Eye Conditions Explained

Brain tumours are rare, but they do happen.

10 children and young people are diagnosed each week in the UK and early diagnosis can improve the outcome.

A regular eye test may help in the early detection of a brain tumour.

Recognising the signs of a brain tumour

Diagnosing a brain tumour is not easy and the initial symptoms may mimic those of less serious illnesses. Symptoms of brain tumours vary according to tumour location and the age of the child or young person, but common signs include:

  • Persistent or recurring headaches
  • Persistent or recurring vomiting
  • Poor balance
  • Difficulty walking
  • Abnormal eye movements
  • Deteriorating, blurred or double vision
  • Fits or seizures
  • Behaviour change

Any child or young person with symptoms that are unusual for him or her, or are persistent or unexplained, should be seen by a GP. Please remember anyone needing urgent medical help should be taken to the nearest emergency department or dial 999.


As we get older, the flexibility of the lens inside your eye reduces, which in turn causes issues when trying to focus on close concentrated tasks such as reading a book or using a computer device. This is called Presbyopia and can be corrected with reading spectacles or contact lenses.


Astigmatism, like being short sighted or longsighted, is a focussing error in the eyes and can easily be rectified by prescription spectacles or Contact Lenses. Having Astigmatism is not a health problem or disease of the eye but if you are concerned with your vision, a simple trip to Haine and Smith Opticians will eradicate your worries.

What are floaters?

Often, people who have otherwise healthy eyes see floaters. They appear as spots, lines or cobweb effects, usually when you look at a plain surface such as a white wall or clear blue sky. They often appear when the clear jelly in the main part of your eye gets older.

What are flashes?

Sometimes the jelly in the main part of your eye shrinks a little and tugs on the retina (light sensitive layer) at the back of your eye. This can cause flashes of light at the edge of your vision particularly in dim light. These differ from the disturbance of vision that can occur with migraine.

When should I be concerned?

If you suddenly notice a shower of new floaters, or floaters along with flashes or a cobweb or dark shadow or “curtain” like effect in your vision these may relate to a tear at the back of the eye and you should seek advice immediately. Early detection of a tear is important to ensuring the best outcome should treatment be required.
