Everything you need to know about your eye examination


There are many different ways in which to assess eyesight, I select the most appropriate to the individual using the latest technology.

Some of the technology I use in my practice include:

FDT Frequency Doubling Technology

Fast and effective test of visual field (peripheral vision), a key indicator to rule out glaucoma.

Auto Refractor

non contact tonometer



OCT (Optical Coherence Tomographer)

Produces a wide-angle high-resolution fundus image in a split second allowing us to rule out macular degeneration and glaucoma.

Slit Lamp

Used in conjunction with a biomicroscope, it provides a microscopic exam of eyelids, sclera, conjunctiva, iris and cornea,using a high intensity light source.


Elements to your eye examination

The following areas will be examined to your individual requirements and used in determining your prescription and the health of your eyes.

Full history. Since many eye problems are related to physical health and hereditary factors, problems experienced by you or your family will be identified and taken into account.

Internal Eye pressure.  The result can indicate the possible presence of Glaucoma. This condition is usually found in adults over the age of 40.

Visual field screening. Visual field screening checks for your all round vision and can indicate neurological problems.

Colour perception. This can indicate colour blindness. As this is normally a stable hereditary condition, the test is usually only carried out at your first visit.

Muscle balance analysis. This determines if your eyes are co-ordinated and working properly.

Interior and exterior of eyes.  Examination of the various parts of the eye can give an overall picture of the condition of your eyes and your general health.

Stereoscopic acuity. Mainly used with children, this examination helps in the detection of a ‘lazy’ eye.

Pupil reflexes. Pupil reflexes examine your pupil’s reaction and may indicate neurological problems.

Visual acuity and vision assessment. Measures your vision with and without spectacles. An instrument called a focimeter also ‘reads’ the prescription in existing spectacle lenses.

Prescription assessment – Refraction. Objective tests (where I will observe the results) and subjective tests (where you as a client will say what you see) determine whether you are longsighted, short-sighted, astigmatic, presbyopic, or have no optical error at all.

I’ll explain all the results of your examination to you and give you a record for any prescription or special instructions. At the end of your Eye Test, I will also recommend when it will be advisable for you to return for your next appointment.


What makes us different to other Optometrists?

OCT; akin to an MRI scan, this is included in the price of a private eye examination at Brad Abrahams. For more information on this advanced technology click here.
