Huh – EyeChart - Vision Screening Review

It says to have it 4 feet away from you. How are you gunna know exactly 4 feet. It's an good app for free! But they should have an update to make it better. Like a test or something, then it calculates your eye score. It should have better than 20/20 vision, because there are people out there including me that have better than 20/20 vision. My eye doc Said I had better than 20/20. It just needs an update, then I'd rate it a 5.
