Find blind spots on your retina.
Find blind spots on your retina.
Tutorial:
Follow the instructions in the app. Hold the unit as shown in Figure 2, right hand for the left eye. Hold the unit as shown in Figure 3, left hand for the right eye. The eye must be close to the red dot. The three fingers serve as a support. The nose must be on the thumb. Nothing may not touch the screen, otherwise the tapping does not work. You must ALWAYS aim at the red dot. If you saw a white dot, then type with the other hand and you hear a bong. After 10 points, there is a break and all dots are displayed. Green dots mean that you have seen. Yellow dots mean that you have not seen once. Blue dots mean that you have not seen twice. If you want to start from scratch, you can delete the old data by going to the app menu of Android and type "delete data".
