Vision Toolbox vs Near and Far

Thomson Software Solutions is the leading provider of software for eye care professionals in Europe and has users all over the world. This application joins a family of software for vision assessment and screening originally devised by Professor David Thomson. Replace all your test types, near charts, near testing units etc. with over 500 test screens and images in one slick application. The Vision Toolbox exploits the superb graphics capabilities of the iPad to provide a huge range of vision assessment tools for eye care professionals (ophthalmologists, optometrists, orthoptists and opticians). Access different tests by simply rotating the iPad and view variations by swiping the screen. Select the test that you want directly by viewing the thumbnail gallery and draw on the screen using your finger. Pan and zoom some of the images or display as a slide show. No eye care professional can afford to be without it! The tools are divided into five categories: Near vision assessment: By holding the iPad at a normal reading distance, The Vision Toolbox can be used to assess a wide range of near vision functions including: - Test types (Adult and children's test types) - LogMAR reading test - LogMAR near charts - Task images (Maps, books, newspaper etc. to ensure the patient can perform these real world tasks) - Binocular vision tests (fixation disparity, binocularity, suppression, stereopsis, 3D red/green anaglyphs) - Duochrome (dots, letters, rings) - Amsler (positive and negative contrast, draw directly on charts and email the results) - Fixation targets (clown, crosses, letters, cartoons) - Miscellaneous (convergence, astigmatism, Maddox rod) 3 metre assessment: View Vision Toolbox from 3 metres and you can assess a wide range of distance vision functions. Handy for home visits, vision screening or testing children. - LogMAR charts - Snellen charts - Single letter charts - Children's visual acuity (Tumbling Es, linear logMAR) - Duochrome (dots, letters, rings) - Cross cylinder (dots and rings) - UK number plate test for driving (actual number plate fonts and correct spacing) - Fixation targets (clown slide show to use during retinoscopy for example) Patient information: Wide range of images to help explain conditions to patients. Select the required image from a thumbnail gallery. Pan and zoom on all images and draw with your finger. - Eye diagrams - Eye disease (photographs of a wide range of anterior segment eye diseases) - Front of the eye (images of the external eye) - Retina (normal and abnormal fundi) - Dispensing images - Videos Dispensing tools: Replace your frame rule with a selection of on-screen rulers, protractors etc. Take advantage of the back-illuminated screen to measure CDs, bifocal heights, varifocals etc. Toolkit: Use the toolkit to perform those tricky eye-related calculations. - Visual acuity (convert between LogMAR, VAR, Snellen metres, Snellen ft, Resolution and Spatial frequency) - LogMAR scorer (help with scoring a LogMAR chart) - Vertex distance calculator - Toric contact lens over-refraction calculator - Transposition calculator

Near and Far is a simple near and distance visual acuity screening tool for near and distance visual acuity for iPad™. The distance (far) test is based on a traditional Snellen chart. The distance test optotypes are of the Sloan type and are limited to the letters specified in the British Standard BS 4274-1:2003. They are designed to be read at 6 meters or 20 feet, but can be reversed for use with a mirror at 3 meters or 10 feet if necessary by left or right swiping the screen. To toggle between 3 meters and 20 feet, tap on the size indicator on the lower right of the far test screen. The letter combinations can be randomized by tapping on them. Potentially offensive letter combinations are filtered out. The near vision test uses the N type chart and features three sets of text which can be cycled by tapping on the text. Either Helvetica or Times New Roman font can be displayed. The test screens have been designed with minimal visible controls. There are no visible controls on the Near screen, and only "Smaller", "Larger" and Size controls on the "Far" screen. To return to the app home screen from any screens you swipe down. Due to the size requirements for the text, Near and Far is an iPad only app. It is necessary to manually calibrate the app via the "Calibrate" screen, before the "Near" and "Far" buttons are enabled. Calibration is necessary due to variations in scaling for the various existing iPad models as well as unknown future models. Calibration is performed by measuring a test line on the calibration screen. All features are enabled on the standard version. There are no In App Purchases and no advertisements. Warning: Vision testing and diagnosis of vision disorders should be performed by appropriately qualified health professionals in an appropriate environment. It is the responsibility of the user of this app to ensure that it is correctly calibrated and suitable for the intended use.
