Vision Scan features four different types of checks; Near Vision (for Myopia), Color Vision Deficiency, Amsler Grid and also Contrast Sensitivity for your eyes and generate results which are stored in your iPhone device so that you can share vision scan results with your eye doctor for his reference. Near Vision Check Myopia is a common cause of blurred vision. Using this simple check you can verify level of your visual efficiency. You are provided with alphabets in upper panel to identify and select from the options given below. The size of the alphabets reduces with each level you pass. The check continues till you give the answer correct and as soon as your answer does not match with required answer, your result is displayed to you. You can share this result with your doctor. Color Vision Deficiency Check Color vision deficiency is defined as a lack of perceptual sensitivity to certain colors. Certain people cannot make out the difference between some couples of complementary colors. In this check (known as Ishihara Color Test) you are provided with series of pictures of colored spots. A figure is embedded in the picture as a number. You need to identity the number and select the appropriate answer from the options given besides the picture. The result card is generated showing your answer compare to the answer of a person with normal vision. You can share your result card with your doctor. Amsler Grid Check This check is designed to detect any kind of visual disturbance which may be caused by some changes in retina, optic nerve or the visual pathway to the brain. Look at the grid with each eye separately at the small dot in the center of the grid. Mark the grid if you see any wavy lines or some missing lines. The result of each eye is stored in iPhone device and can be referred by doctor to diagnose the actual location of problem. This check helps to diagnose any macular disease in the eyes. Contrast Sensitivity Check This check determines how well your eyes function in low light and how well you can distinguish objects from similarly colored or shaded backgrounds. A contrast sensitivity check is a special way to measure visual acuity in an eye exam. In this check you will be provided with a high contrast eye chart with black letter slowly merging in the whiteboard background with each level. Your check continues till you give 2 consecutive wrong answers. A chart is prepared showing where exactly the answer went wrong and till what level you completed the check. NOTE: 1) Please make sure, the distance between you and the iPhone device should be 1 foot while performing any test. 2) This application is keypad-less i.e. no need of text inputs using keypad.
