Eye Examination

A comprehensive eye exam at Nu-Sight will involve several different stages during which your optometrist will fully assess every aspect of your eye health and vision. Depending on the type of eye exam you have, it will last anywhere between 20 minutes to an hour.

History & Symptoms

At the start of the examination, your optometrist will discuss your vision and eye health to pinpoint any potential areas of concern. They will also ask questions about your general lifestyle, health, and medical history. This will involve finding out more about:

This information will help your practitioner to make an accurate assessment of your needs, gauge the general health of your eyes and your ability to see before starting the examination.

Examining Your Eye

Your eyes will be examined both externally and internally to assess their health and identify any other underlying medical problems.

Depending on the examination you are having, your optometrist will use various instruments to examine and record the state of your eye health. Our most advanced eye examinations include specialist, high-tech equipment such as our Optomap Retinal Scanning Camera and our Optical Coherence Tomographer (OCT) Scan which provide a thorough view of the eye and vision performance. We also take high quality digital images of your central retina to keep on record for future comparisons.

OCT Scan

OCT (Optical Coherence Tomography) is a new imaging technique that offers a ‘high-definition’ detailed cross-sectional image of the back of the eye. The OCT works in a similar way to ultrasound. It’s able to take 128 individual scans and create a 3D view of either the optic nerve (the nerve that sends a signal to the brain) or the macula (central vision area). This enables us to understand, detect and monitor eye problems easily. The scan is completely painless, quick to perform and nothing touches the eye.

The OCT is useful in the early diagnosis and management of many conditions including

Optomap Retinal Scan

The Optomap gives a wide angle digital scan of the retina. This allows us to scan and view a 200° area of the retina whilst the more commonly used traditional retinal camera only manages to scan and view the central 30°. This enhances our ability to detect even the earliest signs of disease and health issues including heart disease, hypertension, diabetes and strokes. The scan causes no discomfort, nothing touches your eye and is recommended for all patients including children. The digital image is captured in seconds and is immediately available for your optometrist to review.

Testing Your Vision

Your vision will be measured both with and without spectacles or lenses to check for any problems with your eyesight. Your optometrist will assess your distance vision (for TV, driving and walking around), your near vision (for reading, computer and close work) and your vision at other points, depending on your specific lifestyle needs.

Your Eye Examination Results Explained

At the end of your eye exam, your optometrist will have detailed knowledge of the condition of your eye health and vision. They will discuss with you and ensure you have a full understanding of your results and what preventative measures – if any – need to be taken to protect your eyesight.

They will then make recommendations of the best eye care solutions for you individually before handing you over with a clear and thorough explanation to a Dispensing Optician or Optical Advisor who can help you with spectacles or contact lenses if required.

If you do require spectacles and/or lenses, we will need to take more measurements once you have selected your frames. This is because we’ll need to ascertain several different measurements including the distance from the spectacle lens to the centre of eye rotation, the distance between your pupils and the height that your pupil sits in the frame. This information will allow us to further improve the precision of your spectacle lenses to ensure optimum performance and eye health.

We will take these measurements as part of the dispensing process and will explain how we can help to make your vision as sharp and clear as possible. We will also discuss other spectacle lens options and benefits to suit your lifestyle needs.
