What causes blurred vision?

Blurred vision is a nuisance, especially if you are used to having perfect vision. In some cases, your optician can help with new glasses or contact lenses and this is a good place to start.

As we get older we all lose the ability to read things closer to us, so the probability of having blurred vision increases. This is known as presbyopia. It usually happens around the age of 45. You start to hold your book or newspaper further away and this helps at first. However, the need for reading glasses is eventually universal.


What Patients Say About Laura Crawley

I had the best experience working with Dr Crawley. I felt looked after and she took the time to get to know me. I would highly recommend her.

Sven K. | Brighton

From the moment I met her to the moment I left, I was treated with great courtesy and kindness, and everything was explained to me in layman’s terms so I could fully understand my condition. I was immensely impressed.

Mariah P. | London

Dear Laura,
Just a quick note to say thanks for looking after my mum Mrs M. so wonderfully. It was so good of you to take so much time and care as she was very worried about my appointment and you really made such a difference to my experience. Thank you.

Ruth S. | Oxford

Dear Angela and Laura,
Thank you very much for seeing me yesterday. You were both marvellous and a pride to the NHS. You could, if you two wish, send this to your line manager. Thank you again!

Rebecca K. | Brighton

Dear Laura,
Enjoy your holiday and thanks for everything so far.
Best Wishes

Do not ignore the symptoms of blurred vision

Needing glasses for distance and near work does not usually signify a serious problem with your eyes. However, there are some symptoms associated with blurred vision that you should not ignore and when you should see an ophthalmologist promptly:

  • if straight lines look distorted or crooked,
  • if the blurred vision is painful or you feel sick with it or
  • if there is a shadow in your vision through which you cannot see

These symptoms are associated with retinal problems such as macular degeneration, acute glaucoma or retinal detachment. Prompt examination and treatment can save your vision, so if there is something unusual or sudden about your blurred vision, please book an urgent appointment with an ophthalmologist. My expert team and I am very experienced in all types of ophthalmic emergencies and will be able to offer you the best advice and treatment.
