The binocular Esterman test may be used for drivers with at least 110˚ but less than 120°. If test passed without missing any points, no road test will be required. Missing one to three points on the Esterman test requires passing a road test. Missing four points on the Esterman test will disqualify for driving.
The Esterman test detects any blind spots in your visual field (when you've got forbidden to give the interpretation of fields because that's down to the DVLA.

Se hela listan på aao.org 2018-04-17 · To evaluate the defects in the central and peripheral visual fields, researchers used the Humphrey 24-2 tests for both eyes and the Binocular Humphrey Esterman VF test (EVFT) (Carl Zeiss Meditec). The Esterman test, the only standard binocular field test available, is used to determine the extent of VF in UK drivers,43 although it was not originally designed for this purpose.40 Although some studies suggest that the Esterman test is a good predictor of visual function,36 44 45 its limitations are well documented and include a substantial ceiling effect which limits the test’s False positives are primarily important in tests that have defects—they are not a reason to invalidate an otherwise unremarkable or clear visual field test. If this index is higher than 15%, the test needs to be invalidated or repeated (even 5% to 10% should be scrutinized).Tests with high false positives are automatically removed from a Humphrey Guided Progression Analysis (GPA). My Driving licence was revoked on the basis of the Esterman Test of my Visual Fields. My eyesight is perfect for all normal purposes, using spectacles only for reading.

One of the ways the DVLA can assess this is using the Esterman test. It's quick, straightforward and is designed to make sure you have an adequate field of vision. At Gilroy Opticians in Belfast, we can carry out the test and provide you with the required paperwork and can have a look at your prescription if necessary. Visual field tests measure the total area that is seen while the eye is directed straight ahead. The total visual field with both eyes open is approximately 180° horizontally and 155° vertically. A visual field of less than 60° will start to significantly impact on a person’s ability to move about within the environment.
