Eye Examinations

The Optometrists at Krishna Vision Opticians carry out a thorough eye examination on all patients, to check the quality of your vision and eye health.

This primarily involves taking a detailed history of your eyes, health and symptoms. The Optometrists check the prescription of your eyes using an array of both objective and subjective methods. The health of the eyes is checked using a technique that allows the optometrist to focus on the internal structures of the eye. In appropriate groups we also examine colour vision, 3D and eye muscle balance (for children); defects, eye pressure and visual fields (for all patients aged 40 and above). We have many methods of analysis for specific conditions including macula degeneration and diabetes.

Retinal photography is also used to enable our Optometrists to capture digital images of the retina of the eyes. This gives both the Optometrist and the patient a permanent record of the health of the retina. Hence regular retinal imaging can help detect changes in the eye that can occur over a period of time. The test is extremely useful for all patients, especially those with diabetes, glaucoma, blood pressure, macula degeneration and a huge variety of other eye and health conditions. Retinal photography is therefore advisable to every patient

These procedures enable us to advise our patients appropriately on what action needs to be taken to help improve their vision and eye health.  Through these and further rigorous testing procedures, we are also able to identify a number of health concerns which we report back to the patient to act upon via their GP. Who can then act under the advice of their GP

It is recommended that you visit an optometrist every years (or as advised).  This is important because an eye examination can detect potentially blinding eye conditions.

It is easy to neglect the eyes because they rarely hurt when there is a problem. But once eyesight is lost, it may never be restored.




Why are regular eye tests (sight tests) so important?

It’s easy to neglect your eyes because they rarely hurt when there’s a problem.

Having an Eye Test won’t only tell you if you need new glasses or a change of prescription, it’s also an  important eye health check. It can spot many general health problems and early signs of eye conditions before you’re aware of any symptoms – many of which can be treated if found early enough.


How often should I have an eye test?

It’s recommended that you have a sight test every two years (or more frequently if advised).


What should I do if I notice a change in my sight?

Visit your optician or GP if you’re concerned with any aspect of your vision at any time.


Are some people more at risk from eye disease than others?

Anyone can develop sight problems, but some people have a higher risk of eye disease. It’s especially important to have regular eye tests if you are:

  • above 60 years old
  • from certain ethnic groups; for example, people from African-Caribbean communities are at greater risk of developing Glaucoma and diabetes, and people from south Asian communities are at a greater risk of developing DiabetesDiabetic Retinopathy, in which the retina becomes damaged, is a common complication of diabetes
  • someone with a learning disability
  • from a family with a history of eye disease

What about my child’s sight?

Children do not usually complain about their sight, but may show signs of not being able to see properly.

Things to look out for include sitting close to the TV, holding objects very close to their face, blinking a lot, eye rubbing, or one eye turning in or out.

If your child is having any sort of sight problems, take them to an optometrist for further investigation.

Children don’t have to be able to read letters to have their eyes examined. Like adults, children should have regular eye checks around once a year.

NB: Children’s Eye Development

  • Remember to take your child to all their developmental checks.
  • Eye problems can develop at any age. Not all parents are even aware that their child has an eye problem.
  • If you have concerns, ask your optometrist, GP, health visitor or school nurse for advice.
  • Free NHS funded sight tests are available for children under 16 years of age and those aged 16 to 18 and in full-time education.


Can I get help with the cost of a sight test of glasses?

Lots of people are entitled to free NHS-funded sight tests and an optical voucher, which will help with the cost of glasses or contact lenses.
