 feet, you would need to be 20 feet away to see equally clearly.

  • How do you know if your vision is OK?

    Signs of good vision include clear and sharp vision at different distances, no frequent headaches, and no blurred or double vision. Regular eye tests are important for confirmation.

  • What eye problems need immediate attention?

    Sudden changes in vision, severe eye pain, eye injury, flashes of light, or a large number of floaters require immediate medical attention.

  • Why can I suddenly see better without my glasses?

    A sudden improvement in vision without glasses may indicate changes in blood sugar levels or other health issues and should be checked by a professional.

  • What are eye floaters?

    Floaters are small, shadowy shapes or specks that drift across your field of vision, typically more noticeable against bright backgrounds.

  • What is considered very bad vision?

    Very bad vision generally refers to visual acuity significantly worse than the standard 20/20 or 6/6, often not fully correctable with glasses or contact lenses.

  • Why is my left eye so blurry?

    Blurry vision in one eye can be due to a number of factors including refractive errors, cataracts, or more serious conditions, necessitating an eye examination.

  • Why do I see GREY in my vision?

    Seeing grey or having a grey spot in your vision can be a sign of an eye health issue and should be evaluated by an optometrist or ophthalmologist

  • What are the normal signs of aging eyes?

    Normal aging signs include presbyopia (difficulty focusing on close objects), needing more light to see, changes in colour perception, and dry eyes.

  • Are all opticians eye charts the same?

    Most opticians use standardised eye charts for vision testing, but there can be variations, especially in the types of charts used (e.g., Snellen, LogMAR)

  • Is 6 5 vision OK for driving?

    6/5 vision (better than the standard 6/6 or 20/20) is excellent and more than adequate for driving in the UK.

  • How far down the eye chart is 20 20?

    The 20/20 line on an eye chart is typically situated towards the bottom, as it represents the standard for normal visual acuity.

  • What happens if you can’t read the eye chart?

    If you’re unable to read the eye chart, the optician will use other methods to assess your vision and determine the correct prescription or identify any eye health issues.
