visual field test measures your range of vision to the sides. You must have a visual field of at least 120° with at least 50° to left and right. Drivers with macular degeneration, who lose central vision, often pass this test. The number plate test checks whether you can We do visual field test on lots of people; over 60's, history of glaucoma, those with headaches, odd optic discs, anything unusual basically. They have a steep learning curve, so in people who haven't done one before, the results are less reliable than in people that have. So, we often have to repeat them. The Visual Field. The normal eye can detect stimuli over a 120º range vertically and a nearly 160 degree range horizontally. From the point of fixation, stimuli can typically be detected 60º superiorly, 70º inferiorly, 60º nasally, and 100 degrees temporally (laterally) 2, though the true extent of the visual field depends on several features of the stimulus (size, brightness, motion) as The Driver and Vehicle Licensing Agency (DVLA) have certain medical requirements that drivers need to be able to meet. In terms of vision requirements, you need to be able to pass the “number plate” test, which involves reading a number plate from 20 metres away (for an old-style number plate) or 20.5 metres away (for a new-style number plate). Group 1 drivers must be able to read a number plate in good daylight at a distance of 20m and have binocular acuity of 6/12. They must also meet certain visual field requirements. There are additional requirements for Group 2 drivers. Esterman visual field test score for diff erent field types. Left, binocular passes; centre left, binocular fails; centre right, uniocular passes; right, uniocular fails. Interpretation of the InWLY. designed to shift the visual field in one or both eyes so that objects within a scotoma can be seen, may not be used for testing. A binocular Esterman visual field test may be performed when it is inconclusive that the total horizontal field on the screening exam meets the 110-degree minimum. Examples of Esterman test results may be The Visual Field. The normal eye can detect stimuli over a 120º range vertically and a nearly 160 degree range horizontally. From the point of fixation, stimuli can typically be detected 60º superiorly, 70º inferiorly, 60º nasally, and 100 degrees temporally (laterally) 2, though the true extent of the visual field depends on several features of the stimulus (size, brightness, motion) as Visual field deficits also need to be certified by an optician. This covers drivers until age 70, after which they will need to renew every three years, declaring that they meet the required visual standards [1]. Visual standards for Heavy Goods Vehicle (HGV) and bus drivers in the UK are more stringently set, and understandably so. Visual field test. A visual field test measures how much you can see out of the corners of your eyes. If you notice any blind spots or your visual field narrowing, this could be a sign of glaucoma or diabetic retinopathy. Normal vision. Impaired vision. You must be able to read (with glasses or contact lenses, if necessary) a car number plate made after 1 September 2001 from 20 metres. You must also meet the minimum eyesight standard for driving by having a visual acuity of at least decimal 0.5 (6/12) measured on the Snellen scale (with glasses or contact lenses, if necessary) using both eyes
